Circuit/System Verification

WARNING: This page is about a different variant/trim than selected.

Perform the High Voltage Disabling procedure for servicing the T6 Power Inverter Module or the T12 Transmission.
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:
- 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.
Failure to follow the procedures exactly as written may result in serious injury or death.
Disconnect the X4 harness connector at the T6 Power Inverter Module.
Test for infinite resistance between the each of the AC circuit terminals listed below and ground for each phase of the G5 Transmission Fluid Pump - Electric/Auxiliary:
- Terminal 3 phase U
- Terminal 2 phase V
- Terminal 1 phase W
- If less than infinite resistance
  Replace the G5 Transmission Fluid Pump - Electric/Auxiliary.
- If infinite resistance
Verify DTC P1E39 does not set.
- If the DTC sets
1. Perform each of the operations listed below one at a time until the fault is corrected.
  1. Program the T6 Power Inverter Module.
  2. Replace the T6 Power Inverter Module.
  3. Replace the G5 Transmission Fluid Pump - Electric/Auxiliary.
2. Repeat the DTC check.
- If the DTC does not set
All OK
