Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the key in ignition switch.
  2. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 3 and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal and the ignition switch fuse is open, test the signal circuit terminal 5 for a short to ground.
  3. Verify the BCM scan tool Key In Ignition Status parameter is Key Out.
    • If not the specified value, test the signal circuit terminal 5 for a short to voltage. If the circuit tests normal, replace the BCM.
  4. Install a 3-amp fused jumper wire between the key in ignition switch signal circuit terminal 5 and the voltage supply circuit terminal 3. Verify the BCM scan tool Key In Ignition Cylinder Switch parameter is Key In.
    • If not the specified value, test the signal circuit for an open/high resistance. If the circuit tests normal, replace the BCM.
  5. If all circuits test normal, test or replace the ignition switch.
