• Two rectangular connectors with 40-pin male terminals on each connector
• Aluminum housing for OE-style mounting and durability
• Critical components are re-soldered or replaced during remanufacturing
• 100% computer tested for functionality and reliability
• Flash programming required for vehicle-specific calibration
• Fits 2003 Chrysler Town & Country and 2003 Dodge Grand Caravan, N/A

Product Details

Cardone Engine Control Modules are remanufactured to meet or exceed original equipment performance. For the 79-7321V, Cardone uses reverse engineering to identify common failure points, then corrects those weaknesses during the remanufacturing process. This approach helps deliver stable electrical performance for Chrysler Town & Country and Dodge Grand Caravan ECM replacement needs, especially when the original module has failed due to internal circuit issues or calibration problems. This part cross-references Chrysler 04727321AA and Dodge 4727321AA for the same application.

What This ECM Helps Resolve

• No-start or hard-start conditions tied to a failed engine control module
• Check engine light concerns caused by ECM internal faults
• Communication or drivability issues after module failure
• Calibration problems requiring vehicle-specific flash programming
• Replacement needs for 2003 Chrysler Town & Country and 2003 Dodge Grand Caravan with OE numbers 4727321AA-AD or 5127684AA

Installation Notes

Before replacing the original ECM, verify the root cause of the failure. Common causes include poor grounds, power supply issues, damaged wiring harnesses, and shorted solenoids or relays. This module requires flash programming, and Chrysler PCM units identified with a “V” suffix need VIN programming. Confirm the OE number and application match before installation. For GM and Ford anti-theft or PATS-related procedures, follow the appropriate OE service information when applicable to your vehicle family.

Quality Assurance

Each Cardone remanufactured control module is computer tested, and critical electrical connections are reworked during remanufacturing at the Philadelphia facility. The process is designed to reduce raw material and energy use compared with producing a new part, while maintaining OE-level fit and function for the listed Chrysler and Dodge applications.
