A1 CARDONE 79-1638V engine control module (ecm) for the 2000 Jeep Grand Cherokee 6-cylinder 4.0L is a remanufactured computer that controls the engine.
- Reverse engineering shows how and why the original unit failed, so engineers can identify and correct original design weaknesses
- Critical components are re-soldered or replaced to renew electrical connections and help prevent intermittent failures
- Every unit is 100% computer tested, using automated computer equipment or a bench test depending on application
- On-car vehicle validation tests durability and performance
- Remanufacturing reduces the energy and raw material needed to make a new part by 80%
Quick facts

A check engine light that stays on after a reset, an engine that shuts off for no reason, loss of spark or intermittent starting problems can point to a failing engine control module. Before you replace it, rule out poor grounds and power, a bad wiring harness and short-circuited solenoids or relays, which are common causes of ECM failures.
