Circuit/System Testing
WARNING: This page is about a different variant/trim than selected.
- 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 .
- Ignition OFF, disconnect the 3-phase cables from the K59 starter generator control module.
- Test for infinite resistance to 3-phase circuit terminals listed below and ground:
- X8 phase U terminal
- X7 phase V terminal
- X6 phase W terminal
- If not the specified value, disconnect the 3-phase cables from the A15 starter generator, and test the 3-phase circuit for a short to ground. If the circuit tests normal, replace the A15 starter generator motor.
- Replace the K59 starter generator control module. If the DTC resets replace the A15 starter generator.
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.
