Circuit/System Testing

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2008 GMC Yukon XL, 2008 GMC Yukon, 2008 Chevrolet Tahoe, 2008 Chevrolet Suburban, and 2008 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the I/P multifunction switch assembly.
  2. 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.
  3. 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.
  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.
    • 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.
  6. If all circuits test normal, test or replace the I/P multifunction switch assembly.
