BMW GM II / General Module 2As far as I know BMW used the GM II on the E31, 8-series 1989-1999 . I am still trying to researching the GM2. This module does not contain any relays, but, it does contain the relay drivers. The relays are located in the A5, Relay Module. Not sure why they did that! Maybe to keep the size of the GM2 small. A little tid bit, according to Wikipedia only 7232 8-series were sent to the US and Canada in the 11 years of production. Only The GM II in the pictures below are from an 1997 840ci which a customer sent me to look at. It apparently is responsible for a current drain which depletes the cars battery in a couple of days or less. The BMW part number of this module is 61.35 6 957 038. This part number seems to still be available from ECS Tuning stock # 169162 for $424.56 (ouch) and from Tischer BMW for $354 via their parts web site www.getbmwparts.com. BMW ZKEIII, GM III, General Module 3 page The BMW GM III is used on several cars such as the E38 7-series 1994-2001, E39 5-series 1995-2004 and the E53 X5 2000-2006 series. I am still researching the GM3, but, it seems that there are more than a couple major types of GM3. One uses the 3 of the V23078-C1002-A303 relays and 2 of the V23072-C1061-A303 relays. The newest versions of the GM3 contains completely different relays. I will post information up on this web page as soon as I get it. Also check out the GM3 Part numbers web page that I've compiled. 02/12/2011 GM3 repairs available for certain problems. Contact me to find out if I can repair it. Coming Soon repair for GM3 modules that no longer have remote door locks, no interior lights and in some cases no wipers. GM3 Connections web page Unlike the GM5 used in the E46, 3-Series, the GM3 does not supply power to the front door lock motors or the front window motors. They are instead connected via the P-Bus to the PM-FT/SB modules, 1 in each of the two front doors. The PM-FT/SB modules detect the state of the key cylinder via two hall sensors and the open/closed state of the door via another hall sensor. Each PM module is responsible for powering the window motor and the door lock motor. The door lock motor is powered by an H-bridge power MOSFET output circuit. This is good since MOSFETs do not wear out like relays. Check out my new PM Module web page. GM3 module, P/N 61.35-8 378 631. The module has 5 relays inside. Three are the familar V23078-C1002-A303 that are used for front windows in the GM4 and GM5 modules and two are the V23072-C1061-A303 which is also used in the GM4 module. Later modules use the V23072-C1061-A309 which I do not stock. GM3 module, P/N 61.35-6 920 822 from a 2003 X5 (E53). The board is slightly different from the module I got from a late 90's 7-series. PC board says Rev. G. The other module says Rev. E. GM3 module, P/N 61.35-6 946 947. This module is a complete redesign from the earlier module. Several relays have been replaced with solid state drivers. Two relays remain (front window) that are a new part number to me and I do not have any. U1 - Servotronic Solenoid Driver (power from X332-1, output to X254-11) U2 - Windshield Washer Pump Driver (power from X254-10, output to X254- 18) U3 - Alarm Siren Driver (power from X254-10, output to X254-17) U4 - Interior Lights Driver (power from X254-10, output to X254-20) U5 - Interior Lights Driver (wired in parallel with U4) U6 - Switch off consumer load (power from X254-10, output to X254-19) U7 - BTPIC0106K, Dual Out Driver - Pin 1 to X254-7 Bottom Tailgate Motor and Pin 7 to X254-16 Upper Tailgate Motor (power from X332-1) RLY1 - Rear Right Window Motor Relay V23078-C1002-A303 (power from X254-4, output to X254-5&15) RLY2 - Rear Left Window Motor Relay V23078-C1002-A303 (power from X254-4, output to X254-2&12) RLY3 - Rear Door Lock Relay V23078-C1002-A303 (power from X254-4, outputs X254-6 rear door locks, X254-14 unlock rear doors and gas flap) RLY4 - Rear Door Lock Relay V23072-C1061-A303 or V23072-C1061-A309 depending on board rev (power from X254-4, output to X254-13 lock rear doors) RLY5 - Rear Door Lock Relay V23072-C1061-A303 or V23072-C1061-A309 depending on board rev (power from X254-4, output to X254-3 rear lid lock motor) Below is a picture of GM3 P/N 61.35-6 920 822 from an 03 X5 E53. The GM3 is located behind the glove box. I found removal instructions for the E38 7-series <removal instructions>, but, not for the E39 5-series (located behind the glove box) or the E53 X5 (located by the rear fuse box).

Also used on the Z3 coupe and roadsters from model year 1997 until end of production. One thing I saw said these modules where made by Hella, but, I think mine is made by UTA (United Technologies Automotive). What does the GM4 module do? It controls interior lighting, central locking (door locks, trunk and fuel filler door), door lock heater, power windows and power sunroof. The GM4 is located behind the glovebox above the Relay Module 4 (RMIV) and Washer/Wiper Module. This module uses 5 relays. Two of them are the familar V23078-C1002-A303 relays, available here, that are also use on the BMW GM3 and GM5 modules. The other three relays are V23072-C1061-A303, available here, that are also used in the BMW GM3 module. I have arbitrarily numbered the relays in the picture below. Relays 1 & 2 are V23078-C1002-A303. RLY1 is for the front driver side window. RLY 2 is for the front passenger side window. Relays RLY3, 4 and 5 are V23072- C1061-A303 and are used together to control the door locks. For rear window control the GM4 connects to theRelay Module 4 or RMIV. This module contains a pair of V23078-C1002-A303 relays as well. BMW PM-BT module The PM module is used on cars that use the BMW GM3 module like the E38 7-series 194-2001 and E39 5-series 1995-2004. I thought that the E53, X5 would use this module too, since it uses the GM3, but, it doesn't appear on realoem.com. On these cars there is one PM module in each of the Front Door. The module is connected to the GM3 through the P-Bus. It controls the door lock, window motor, mirror motors and mirror heater. It senses the seat memory switch, door latch, window switch and mirror adjust switch and controls the appropriate motor directly and/or notifies the GM3 module via the P-Bus. If you are looking at the car wiring diagram you will see connector numbers X1128, X1129 & X887 on the drivers side door and connector numbers X1130, X1131 & X889 on the passengers side. The window motor is controlled via a V23078-C1002-A303 relay (I sell this relay by the way) and the door lock is controlled via a Solid State Driver IC, ST Microsystems L9947S. The GM III were made under a variety of part numbers including the following.

BMW Relay Module 4 or RMIV The BMW Relay Module 4 or RMIV is used on the E36 3-series sedans from model year 1994 until the end of production. The P/N of my unit is 61.35-8 353 099. There are many P/Ns. What does the RMIV do? In conjunction with the GM4 it controls the rear power windows. The RMIV is located behind the glovebox below the GM4 module. Below is a picture of my RMIV module. This module uses 2 relays. The familar V23078-C1002-A303 relays, available here, that are also use in the BMW GM3, GM4 and GM5 modules to control power windows. I have numbered the relays and when I find out I will explain what each relays does. One is for the left windows and one is for the right. I will update when I find out.

These are the relays used to control the rear door lock actuators in cars that use the GM III (ZKE III) module. The GM III is used in the E38 (7-series), the E39 (5- series) and the E52 (X5). These are the relays used to control the front door lock actuators in cars that use the GM IV (ZKE IV) module. The GM IV is used in the E36 (3-Series), E36/7 (Z3 Roadster) and the E36/8 (Z3 Coupe). <-- BMW GM III module RELAY Tyco V23084-C2001-A303 Relay Only $15 each plus $3 shipping within the US or $6 shipping outside the US. These relays are used in almost all GM5 modules found in the E46 3-series (except in some late 2004 and 2005 cars). Two relays used for the power door locks and should be replaced in pairs. Two relays are used for the rear windows, one per window. It is also used on some of the E46 memory seat modules like the 52.10-7 019 255 which can be found in 2002 and later convertibles with the memory seat option. Not sure which other cars use this module. The memory seat module uses 4 of these relays Before you purchase some notes on replacing the relays yourself These relays are not in sockets. They are soldered into the board and are very difficult to get out. If you have a little Radio Shack soldering iron and think you're going to get these relays out, think again! The copper planes suck away the heat faster than a lot of these little irons can put out. Also the solder used is RoHS or lead free which melts at a higher temperature, about 422°F compared to eutetic tin- lead which melts at 361°F. This makes it very difficult to get all the solder out of the holes. Thinking of using solder wick? Forget it. It's not going to work. Don't believe me. I can give you names and email addresses of people who tried it themselves and messed up their modules. I have created another web page on some common problems encountered removing these relays. Common Problems web page The front window relays are even harder to get out than the door lock relays. The old relays need to be removed by someone who is skilled at desoldering. <-- BMW GM IV module RELAY Tyco A1001-C133 V23133- Relays Also known as V23133-A1001-C133 Looking for the Tyco or Siemens V23133-C133-A1001 relay used in the BMW RM1 Module?

Auction #320539673520 Some information on the BMW FZV Antenna Amplifier BMW Key Fob Repair - FZV Antenna Amplifier Repair I just finished doing a little testing on the FZV antenna amplifier. I'm doing this because there have been a few people telling me that they can't code their key to their car (See recoding procedure) and are wondering if replacing the relays will help. NO, it won't help. The relays will only help in cases where one or more door locks don't unlock (and in very rare cases won't lock). If your key doesn't start the car please check out my EWS web page. If your car doesn't do anything when the key fob buttons are pressed, no locking, no unlocking, no trunk release, no interior lights (when unlock is pressed), no alarm beep then recoding may help, but, first check one thing. Get in the car, close all the doors, put the key in the ignition turn it to On then turn it back to Off. Open the door, the car should beep at you to tell you that a key is still in the ignition. Now remove the key, if the car continues to beep then there is a problem with the key sense switch in the ignition. If a key is sensed in the ignition it will inhibit all key fob functions. If the car stops beeping when the key is removed then ry recoding the key, but, only if the car does not respond to any of the key fob buttons. Note that if the car continues to beep after the key is removed DO NOT perform the key recode procedure. The car won't accept it and performing the button sequence on the key will unsync the key from the car. If the car intermittantly responds to the key fob or if there is not response and key recoding didn't help then there are several possible causes. It could be the key fob itself or the battery, it could be the antenna on the rear windshield (in the rear view mirror on the convertible) it could be the FZV antenna amplifier, it could be the GM5 or the wiring. So far I've only seen problems where the FZV antenna amp was bad and replacing it solved the problem. I've heard on the forums that replacing the battery has solved problems for people. A lot of people incorrectly assume that it must be the battery. If the car only fails to LOCK and no interior lights come on when lock is pressed then it could be the battery. A low battery condition causes problems with LOCKING only. A bad battery will cause no functions to work, but, rarely will a battery go from working properly to bad in a short period of time. Even the low battery condition can come and go over the course of weeks due to battery temperature, with cold temperatures making the problem worse. If you still suspect the key is bad and want it fixed or want the P/N for a new one then go over to my E46 key web page. Ok, so let me start off with a brief explanation of how the whole system works. When a button on the key fob is pressed a digital message is modulated on a 315MHz (453MHz on some cars) carrier and transmitted like a little radio station. An antenna on the rear window glass (in the rear view mirror on convertibles or in the tailgate lid on wagons) receives the RF signal and sends it to the FZV antenna amplifier located on the C-pillar usually on the left hand side (on convertibles it's located in the rear view mirror housing). Here it is on my 4-door with the C-pillar cover removed. The FZV antenna amplifier demodulates the signal and sends a +5V digital baseband signal to the GM5 (aka ZKE5) module. The output on the FZV module is X1143 pin 3 and input on the GM5 module is X253 pin 49 (X253 is the center connector on the GM5). The wire color is blue with a red stripe. If you are looking at the BMW WDS, the FZV antenna amplifier is module "N8" and the GM5 is module "A1". Below are a couple scope captures looking at the baseband signal out of the FZV module. The picture on the left is the whole message. It varies in length from press to press from about 0.19 seconds to about 0.32 seconds. This line normally sits at +5.0V and drops to nearly zero to indicate presence of a RF signal from the key fob. If you don't have an oscilloscope you can check for the presence of a signal using a simple DMM. If you use the DC Volts scale and measure from this signal to ground you will measure +5.0 Volts and when a button is pressed the line should drop to a minimum of +2.5 Volts for a fraction of a second. Don't worry if you don''t see +2.5 Volts, but, instead see some other number that is between +2.5 and +4.5, this is fine. It all depends when the meter sampled the signal. You can also set the meter to AC Volts. In this setting you will see zero volts most of the time and it will jump to about +2.5 Volts when a signal from the key is received. If you see that you are getting a signal on this line and following the key recoding procedure doesn't work then it's probably the GM5 module, but, I think this would be a very very rare failure mode. More likely you will not see a signal and the problem is in the wiring, the FZV antenna amplifier module or in the key fob. If you have had a problem with your key fob not working with the car and found out what was causing the problem please shoot me an email (
[email protected]). I'd love to know what resolved the problem in your case. E46Fanatics thread on the differences between the 1999-2001 and 2002-2005 FZV antenna amplifiers. http://forum.e46fanatics.com/showthread.php? t=662688 New Information: Jez just emailed me to say that his problems are fixed. In his case the car stopped responding to the keys. Multiple attempts to reprogram the car to the key didn't work. He measured the signal going into the GM5 from the FZV and there was no signal, just 5V with no dip when the key fob buttons are pressed. He finally located a FZV for his E46, 3-series wagon at a salvage yard and installed it. Presto everything works fine now. Key reprogramming worked the first time, alarm arms & disarms, remote trunk release works, remote door locks work. Problem was not the GM5 module or the key fob battery like he initially guessed.

These relays are P/N: V23078-C1002- A303 and made by Siemens Price is $16 each including shipping within the US and $20 each including shipping to anywhere outside the US. These are the relays used to control the front windows in cars that use the GM4 (ZKE4, GMIV), GM5 (ZKE 5) module. These cars include the E46 (3-series), E85 (Z4), E83 (X3) and E52 (Z8). It is also used in the GM3 (ZKE III) module to control the rear windows and rear door locks. The GM3 is used in the E38 (7-series), the E39 (5- series) and the E52 (X5). It is also used in theRelay Module 4 (RMIV) on E36 3-series. What's this E-number business? Not sure what your car is? Check out the excellent BMW timeline at the bottom of this page on Wikipedia. http://en.wikipedia.org/wiki/BMW_E85 Every GM5 module that I've worked on or seen has used this relay for the front windows. It doesn't seem to matter if the car is for the US, UK, etc, markets. The GM5 is located behind the glove box in a white plastic module holder. Someone on the net made a really good "How To" on removing the GM5 from the car. You can download it here, GM5 Removal Procedure. I don't know who the author is, but, I want to give him credit for taking the time to create this How To. I created my own how to remove the GM5 module which you can find here My GM5 Removal Procedure. Which relay controls what windows. Being the curious person I am, while my GM5 was going in and out of my car for testing of the door lock issue I decided to figure out what the other relays did. I wired up little LEDs in parallel with the relay coils and started rolling my windows up and down. These relays are doubles so each relay has two functions. See the picture below. The large relays are for the front windows and the smaller relays are for the rear windows. BTW the smaller relays, V23084-C2001- A303 are the same as those used on the door locks, so if you need a pair of those click on the part number and it will take you to my information page.

The higher cost on eBay is to offset the ever increasing eBay fees! What's the turn around time? I you paid for Express Mail next day return shipping I try my best to ship the modules back the same day I receive them. So, if you ship it to me next day air I will do the repair within hours of receiving it and get it to the post office before the 4pm Express Mail deadline. In this case door to door turn around time is about 48 hours. If you paid for Priority Mail return shipping, I will repair it and ship it back within 24 hours. All repairs will be done at an antistatic workstation by a competant tech. Unfortunately I won't be able to test it out after the repair, but, I will clean it and carefully inspect it under a microscope to verify that it was done correctly. I want to do it myself and just need the relays. I will sell them to you, but, I don't recommend doing this job yourself unless you are a competant solderer. The relays are very hard to get out due to the large copper area on the component side of the board and the use of lead free solder which has a higher melting point than the old tin- lead solder. Forget about trying to use solder wick. This is not an easy job and you risk damaging the board, plated through holes and having to replace the entire module at significant expense. With that said, the cost of the relay is $16 each including shipping within the US and $20 each including shipping to anywhere outside the US. Payment via PayPal is prefered. My account is

Other Options: Don't want to get your GM5 module repaired? You could go to the dealer and buy a new one. They're about $550- $700 plus $120/hour for labor. There is also Bavarian Auto Recycling, they have used GM5 modules for sale for 52- 85% off the current BMW list price, but, remember these are pulls from cars being parted out. You have no idea how much life is left in these relays and they may fail at any time. Plus the dealer will have to program it to correctly work in your car. Got a comment?

In general they all use the GM5, but, there are lots of different part numbers. I've personally cracked open 10 different part numbers of GM5 and they are mostly the same aside from board relayouts to move all components to one side of the board to make it cheaer to assembly. The major difference is some GM5's only have 4 relays instead of the usual 6. The two missing relays are for the rear windows. Also GM5 modules for the Z4 have a different case (insides are pretty much the same though). The Z4 case is made with mounting flanges so that it can be screwed down to the car. For the 3-series there are no flanges because the module slides into a module rack. I do not have a break down of which P/N's have all 6 relays and which have 4. Sorry, I forgot to keep track. If you get a new module from the dealer you won't get the same P/N as a replacement. BMW has one part number (ok, two. One with mounting flange for the Z4 and one without for the 3-series). The latest P/N for the 3-series is 61359161931. This unit has all 6 relays inside and can be used as a replacement for any 3-series, 4dr, coupe, wagon or convertible. It is uncoded and therefore needs to be taken to the dealer to be coded for your car. Cost is about $750 for the dealer to replace and code the new unit. In most cases the module doesn't need to be repaired, but, just repaired. Consider taking advantage of my repair service.

So far I've worked on at least 15 different part numbered GM5 modules. Everyone so far has used the same door lock and window relays. Not sure how up to date it is. I suspect that this module is different depending if the car has a sunroof, convertible, coupe, but, realoem.com doesn't make a distinction. On the web I saw a picture of another GM5 that only had 4 relays to my 6 (this was probably from a coupe or convertible).
