Multifunction Switch Circuit/System Testing

  1. Ignition OFF, disconnect the C3 harness connector at the turn signal/multifunction switch.
  2. Ignition OFF, test for less than 15 ohms of resistance between the ground circuit terminal M and ground.
    • If greater than 15 ohms, test the ground circuit for an open/high resistance. If the circuit tests normal, replace the body control module.
  3. Verify the scan tool Windshield Wiper Switch parameter is Off.
    • If not Off, test the signal circuit terminal N for a short to ground. If the circuit tests normal, replace the body control module.
  4. Verify the scan tool Wiper High Speed Switch parameter is Inactive.
    • If not Inactive, test the signal circuit terminal K for a short to ground. If the circuit tests normal, replace the body control module.
  5. Install a 3-amp fused jumper wire between the signal circuit terminal N and ground. Verify the scan tool Windshield Wiper Switch parameter is Switch Fault.
    • If not Switch Fault, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the body control module.
  6. Install a 3-amp fused jumper wire between the signal circuit terminal K and ground. Verify the scan tool Wiper High Speed Switch parameter is Active.
    • If not Active, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the body control module.
  7. If all circuits test normal, replace the turn signal/multifunction switch.
