Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the ignition switch.
  2. Ignition ON, verify that a test lamp illuminates between the ignition 1 voltage supply circuit and ground.
    • If the test lamp does not illuminate, repair the voltage supply circuit for a short to ground or an open/high resistance. If the ignition switch fuse is open, also test the signal circuit for a short to ground.
  3. Install a 3-amp fused jumper wire between the signal circuit and the voltage supply circuit. Verify the scan tool Key In Ignition parameter displays Yes.
    • If not Yes, test the signal circuit for an open/high resistance. If the circuit tests normal, replace the BCM.
  4. If all circuits test normal, test or replace the ignition switch.
