Circuit/System Testing
- Ignition OFF and all vehicle systems OFF, disconnect the X2 harness connector at the X50A Fuse Block - Underhood. It may take up to 2 min for all vehicle systems to power down.
- Test for less than 10 Ω between the X50A Fuse Block - Underhood ground circuit terminal 38 and ground.
- Ignition OFF.
- Test for less than 2 Ω in the ground circuit end to end.
- If 2 Ω or greater, repair the open/high resistance in the circuit.
- If less than 2 Ω, repair the open/high resistance in the ground connection.
- Connect the X2 harness connector at the X50A Fuse Block - Underhood and disconnect the X5 harness connector at the K9 Body Control Module, ignition ON.
- Verify the G52 Night Vision Camera Washer Pump is not activated.
- If the G52 Night Vision Camera Washer Pump is activated
- Ignition OFF, disconnect the X1 harness connector at the X50A Fuse Block - Underhood, ignition ON.
- Test for less than 1 V between the X50 Fuse Block - Underhood control circuit terminal 6 and ground.
- If 1 V or greater, repair the short to voltage on the circuit.
- If less than 1 V, test or replace the X50A Fuse Block - Underhood.
- If the G52 Night Vision Camera Washer Pump is not activated
- Connect a 10 A fused jumper wire between the control circuit terminal 9 X5 and B+.
- Verify the G52 Night Vision Camera Washer Pump activates.
- If the G52 Night Vision Camera Washer Pump does not activate
- Ignition OFF, remove the jumper wire, disconnect the X1 harness connector at the X50A Fuse Block - Underhood.
- Test for infinite resistance between the X50A Fuse Block - Underhood control circuit terminal 6 X1 and ground.
- If less than infinite resistance, repair the short to ground on the circuit.
- If infinite resistance
- Test for less than 2 Ω in the control circuit end to end.
- If 2 Ω or greater, repair the open/high resistance in the circuit.
- If less than 2 Ω, replace the X50A Fuse Block - Underhood.
- If the G52 Night Vision Camera Washer Pump activates
- Replace the K9 Body Control Module.
