Release Locked odometer mileage to the
original gauge control module.
22-276 Gauges
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 M odule 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. Electric/Gauges/Adjustment/Instrument Panel
Replacement.
7. Select ‘‘3. Releasing Locked ODO Data’’.
8. Follow the prompts and the Odometer mileage will be restored.
9. Start over and make sure the screen prompts are followed.

disconnect the connectors.
2. Remove the two screws and the dash lights brightness controller and odometer select/reset
switch (A).
3. Check for continuity between the terminals in each switch position according the table.
4. If the continuity is not as specified, replace the dash lights brightness controller and odometer select/
reset switch.
5. Install the dash lights brightness controller and odometer select/reset switch in the r everse order of
removal.
