Gauge Control Module Removal and Installation

NOTE: Before replacing the gauge control module, retrieve the ODO data from the gauge control module with the HDS.

1. Gauge Control Module - Retrieve

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 (DLC).
Connect a 12 volt jumper battery (do not connect a 12 volt battery charger) to ensure that correct battery voltage will be maintained.
