Common Problems This ECM Can Address

• No-start condition after ECM failure
• Intermittent stalling or loss of engine control
• Check engine light caused by module faults
• Communication issues between the ECM and vehicle systems
• Driveability problems traced to internal control module damage

Installation Notes

Flash programming is required before or during installation, and accurate VIN and mileage information are needed. Verify the OE number on the original module before ordering, since the wrong ECM can prevent the vehicle from starting. Prior to replacement, inspect grounds, power feeds, wiring harness condition, and related solenoids or relays to confirm the original module is the source of the fault.

For Chrysler PCM applications with a V suffix, VIN programming is required. If the vehicle uses theft-deterrent programming, follow the OE service procedure for the specific system before returning the vehicle to service.

Quality Assurance

Cardone remanufactures this ECM using reverse engineering to identify original design weaknesses and correct them during the rebuild process. Critical components are re-soldered or replaced, and each unit is computer tested to verify operation before release.
