and WIRING DIAGRAMS
. Perform TEST VER-1B - VERIFICATION PROCEDURE
after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Turn ignition off. Disconnect Powertrain Control Module (PCM) harness connectors. PCM is located between left inner fender and power distribution center. Inspect connector terminals No. 59 and 60. Repair as needed and go to next step.
- Reconnect PCM harness connectors. Using scan tool, read PCM status. While observing scan tool, wiggle harness. If scan tool displays NO RESPONSE FROM PCM, inspect specified circuits between Body Control Module (BCM) and PCM for open. See CCD BUS CIRCUIT IDENTIFICATION table. If scan tool does not display NO RESPONSE FROM PCM, problem may be intermittent.
