- Ignition OFF, disconnect the harness connector at the I/P multifunction switch assembly.
- Test for less than 1.0 ohm between the appropriate ground circuit listed below and ground:
- RPO X88/Z88 ground circuit terminal 3
- RPO Z75 ground circuit terminal 5
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Ignition ON, verify that the scan tool Park Assist Switch parameter is Inactive.
- If not the specified value, test the signal circuit terminal 2 for a short to ground. If the circuit tests normal, replace the object alarm module.
- Ignition OFF, connect a 3A fused jumper wire between signal circuit terminal 2 and ground.
- Ignition ON, verify that the scan tool Park Assist Switch parameter is Active.
- If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the object alarm module.
- If all circuits test normal, test or replace the I/P multifunction switch assembly.
