• Turn on machine in platform mode. If DTC 662 is present, troubleshoot
that DTC before continuing.
• See accessory module documentation for troubleshooting.
• 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.
• ZAPI - HEALTH (Status LED) - ON
• See accessory module documentation for troubleshooting.
• Refer to Drive Motor Electrical Evaluation in Section 3.5.
• Refer to Power Module Electrical Evaluation in Section 3.6.
• 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
• 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
• 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
• 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
• 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
