Circuit/System Verification

Ignition ON, observe the scan tool Park Assist Switch parameter while cycling the parking assist disable switch. The parameter should change

between Active and Inactive.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the I/P multifunction switch.

2. Test for less than 1.0 Ohms between the appropriate ground circuit listed below and ground:

* RPO X88/Z88 ground circuit terminal 3

* RPO Z75 ground circuit terminal 5

瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, verify that the scan tool Park Assist Switch parameter is Inactive.

瀚慖f 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.

4. Ignition OFF, connect a 3A fused jumper wire between signal circuit terminal 2 and ground.

5. Ignition ON, verify that the scan tool Park Assist Switch parameter is Active.

瀚慖f 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.

6. If all circuits test normal, test or replace the I/P multifunction switch.
