NOTE:

Verify the version of ECM ROM ID before attempting to update the vehicle's ECM software. Refer to the ROM ID Information Table shown above.

CAUTIONS DURING REPROGRAMMING:

1. Make sure the battery has reasonable charge. If the vehicle has been in storage for days run the engine at idle for at least 10 minutes to ensure an
adequate battery charge state for reliable reprogramming results.

2. Perform reprogramming with the ignition key in the ON position.

3. Turn off all lights (Do not leave headlight switch in auto mode) and all accessories (including heater/air conditioner/blower, radio, heated seats, rear
defroster, etc.) to make certain the battery will not be discharged during reprogramming.

4. Be careful not to disconnect any cables connected to the vehicle or the GDS during reprogramming.

5. Do not start the engine during reprogramming.
