Product Details

Cardone’s Engine Control Module line focuses on remanufactured electronic and powertrain control units that are reverse engineered to identify common failure points and correct original design weaknesses. Critical components are re-soldered or replaced at Cardone’s Philadelphia manufacturing plant, and each unit is computer tested to verify operation before release. Part number 79-7813 is a direct-fit ECM for the specified Jeep Grand Cherokee applications and is intended to replace the original module without flash programming.

This part cross-references Jeep OE numbers 56027285 and 56027813 for the same application.

Common Problems This ECM Can Address

• No-start condition caused by a failed engine control module
• Intermittent stalling or rough running tied to ECM failure
• Check engine light concerns related to control-module faults
• Communication or powertrain control issues from a damaged original unit
• Driveability problems after the original ECM has failed electrically

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. Confirm the Ford Engineering ID-style cross-check is not applicable here; for this Jeep application, match the OE number and listed fitment exactly. Because this module is pre-programmed for the listed vehicles, no flash programming is required.

For 1993 Jeep Grand Cherokee, California Emission System, and 1994 Jeep Grand Cherokee applications, confirm the OE number on the original module before installation to ensure correct part selection.

Quality Assurance

Cardone remanufactures this ECM to meet or exceed original equipment performance targets. The unit is 100% computer tested, with critical electrical connections re-soldered or replaced to improve reliability and reduce intermittent failures. The remanufacturing process also reduces raw material and energy use compared with producing a new part.
