NOTE: If you are troubleshooting multiple DTCs, be
sure to follow the instructions in B-CAN System
Diagnosis Test Mode A (see page 22-93).
1. Clear the DTCs using the HDS.
2. Turn the ignition switch to LOCK (0), and then back to ON (II).
3. Start and run the engine for at least 5 seconds then turn the engine off.
4. Check for DTCs with the HDS.
Go to step 5.
Intermittent failure, the F-CAN
communication line is OK at this time. Check for
loose or poor connections. If the connections are
good, check the battery condition (see page 22-67),
and the charging system.
5. Check for DTCs in the ECM/PCM or ABS/VSA.
Troubleshoot the ECM/PCM or ABS/VSA.
Go to step 6. 6. Do the Gauge Control Module (Tach) Input Test
(see page 22-271).
Go to step 7.
Repair the faulty input then recheck for
DTCs.
7. Substitute a known-good gauge control module (tach).
8. Clear the DTCs with the HDS.
9. Turn the ignition switch to LOCK (0), and then back to ON (II).
10. Start and run the engine for at least 5 seconds then turn the engine off.
11. Check for DTCs with the HDS.
Substitute a known-good ECM/PCM and
retest. If the system/indication goes away, replace
the original ECM/PCM.
The original gauge control module (tach) is
faulty; replace the gauge control module (tach)
(see page 22-277).

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.

Resetting the Moonroof Control Unit
Resetting the moonroof is required when any of the following have occurred: The moonroof was moved manually while the battery was dead or disconnected.
 The moonroof motor was replaced with a new one.
 Any of components related to the moonroof were replaced. – Wind deflector
– Moonroof glass
– Moonroof seal
– Moonroof glass bracket
– Moonroof cables, etc.
To reset the moonroof control unit, do these steps: 1. Close the driver’s door, and keep it closed until the procedure is complete.
2. Turn the ignition switch to LOCK (0).
3. Press and hold the tilt switch, and turn the ignition switch to ON (II).
4. Release the tilt switch, and turn the ignition switch to LOCK (0).
5. Repeat steps 3 and 4 four times.
6. Press and hold the moonroof open switch for 3 additional seconds after the moonroof is fully opened.
