664
CANBUS FAILURE -
ACCESSORY MODULE
An accessory module has
stopped communication.
•
Turn on machine in platform mode. If DTC 662 is present, troubleshoot
that DTC before continuing.
•
See accessory module documentation for troubleshooting.
6635
CANBUS FAILURE - CHASSIS TILT
SENSOR
Chassis Tilt Sensor messages not received for
1000 mS while B+ is present on J1-28
•
The control system failed to receive messages from the Chassis Tilt Sensor
located inside the Ground Control Box.
•
Ensure that +B is present on pin 1 of the sensor, and -B is present on pin
4. Check the CANbus wiring to pins 2 and 3 of the sensor.

DTC
FAULT MESSAGE
DESCRIPTION
CHECK
771
OPEN CIRCUIT DRIVE
MOTOR WIRING
The power module detected a
problem in the drive motors'
power circuit wiring.
•
Refer to Drive Motor Electrical Evaluation in Section 3.5.
•
Refer to Power Module Electrical Evaluation in Section 3.6.
772
STALLED TRACTION MOTOR OR
POWER WIRING ERROR
Drive, Steer, and Lift Prevented
•
The System Module detected armature current feedback > 4.5V or <
0.5V. This is mostly likely caused by a stalled traction motor or power wir-
ing issue. Alternately, it could be an internal fault.
•
ZAPI - HEALTH (Status LED) - ON
773
CAPACITOR BANK FAULT - CHECK
POWER CIRCUITS
Drive, Steer, and Lift Prevented
•
There is an internal or external fault that prevents the System Module’s
capacitor bank from charging.
•
The System Module detected that the VMN of the pump and traction has
not increased more than 1.3V in 1000mS. Alternately, the VMN of the
pump or traction is less than 20% of battery voltage.
•
If this message persists after disconnecting the drive and pump wiring,
there is an internal fault.
•
ZAPI - HEALTH (Status LED) - ON
774
SHORT CIRCUIT FIELD WIRING
Drive, Steer, and Lift Prevented
•
The field wiring passed System Module power-up diagnostics. However,
an external short circuit was detected when current was applied to F1 /
F2. This situation is caused by improper field wiring or a damaged motor.
•
ZAPI - HEALTH (Status LED) - ON
775
OPEN CIRCUIT FIELD WIRING
Drive, Steer, and Lift Prevented
•
The System Module applied field current, but could regulate the desired
current. The situation is caused by improper field wiring or a damaged
motor.
•
ZAPI - HEALTH (Status LED) - ON
776
STALLED PUMP MOTOR OR
POWER WIRING ERROR
Drive, Steer, and Lift Prevented
•
The System Module measured improper pump current feedback (>4.5V
or <0.5V) for 240mS. This is caused by a stalled pump motor, a power
wiring issue, or a System Module malfunction.
•
ZAPI - HEALTH (Status LED) - ON
