Group 43 MID 130 Transmission Control Unit, Fault Codes 43 Type of fault: FMI Description: Fault Condition: Possible Symptoms: Possible Cause:
FMI 7 • Mechanical system not responding or out of adjustment • The clutch does not disengage/en- gage properly when commanded and, • There is no active fault code on the SEPoC and, • The mechanical system of the clutch does not work correctly • There is no active fault code for low air pressure and, • There is no active fault code on any of the clutch cylinder valves and, • The PCB temperature is above 10°C (50°F) • Yellow lamp is sent • Slow gear changes • Erratic clutch performance • Clutch • Clutch cylinder • Clutch cylinder air hose • Clutch valve assembly • Clutch valve assembly air supply FMI 8 • Clutch system • Low system air pressure • Set point for clutch position can not be reached using normal actuator control Limit for using actuator valves exceeded Clutch position is outside tolerance at disengaged position • Yellow lamp is sent • Harsh start • Harsh shifting • Slow shifting • Slow clutch engagement at start • Air leakage from the following component(s):
Clutch cylinder Clutch valve assembly Clutch cylinder air hose Clutch cylinder air connection FMI 11 • Clutch drag • The clutch transfers too much torque in the disengaged position • Yellow lamp is sent • The vehicle tends to creep on flat ground at idle • The clutch wear is high • Clutch • Warped flywheel • Transmission input shaft FMI 12 • Unintentional clutch slip • The clutch cannot transfer a specific torque without slipping • Yellow lamp is sent • The engine torque is reduced so that the clutch does not continue to slip • Clutch
