Correction

Important
In order to select the correct calibration on some vehicles, you must first identify the cluster part number. This can be done using the Tech 2. DO NOT REMOVE THE CLUSTER.

A new service calibration has been released to correct these conditions. Reprogram the PCM using the new service calibration, which was available from Techline starting August 25, 2003 on the TIS2000 version 9.0 or later. This calibration is an electronic calibration and is not available from GMSPO.

Will the dealer do this fix no-charge if out of warranty?

I don't think they will, but depends on your dealer.

Unless you have a tech 2 and the latest updates of GM's TIS program, you won't be able to do this fix without the dealer. It would probably only cost a half hour labour for the reflash if you don;t have warranty.
