Circuit/System Testing

WARNING: This page is about a different car, the 2007 Pontiac G5 Pursuit, 2007 Pontiac G5, and 2007 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
  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.
