Honda HR-V: Rewriting The ODO Data And Transferring The Service Reminder System Data To A New Gauge Control Module

Procedure

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 insure that correct 12 volt battery voltage will be maintained.
