Re: more problems with the instrument cluster

I have read that there is a digital three-way "marriage" that happens on the assembly line, between the instrument cluster, the PCM, and the anti-theft sensor that wraps around the key tumbler. At this point in time, the key-code is established ... all "on-board". Apparently, after this time ... if any of the three components is changed out, or damaged, it takes a dealership intervention with a special electronic tool to "marry" things back again.

(I'm telling you much more than I know!)
