Engine Control Module: Service and Repair

VIN PROGRAMMING PROCEDURE

VIN (Vehicle Identification Number) is a number that has the vehicle's information (Maker, Vehicle Type, Vehicle Line/Series. Body Type, Engine Type, Transmission Type, Model Year, Plant Location and so forth. For more information, please refer to the group "GI" in this SERVICE MANUAL). When replacing a PCM, the VIN must be programmed in the PCM. If there is no VIN in PCM memory, the fault code (DTC P0630) is set.

CAUTION: The programmed VIN cannot be changed. When writing the VIN, confirm the VIN carefully

1. Select "Vehicle" and "Engine" (For example, TUCSON 2.0L L4).









2. Select "VIN WRITING".






3. Check the PCM status.






NOTE:
- VIRGIN: VIN is not programmed
- LEARNT: VIN has been already programmed Is the PCM status "VIRGIN"?

YES : Go to next step 4.

NO : END

4. Write the VIN with cursor, function and number keys.

WARNING: Before pressing the "ENTER" key, confirm the VIN again because the programmed VIN cannot be changed.






5. After verifying the written VIN, press the "ENTER" key.
6. Turn the ignition switch OFF, and then turn ON.
