WARNING: This page is about a different car, the 2010 GMC Sierra, 2010 GMC Cab & Chassis Sierra, 2010 Chevrolet Silverado, and 2010 Chevrolet Cab & Chassis Silverado. 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.
  2. Test for less than 1.0 Ω between the ground circuit terminal 3 and ground.
    • 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 rear object sensor control 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 rear object sensor control module.
  6. If all circuits test normal, test or replace the I/P multifunction switch.
