Engine Control Module Programming and Setup



ENGINE CONTROL MODULE PROGRAMMING AND SETUP

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

ECM Replacement
If the engine control module (ECM) is replaced, the following procedures must be performed:
1. ECM Reprogramming-Refer to PSD SIE TITLE Error: SIE linked to empty Cell ID 71878.
2. Idle Learn Procedure-Refer to the appropriate procedure:
- Idle Learn Procedure for the 1.2L engine
- Idle Learn Procedure for the 1.4L DOHC engine
- Idle Learn Procedure for the 1.4L SOHC engine
- Idle Learn Procedure for the 1.5L engine
- Idle Learn Procedure for the 1.6L (L91) engine
3. The crankshaft position (CKP) System Variation Learn Procedure- Refer to the appropriate procedure:
- CKP System Variation Learn Procedure for the 1.4L DOHC engine
- CKP System Variation Learn Procedure for the 1.4L SOHC engine
CKP System Variation Learn Procedure for the 1.5L engine
- CKP System Variation Learn Procedure for the 1.6L (L91) engine
4. Theft Deterrent-Refer to Programming Theft Deterrent System Components (Scan 100) Programming Theft Deterrent System Components (Tech 2). 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.

ECM Reprogramming
If the engine control module (ECM) needs to be reprogrammed, refer to PSD SIE TITLE Error: SIE linked to empty Cell ID 71878.

Setup for Component Replacement
The replacement of some components will require a setup procedure for complete repair.
- If any of the following components are replaced, an Idle Learn Procedure must be performed. Refer to the appropriate procedure:
- Idle Learn Procedure for the 1.2L engine
- Idle Learn Procedure for the 1.4L DOHC engine
- Idle Learn Procedure for the 1.4L SOHC engine
- Idle Learn Procedure for the 1.5L engine
- Idle Learn Procedure for the 1.6L (L91) engine
- Throttle body assembly
- ECM
- If any of the following components are replaced, a CKP Variation Learn Procedure must be performed. Refer to the appropriate procedure:
- CKP System Variation Learn Procedure for the 1.4L DOHC engine
- CKP System Variation Learn Procedure for the 1.4L SOHC engine
- CKP System Variation Learn Procedure for the 1.5L engine
- CKP System Variation Learn Procedure for the 1.6L (L91) engine
- CKP sensor
- Engine replacement
- Any engine repair that disturbs the relationship between CKP sensor and the crankshaft reluctor wheel.
