NOTE: If engine will not start, crank engine for 15 seconds. Crank at least 2 times with the ignition switch returning to the OFF position each time.

With DRBIII(R), attempt to program PCM. See POWERTRAIN CONTROL MODULE  under PROGRAMMING. Start the engine and allow the engine to reach normal operating temperature. With the DRBIII(R), read DTCs. Does the DTC reset? If yes, replace PCM. Program the new PCM. See POWERTRAIN CONTROL MODULE  under PROGRAMMING. If no, test is complete.
