ECM ROM ID INFORMATION

Cautions during ECM update:

1. Make sure the vehicle's battery has reasonable charge. If the vehicle has been in storage for days, run the engine to ensure an adequate battery charge state for reliable update results.

2. Turn off all lamps (do not leave head lamp switch in auto mode) and all accessories (including heater, A/C, blower, radio, seat warmer, defroster, etc.) to prevent battery discharge during the update.

3. Perform update with the ignition switch in the ON position.

4. Be careful not to disconnect any cables connected to the vehicle or scan tool during update.

5. Do not start the engine during update.

6. Do not turn off the ignition switch during update.
