CARDONE Remanufactured Electronic and Powertrain Control Modules are designed to meet or exceed O.E. performance. Reverse engineering provides insight into how and why the unit originally failed, allowing our engineers to identify and correct original design weaknesses. All critical components are re-soldered or replaced at our Philadelphia manufacturing plant, and each unit is 100% computer tested to ensure reliability. CARDONE is committed to getting your vehicle back to peak performance.

Features and Benefits:

  • As a remanufactured Original Equipment part, this unit guarantees a perfect vehicle fit.
  • On-car vehicle validation is done to test durability and performance.
  • Our remanufacturing process is earth-friendly, as it reduces the energy and raw material needed to make a new part by 80%.
  • Re-soldering of critical components ensures superior electrical connections. This prevents intermittent failures and leads to longer product life.
  • Tested with automated computer equipment or bench-tested, depending on application, to ensure functionality.

FAA_A1:
ECM stands for Electronic Control Module. PCM stands for Powertrain Control Module. Both the ECM and PCM control the engine; however, the PCM also has control over the transmission.
FAA_A2:
Some GM applications have a knock module that must be transferred to the replacement module. Some older Ford applications have a calibration module that must be transferred to the replacement module.
FAA_A3:
No, not all Ford vehicles require PATS reset. Check the PATS chart found on the O.E. Manufacturers Service site for your application.
FAA_A4:
Ensure that the PCM was properly flash programmed for the vehicle. Also note whether the vehicle is equipped with the Ford "passive anti-theft system", which requires an on-car relearn.
FAA_A5:
Prior to replacing the original ECM/PCM, the installer should determine what caused the original to fail. Common causes of failures are: poor grounds and power, a bad wiring harness and short-circuited solenoids/relays.
FAA_A6:
Yes, most GM vehicles have a VATS, Pass Key or Pass Lock anti-theft system.
FAA_A7:
Not necessarily. There is a 30-minute manual procedure that can be done without a scanner. Refer to your O.E. manufacturers approved service manual for details.
FAA_A8:
Chrysler models 1996 and newer will need to be VIN programmed.
FAA_A9:
Check Engine Light staying on after resetting, engine turning off for no reason, loss of spark, loss of fuel injection, loss of pulse on fuel pump, intermittent starting problems.
