- If VCM was replaced, the EEPROM in the VCM must be programmed. If EEPROM is not programmed, a DTC will be set.
- Ensure battery is fully charged. Ensure cable is properly connected on Data Link Connector (DLC). Turn ignition switch to ON position. Perform EEPROM programming using Techline® equipment. Follow manufacturer's instructions and latest software applicable for vehicle model.
- Once EEPROM is reprogrammed, CKP sensor variation learn procedure and password learn procedure for anti-theft system must be performed. See CRANKSHAFT POSITION (CKP) SENSOR VARIATION LEARN PROCEDURE . See PASSWORD LEARN PROCEDURE FOR ANTI-THEFT SYSTEM .NOTE: If EEPROM programming fails, ensure all harness connections on VCM are okay. Check Techline® for latest software. If EEPROM programming still fails, replace VCM.
- Once CKP sensor variation learn procedure and password learn procedure for anti-theft system are performed, perform Powertrain On-Board Diagnostic (OBD) system check. See POWERTRAIN ON-BOARD DIAGNOSTIC (OBD) SYSTEM CHECK in appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
