Verify vehicle application by using underhood Emission Control label.ģ.Once EEPROM is reprogrammed, use the Scan Tool to reset Idle Air Control (IAC) valve. DO NOT perform CKP sensor variation learn procedure on Calif. NOTE: Crankshaft Position (CKP) sensor variation learn procedure should ONLY be performed on Except Calif. If EEPROM is not programmed, a Diagnostic Trouble Code (DTC) will be set in the VCM. If EEPROM programming still fails, replace VCM.ģ.Once EEPROM is reprogrammed, Crankshaft Position (CKP) sensor variation learn procedure and password learn procedure for anti-theft system must be performed using proper procedure.Ĥ.Once Crankshaft Position (CKP) sensor variation learn procedure and password learn procedure for anti-theft system are performed, perform powertrain On-Board Diagnostic (OBD) system check.Įlectronically Erasable Programmable Read Only Memory (EEPROM) Programming (7.4L)ġ.If Vehicle Control Module (VCM) was replaced, the EEPROM in the VCM must be programmed. NOTE: If EEPROM programming fails, ensure all electrical connections on VCM are okay. Perform EEPROM programming using the Techline equipment manufacturer’s instructions and latest software applicable for the vehicle model. Ensure cable at Data Link Connector (DLC) and the SPS Device are properly connected. If EEPROM is not programmed, a Diagnostic Trouble Code (DTC) will be set in the VCM.Ģ.Ensure battery is fully charged. California emissions may be available in other states.Įlectronically Erasable Programmable Read Only Memory (EEPROM) Programming (4.3L, 5.0L & 5.7L)ġ.If Vehicle Control Module (VCM) was replaced, the EEPPOM in the VCM must be programmed. NOTE: References to California models apply to California emission vehicles, which may be verified by underhood Emission Control label. NOTE: Read all procedures listed to determine why and when each procedure is to be performed before proceeding. (1) – Vehicle series is fifth character of VIN. 4WD Blazer, Bravada, Jimmy, Pickup & Sonoma
