For 1990-2009 cars only

The following service procedures require either a programming or a setup event performed for a complete repair.

ECM Replacement and Reprogramming

If the engine control module (ECM) is replaced or reprogrammed, the following procedures must be performed:

  1. ECM Reprogramming--Refer to Service Programming System (SPS).
  2. Idle Learn Procedure--Refer to Idle Learn for the 2.4L engine or Throttle Learn for the 3.2L engine.
  3. Fuel Injection Programming--Refer to Fuel Injector Flow Rate Programming for the 2.0L diesel engine.
  4. Pilot Injection Reset--Use a scan tool to reset the injection values for the 2.0L diesel engine.
  5. DPF Reset Replace ECM--Use a scan tool to reset the DPF system for the 2.0L diesel engine.
  6. Theft Deterrent--Refer to Theft Deterrent Control Module Programming and Setup. The ECM will learn the incoming fuel continue password immediately upon receipt of a password message. Once a password message is received, and a password is learned, a learn procedure must be performed to change this password again. An ECM which has been previously installed in another vehicle will have learned the other vehicle's fuel continue password, and will require a learn procedure after programming to learn the current vehicle's password.
  7. Engine Oil Life Remaining--When available, use a scan tool to reset the Engine Oil Life Remaining back to the original percentage recorded before the module was replaced.

Setup for Component Replacement

The replacement of some components will require a setup procedure for complete repair.

2.4L and 3.2L

If the throttle body or the ECM is replaced, an Idle Learn Procedure must be performed. Refer to Idle Learn for the 2.4L engine or Throttle Learn for the 3.2L engine.

2.0L Diesel

    • If the DPF pressure sensor, the DPF, injectors, or the ECM is replaced, you must reset the DPF system with a scan tool.
    • If an injector is replaced, the following must be perform:
       -  The fuel injectors must be programmed. Refer to Fuel Injector Flow Rate Programming.
       - The Pilot Injection values must be reset with a scan tool.
       - The DFP system must be reset with a scan tool.
