- Ignition OFF, disconnect the X3 harness connector at the turn signal/multifunction switch.
- Test for less than 20 ohms between the low reference circuit terminal M and ground.
- If greater than the specified range, test the low reference circuit for an open/high resistance.
- Ignition ON, verify the scan tool Windshield Washer Switch parameter is Inactive.
- If not the specified value, test the signal circuit terminal L for a short to ground. If the circuit tests normal, replace the BCM.
- Install a 3A fused jumper wire between the signal circuit terminal L and the low reference circuit terminal M. Verify the scan tool Windshield Washer Switch parameter is Active.
