46 130 MAIN CONTACTOR / REAR RIGHT BRAKE
RETURN - SHORT TO BATTERY 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
Brake FET Power cycle
46 104 REAR LEFT SPEED SENSOR - NOT RESPONDING
PROPERLY Associated Power Module has detected an encoder
or directional sensing problem Power cycle
46 105 REAR RIGHT SPEED SENSOR - NOT RESPONDING
PROPERLY Associated Power Module has detected an encoder
or directional sensing problem Power cycle
46 108 REAR LEFT SPEED SENSOR - RPM HIGH Associated Power Module determines an over-
speed condition (measured motor speed > DRIVE
MAX + 15Hz) has occurred on a motor Power cycle
46 109 REAR RIGHT SPEED SENSOR - RPM HIGH Associated Power Module determines an over-
speed condition (measured motor speed > DRIVE
MAX + 15Hz) has occurred on a motor Power cycle
46 136 REAR LEFT BRAKE SUPPLY VOLTAGE – OUT OF
RANGE LOW Associated Power Module determines that a low
parking brake supply voltage condition exists. Power cycle
46 137 REAR RIGHT BRAKE SUPPLY VOLTAGE – OUT OF
RANGE LOW Associated Power Module determines that a low
parking brake supply voltage condition exists. Power cycle
66 2 CANBUS FAILURE - PLATFORM MODULE UGM does not receive any CAN messages from Plat-
form Module in 250ms CAN1 messages are received from the PM and
controls are initialized
66 3 CANBUS FAILURE - LOAD SENSING SYSTEM
MODULE MACHINE SETUP -> LOAD SYSTEM ≠ NO;
UGM does not receive any CAN messages from the
LSS module in 1000ms Not all of the trigger conditions are met; motion
restrictions removed after controls initialized
66 13 CANBUS FAILURE - EXCESSIVE CANBUS ERRORS UGM observes more than 22 error frames per sec-
ond for 4 seconds or more than 500 Buss Off condi-
tions since last power cycle.

66 35 CANBUS FAILURE - CHASSIS TILT SENSOR UGM does not receive any CAN1 messages from
Chassis Tilt Sensor in 250ms CAN1 messages are received from the sensor and
controls are initialized;
66 54 CANBUS FAILURE - REAR LEFT MODULE After Startup complete, Power Module CAN2 mes-
sages are not received in 200ms UGM receives all traction modules CAN2 mes-
sages and shall command main contactor closed;
once fault reset, motion permitted after controls
are initialized.
If CAN messages are lost more than 5 times, the
fault shall be latched until Power Cycle.G352
66 55 CANBUS FAILURE - REAR RIGHT MODUL After Startup complete, UGM or Power Modules not
receive the designated CAN messages in 200ms
(250ms for UGM) UGM receives all traction modules CAN2 mes-
sages and shall command main contactor closed;
once fault reset, motion permitted after controls
are initialized.
If CAN messages are lost more than 5 times, the
fault shall be latched until Power Cycle.
66 57 CANBUS FAILURE - TEMPERATURE SENSOR 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.
UGM receives CAN1 messages from the Ambient
Temperature sensor; speed restrictions removed
after controls initialized
77 25 PUMP MOTOR - NOT RESPONDING The Master Traction Module detects that the pump
motor feedback is not responding when the pump
is being commanded Power cycle
