PCM is located in right rear corner of engine compartment. Check PCM connectors for corroded or loose connections. Repair as necessary. Disconnect PCM connectors. Using DVOM, measure resistance between negative battery terminal and ground terminals at PCM harness connector. See WIRING DIAGRAMS . If resistance is more than 5 ohms, repair open in affected ground circuit. If resistance is 5 ohms or less, ground circuits are okay.
