Circuit/System Testing
- Identify how to disable high voltage.
- Identify how to test for the presence of high voltage.
- Identify condition under which high voltage is always present and personal protection equipment (PPE) and proper procedures must be followed.
- Perform the High Voltage Disabling procedure for servicing the T6 power inverter module assembly or T12 transmission.
- Remove the X8 connector from the T6 power inverter module.
- Test for infinite resistance between the AC circuit terminals listed below and ground:
- Terminal 1 phase W
- Terminal 2 phase V
- Terminal 3 phase U
- If not the specified value, replace the G5 auxiliary transmission fluid pump motor.
- If the circuit tests normal, replace the T6 drive motor power inverter module. If the DTC resets, replace the G5 auxiliary transmission fluid pump motor.
WARNING:
Always perform the High Voltage Disabling procedure prior to servicing any High Voltage component or connection. Personal Protection Equipment (PPE) and proper procedures must be followed.
The High Voltage Disabling procedure will perform the following tasks:
Failure to follow the procedures exactly as written may result in serious injury or death.
