Circuit/System Testing
WARNING: This page is about a different car, the 2010 GMC Terrain and 2010 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition OFF, disconnect the harness connector at the P24 Park Assist Display.
- Ignition ON, test for greater than 11 V between the B+ circuit terminal A and ground.
- If less than the specified value, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K41 Parking Assist Control Module.
- Ignition OFF, disconnect the X1 harness connector at the K41 Parking Assist Control Module.
- Ignition ON, test for less than 0.3 V between the K41 Parking Assist Control Module control circuit terminals listed below and ground:
- Terminal 4 X1
- Terminal 9 X1
- Terminal 10 X1
- If greater than the specified value, test the control circuit for a short to voltage.
- Ignition OFF, test for infinite resistance between the K41 Parking Assist Control Module control circuit terminals listed below and ground:
- Terminal 4 X1
- Terminal 9 X1
- Terminal 10 X1
- If less than the specified value, test control circuit for a short to ground.
- Test for less than 5 Ω between the control circuit terminals listed below:
- K41 Parking Assist Control Module terminal 4 X1 and P24 Park Assist Display terminal B
- K41 Parking Assist Control Module terminal 9 X1 and P24 Park Assist Display terminal C
- K41 Parking Assist Control Module terminal 10 X1 and P24 Park Assist Display terminal D
- If greater than the specified value, test the control circuit for an open/high resistance.
- If all circuits test normal, connect the X1 harness connector to the K41 Parking Assist Control Module, replace the P24 Park Assist Display and verify the DTC does not reset.
- If the DTC resets, replace the K41 Parking Assist Control Module.
