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

Important: It is not necessary to program a new engine control module (ECM). The ECM is programmed from the factory. Ensure the new ECM is equipped with the latest software/calibration.

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

1. Idle Learn Procedure--Refer to the appropriate procedure:

•	Idle Learn for the 1.4L DOHC engine

•	Idle Learn for the 1.4L SOHC engine

•	Idle Learn for the 1.6L engine

2. The crankshaft position (CKP) System Variation Learn Procedure-- Refer to the appropriate procedure:

•	Crankshaft Position System Variation Learn for the 1.4L DOHC engine

•	Crankshaft Position System Variation Learn for the 1.4L SOHC engine

•	Crankshaft Position System Variation Learn for the 1.5L engine

•	Crankshaft Position System Variation Learn for the 1.6L engine

3. Theft Deterrent--Refer to Programming Theft Deterrent System Components . 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.

If the engine control module (ECM) needs to be reprogrammed, refer to Service Programming System (SPS) .

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