Instrument Panel Control Module: Testing and Inspection

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

Procedure

1. HDS DLC - Connection





1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.

2. Turn the ignition switch to ON (II).

3. Make sure the HDS communicates with the vehicle. If it does not communicate, go to the DLC circuit troubleshooting.

2. Rewriting the ODO Data and Transferring the Maintenance MinderTM 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.

* Check the official Honda website for more information on how to write odometer information to a gauge control module that will not communicate with 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 insure that correct battery voltage will be maintained.

Rewriting and Transferring

1. Select GAUGES from the BODY ELECTRICAL SYSTEM SELECT menu with the HDS.

2. Select GAUGE CONTROL MODULE REPLACEMENT (ODO Rewrite) from the ADJUSTMENT menu, and follow the instructions on the display to retrieve the ODO value.

3. Replace the gauge control module.

4. Select GAUGE CONTROL MODULE REPLACEMENT (ODO Rewrite) from the ADJUSTMENT menu, and select READ OUT DATA and save ODO value and Maintenance Minder Data into the HDS.

5. Select WRITE DATA and following the instructions on the HDS display, and install the ODO value and the Maintenance Minder Data into replaced gauge control module. If the data transfer fails, refer to the instructions below to release the locked ODO value.

How to Release Locked Odometer Mileage to the Original Gauge Control Module

If, after you attempt to transfer mileage to a new gauge control module, the odometer display has dashes (---), is garbled, or shows an incorrect value, the original gauge control module can be unlocked and restored to its original state. In this way, it can be used again for additional attempts to transfer the mileage:

1. Confirm that you have the latest HDS version of software.

2. Make sure that the HDS shows the correct VIN for the vehicle you are working on.

3. Turn the ignition switch to LOCK (0), reconnect the original gauge control module.

4. Completely re-boot the HDS.

5. Clear any stored DTCs.

6. Navigate to BODY ELECTRIC/GAUGES/GAUGE CONTROL MODULE REPLACEMENT (ODO REWRITE, etc.).

7. Select 3. RELEASING LOCKED ODO VALUE.

8. Follow the prompts and the odometer mileage will be restored.

9. Start over and make sure the screen prompts are followed.
