Testing:

Turn ignition off. Connect DRBIII(R) to DLC. Turn ignition on and wait approximately one minute. Using the DRBIII(R), read DTCs. Does this DTC reset and is DRBIII(R) able to communicate with CTM? If yes, replace CTM. Perform BODY VERIFICATION TEST under VERIFICATION TESTS. If no, the conditions that set DTC are not present at this time. The following list may help in identifying the intermittent condition:
- With the engine running at normal operating temperature, wiggle related wiring harnesses to try and duplicate failure.
- Refer to any Technical Service Bulletin (TSB) that may apply.
- Visually inspect related wiring harnesses for any chafed, pierced, pinched or partially broken wires.
- Visually inspect related harness connectors for broken, bent, pushed out or corroded terminals.
Were any of the above conditions present? If yes, repair as necessary. Perform BODY VERIFICATION TEST under VERIFICATION TESTS. If no, test is complete.
