Possible failure modes: 1. Switch failed. 2. External wiring failure (damaged wires, loose connectors, or bent pins). 3. Armrest controller internal failure (power supply or signal sensing failed). Solution: Test the switch function, wiring, and the function of the armrest controller. NOTE: The transmission gear selection switch information is broadcast over the Data Bus. The transmission gear selection switch can be monitored using the MONITOR window in the service tool and selecting Armrest Trans Shift Switch - Shift Down and Armrest Trans Shift Switch - Shift Up. 1. Open the armrest controller housing and disconnect connector J211. 2. Test the transmission gear selection switch and its wiring. Pay attention to wiring damage, loose connectors, or bent pins. a. When the switch is in SHIFT UP position, there should be continuity between pin 1 and pin 2 and no continuity between pin 1 and pin 3. b. When the switch is in SHIFT DOWN position, there should be continuity between pin 1 and pin 3 and no continuity between pin 1 and pin 2. c. When the switch is in OFF position, there should be no continuity between any two of pin 1, pin 2, and pin 3. If the switch is not functioning as specified above, replace the switch. 3. Check controller function: a. Cycle the key switch to OFF, then to the ON position. Measure the voltage output from the controller at pin 1 of J211. It should be approximately 12 volts. b. Short pin 1 to pin 2 to simulate the shift up function. Short pin 1 to pin 3 to simulate the shift down function. Monitor the switch status on the monitor screen of the service tool. If the controller does not function properly, replace the armrest controller. 9-61 Template Name: OML_2_col Template Date: 2001_03_06 Rac 0-00000 SECTION 55 - INSTRUMENT CLUSTER (ICU2) - CHAPTER 9 TRANSMISSION CONTROLLER CONFIGURATION AND CALIBRATION Important General Information • Before star ting the transmission calibration pr oc e d ur e, c h e ck th e wi r i n g h a r n es s a n d components for damage or loose connections. Replace or repair any damaged par t as necessary. • • Before calibrating the transmission controller, be sure the Standard Instrumentation (ICU) and Armrest (ARM) controllers are calibrated. Be sure that no persons are in front of or in back of the tractor during calibration. ! • • WARNING: Since the clutch calibration process involves engaging transmission clutches, this procedure should only be performed in open areas, free of obstructions. The tractor may experience a small amount of movement during calibration and the tractor operator should be ready to stop the tractor at any time.

Check the integrity of Data Bus at the passive terminators The following checks are basically looking into one end of the data . check for bad connection and damaged wire along the Data Bus. At pin 3. Make sure the connector CN2 to the instrument controller is plugged in. Solution: Make sure both the instrumentation controller and the PTO controller are functioning OK.controller is OK. go to next. the red wire. 3.
