DTC Text
At Startup, the Master Traction Module detects an
overcurrent condition on pin A12, indicating a
short between B+ and the Main Contactor.
During active traction, the Master Traction Module
detects an overcurrent condition on pin A4. Electric

Associated Power Module has detected an encoder
or directional sensing problem

Associated Power Module determines an over-
speed condition (measured motor speed > DRIVE
MAX + 15Hz) has occurred on a motor

UGM does not receive any CAN messages from Plat-
form Module in 250ms
MACHINE SETUP -> LOAD SYSTEM ≠ NO;
UGM does not receive any CAN messages from the
LSS module in 1000ms
ond for 4 seconds or more than 500 Buss Off condi-
tions since last power cycle.
UGM does not receive any CAN1 messages from
Chassis Tilt Sensor in 250ms
After Startup complete, Power Module CAN2 mes-
sages are not received in 200ms
After Startup complete, UGM or Power Modules not
receive the designated CAN messages in 200ms
(250ms for UGM)
UGM determines that:
• MACHINE SETUP TEMP CUTOUT = YES
• UGM does not receive any CAN1 messages from
the Low Temperature Cutout sensor in 250ms
Suppress DTCs 241 and 242 if this DTC is active.
The Master Traction Module detects that the pump
motor feedback is not responding when the pump
is being commanded
