  6. Disconnect key-in ignition switch connector. See Figure . Using scan tool in ohmmeter mode, measure resistance at key-in ignition switch connector terminal No. 2 (Black wire). If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open Black wire.
  7. Connect jumper wire between key-in ignition switch connector terminals. If scan tool shows KEY-IN IGNITION: CLOSED, replace ignition switch. If scan tool does not show KEY-IN IGNITION: CLOSED, go to next step.
  8. Gain access to BCM connector "A". Do not disconnect connector. Connect a backprobe jumper between ground and BCM connector "A" terminal No. 32 (Light Blue wire). If scan tool shows KEY-IN IGNITION: CLOSED, repair open Light Blue wire. If scan tool does not show KEY-IN IGNITION: CLOSED, go to next step.
