- Critical components are re-soldered or replaced, which helps prevent intermittent failures
- Every unit is 100% computer tested, using automated equipment or bench testing depending on application
- On-car vehicle validation checks durability and performance
- Remanufacturing reduces the energy and raw material needed to make a new part by 80%
Quick facts
- Part: A1 CARDONE 77-8322 engine control module (ecm)
- Fits: 1988-1989 Cadillac Commercial Chassis V8 4.5L and other vehicles
- Condition: Remanufactured
A check engine light that stays on after a reset, an engine that shuts off for no reason or intermittent starting problems can mean the module is failing. Poor grounds and power, a bad wiring harness and short-circuited solenoids or relays can be behind the same signs, so find the cause before buying a replacement.
