  1. Ignition OFF, Retained Accessory Power OFF, disconnect the X1 harness connector at the S82 Windshield Wiper/Washer Switch.
  2. Ignition OFF, test for less than 5 Ω between the ground circuit terminal 2 and ground.
    • If greater than the specified value, test the ground circuit for an open/high resistance. If the circuit tests normal, replace the K9 BCM.
  3. Ignition ON, test for B+ between the signal circuit terminal 3 and ground.
    • If less than the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 BCM.
  4. Test for B+ between the signal circuit terminal 5 and ground.
    • If less than the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 BCM.
  5. Test for B+ between the signal circuit terminal 1 and ground.
    • If less than the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 BCM.
  6. If all circuits test normal, test or replace the S82 Windshield Wiper/Washer Switch.
