Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the hood ajar switch.
  2. Ignition OFF, test for less than 10 ohms 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 Hood Closed Switch and Hood Open Switch parameters are Inactive.
    • If not the specified value, test the appropriate signal circuit for a short to ground. If the circuit tests normal, replace the RIM.
  4. Install a 3A fused jumper wire between the signal circuit terminal A and ground. Verify the scan tool Hood Open 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 RIM.
  5. Install a 3A fused jumper wire between the signal circuit terminal B and ground. Verify the scan tool Hood Closed 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 RIM.
  6. If all circuits test normal, test or replace the hood ajar switch.
