ECM Replacement

The following procedures are required if the Engine Control Module (ECM) must be replaced.

  1. ECM reprogramming, see SERVICE PROGRAMMING SYSTEM (SPS) .
  2. Theft protection, see Electronic Immobilizer Component Programming. ECM immediately learns the incoming password for continued fuel supply upon receipt of a password message. Once the password message has been received and a password has been learned, a programming (learning) procedure must be performed to change the password. An ECM that was previously installed in another car learned that car's password for continued fuel supply and will require a programming (learning) procedure after programming to learn the new car's password.
  3. Throttle programming procedure, see THROTTLE/IDLE PROGRAMMING .
  4. Engine oil's remaining service life - If available, use a scan tool to reset the engine oil's remaining service life to the original percentage that was registered before the unit was replaced.
  5. Transmission fluid's remaining service life - If available, use a scan tool to reset the transmission fluid's remaining service life to the original percentage that was registered before the unit was replaced.
  6. Crankshaft variation programming, see Crankshaft Position Sensor System, Variation, Programming.
  7. Clutch Pedal Position Sensor Programming, see Clutch Pedal Position Sensor Programming.
