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

NOTE:

• Obtain a new gauge control module before starting

the rewriting process.

• 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

car you are working on.

• One you have started this procedure, you must

complete it before removing the HDS from the DLC.

• Connect a battery jump box (not a Battery charger) to

insure that correct battery voltage will be maintained.

1. Before replacing the gauge control module,

connect the HDS.

2. Select GAUGES from the BODY ELECTRICAL menu

display.

3. Select ‘‘Gauge Control Module Replacement (ODO

rewrite)’’ from the ADJUSTMENT menu, and follow
the instructions on the display to retrieve the ODO
data and the Maintenance Minder information.

4. Replace the gauge control module.

5. Follow the instructions on the display to write the

new ODO data and Maintenance Minder data to a
new gauge control module. If the data transfer fails,
refer to the instructions below to release the locked
ODO data.

If after you attempt to transfer mileage the odometer
has dashes (

), garbled, or incorrect value

displayed, do the following start over. The original
gauge control module is going to be unlocked and
restored to its original state.

1. Confirm that you have the latest HDS version of

software.

2. Make sure that the HDS shows the correct VIN for

the car you are working on.

3. With the ignition switch to LOCK (0), reconnect the

original gauge assembly.

4. Completely re-boot the HDS.

5. Clear any stored DTCs.

6. Navigation to Body.
