PCM Harness Resistance
Turn ignition switch to LOCK position. Disconnect PCM and appropriate component harness connectors. Check for open or short circuits between appropriate PCM harness connector terminal and appropriate component harness connector terminal. See POWERTRAIN CONTROL MODULE (PCM) table. See WIRING DIAGRAMS. If harness is open or shorted, repair as necessary.
