For the last 18 months or so, the van would not start although the charging system, etc was fine. It would display a ‘done’ code in the mileage area. After it sat for indefinite periods of time it would start just fine without a jump and run fine. The dealer replaced the starter (unnecessarily; the problem persisted. Next they unnecessarily replaced the battery; the problem persisted. Next it would show the ‘done’ code as well as a ‘P0601’ code. Today, the dealer replaced the PCM and 20 minutes later the problem is still there. We’ve spent over $2,000.00 on this vehicle and are basically afraid to shut it off for fear of not starting. It has 100,000 miles and otherwise runs fine. Several dealers say they’ve never encountered the ‘done’ problem. Please advise

The code you gave stands for “Internal Control Module Memory Check Sum Error”. This may be refering to the BCM module and not the PCM. It sounds like the service department may be guessing at the trouble rather than using proper troubleshooting methods. If the trouble goes on for a while the tech should be able to look for good test points to check for proper voltage while trying to start the engine and pin down the area of trouble.
