Windshield Washer Switch Circuit Test

WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the X1 harness connector at the S82 windshield wiper/washer switch.
  2. Verify that a test lamp illuminates between the low reference terminal 2 and B+.
    • If the test lamp does not illuminate, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K9 BCM.
  3. Ignition ON, verify the scan tool Windshield Washer Switch parameter is INACTIVE.
    • If not the specified value, test the signal circuit terminal 5 for a short to ground. If the circuit tests normal, replace the K9 BCM.
  4. Install a 3 A fused jumper wire between the signal circuit terminal 5 and the ground circuit terminal 2. Verify the scan tool Windshield Washer 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 K9 BCM.
  5. If all circuits test normal, test or replace the S82 windshield wiper/washer switch.
