Circuit/System Testing
WARNING: This page is about a different car, the 2012 Buick Verano. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition OFF, remove the ignition key, open the driver door and disconnect the scan tool.
- Disconnect the X1 harness connector at the K41R Rear Parking Assist Control Module.
- Test for less than 5 Ω between the ground circuit terminal 7 and ground.
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Verify that the test lamp illuminates between the B+ circuit terminal 1 X1 at the K41R Rear Parking Assist Control Module and ground.
- If the test lamp does not illuminate, test the control circuit for an open/high resistance. If all circuits test normal, replace the K41R Rear Parking Assist Control Module.
- If all circuits test normal, replace the K41R Rear Parking Assist Control Module.
