Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the hazard switch.
  2. Test for less than 5.0 ohms of resistance between the ground circuit terminal C and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify the scan tool Hazard Lamp Switch parameter is Inactive.
    • If not the specified value, test the signal circuit terminal B for a short to ground. If the circuit tests normal, replace the BCM.
  4. Install a 3A fused jumper wire between the signal circuit terminal B and the ground circuit terminal C. Verify the scan tool Hazard Lamp Switch parameter is Active.
    • If not the specified value, test the signal circuit for a short to voltage or and open/high resistance. If the circuit tests normal, replace the BCM.
  5. If all circuits test normal, test or replace the hazard switch.
