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). When replacing an ECM, the VIN must be programmed in the ECM. If there is no VIN in ECM 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, SEDONA 3.5L V6).

2. Select "VIN WRITING".

3. Check the ECM status.

NOTE:
- VIRGIN: VIN is not programmed
- LEARNT: VIN has been already programmed

Is the ECM 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, then back ON.

7. Verify the programmed VIN in the ECM memory.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.

• You are not confident in the next step or safety outcome.
