REVISION SUMMARY
*Under REPAIR PROCEDURE, information was changed.*
SYMPTOM
The immobilizer system can't be rewritten after replacing the ECM/PCM or the immobilizer-keyless control unit.
POSSIBLE CAUSE
The gauge control module (tachometer) does not contain the supporting data for immobilizer reprogramming that allows you to rewrite it.
VEHICLES AFFECTED
CORRECTIVE ACTION
Replace the gauge control module (tachometer) if you replace the ECM/PCM or the immobilizer-keyless control unit.
NOTE:
You must transfer the odometer mileage from the old gauge control module to the new gauge control module.
PARTS INFORMATION
NOTE:
Because ECM/PCM and immobilizer-keyless control unit replacements are rare, it is not necessary to stock the gauge control module (tach).

REPAIR PROCEDURE
NOTE:
^ When replacing the ECM/PCM, immobilizer programming is a portion of the ECM/PCM replacement. For the complete replacement procedure, go online, enter keyword ECM REPLACE, and select the appropriate ECM/PCM Replacement procedure.
^ When replacing the immobilizer-keyless control unit, you need all the customer's keys.
*^ A PCM code is required.
NOTE:
If you cannot log in to the Interactive Network (iN) screen on the HDS, you must retrieve the PCM Code from the Immobilizer Code Inquiry in the iN.*
^ Once the HDS retrieves the ODO data from the gauge control module, the ODO value on the LCD displays "-" making the ODO function unusable. The HDS holds only one ODO value at any time in its memory.
^ Get the new gauge control module before doing the rewriting procedure.
*1. Connect the HDS to the DLC (data link connector).
2. Log in to the iN screen.*
3. Select Gauges from the BODY ELECTRICAL menu display.
4. Select Gauge Control Module Replacement (ODO rewrite) from the ADJUSTMENT menu, and follow the on-screen instructions to retrieve the ODO value.
5. Adjust the steering column upward.
6. Gently pull out the lower edge of the dashboard lower cover to detach the lower clips.
7. Detach the upper clips, and release the hook and pin by pulling back on the dashboard lower cover.
8. Tilt the steering column down, and extend the telescoping column to its limit.
9. Remove the screw from the bottom of the subdisplay visor.
10. Place your hand at the back of the switch panel, then gently pull from the driver's lower cover opening to release the clips and the hook.
11. Pry up on the inside edge of the subdisplay visor with a trim tool to detach the clip and release the pin.
12. Detach the clips along the upper edge of the subdisplay visor, then gently pull out the visor to release the hooks.
13. Disconnect the illumination control switch connector and the power mirror switch connector.
14. Remove the three screws from the gauge control module.
15. Disconnect the 36P connector from the gauge control module.
16. Install the new gauge control module in the reverse order of removal.
17. Follow the instructions on the HDS display to write the ODO value to the new gauge control module.
