DTC P1602: Pcm Not Programmed: Testing

  1. Attempt to program PCM. Turn the ignition on. Start the engine. If the engine will not start, crank the engine over for 15 seconds. Crank at least 2 times with the ignition switch returning to the off position each time. Allow the engine to reach normal operating temperature. With the DRBIII® scan tool, read DTCs. Does the DTC reset? If yes, go to next step. If no, the test complete.
    2. NOTE: Before continuing disconnect the PCM harness connector and check the related wiring terminals for corrosion, damage or terminal push out. Repair as necessary.
  2. Using the wiring diagram as a guide, inspect the wire harness and connectors. Pay particular attention to all power and ground circuits. If there are no possible causes remaining, replace and program the PCM. See PROGRAMMING .
