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.
