Rewriting the ODO Data and Transferring the Maintenance Minder(TM) Data to a New Gauge Control Module

NOTE:

- Obtain a new gauge control module before starting the rewriting process. Only new gauges can be rewritten.
- Rewriting is not possible on a gauge control module that will not communicate with the HDS.
- Make sure that the HDS shows the correct VIN for the vehicle you are working on.
- Once you have started this procedure, you must complete it before removing the HDS from the DLC.
- Connect a jumper battery (do not connect a battery charger) to ensure that correct battery voltage will be maintained.
- Check any official Honda service website for more service information about the odometer.
