NOTE:
Obtain a new gauge control module before starting the rewriting process. Only new gauges can be rewritten.
Do not operate anything electrical (headlights, audio system, A/C, power window, door locks etc.) during the 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 vehicle you are working on.
Once you have started this procedure, you must complete it before removing the HDS from the data link connector.
Connect a 12 volt battery charger to insure that the 12 volt battery voltage is maintained during the process.
