Very good information to know!
But it begs the question; if you don't have or own a DRBIII, will any of the other high end scanners be able to perform this "reset" or program the instrument cluster itself? And, does this mean that somewhere in the instrument cluster itself is a memory chip retaining all the pertinent stored programed data or is it simply being fed the information from the associated modules that is on the PCI Bus?
Looking at the wiring diagrams, the Instrument Cluster does have a PCI (data bus) connection which allows it to talk to a multitude of different modules on the PCI network which are controlling many the warning lights and other functions on the instrument cluster itself.
From the FSM: wrote:
The airbag indicator is controlled by a transistor on the instrument cluster circuit board based upon cluster programming and electronic messages received by the cluster from the Airbag Control Module (ACM) over the Programmable Communications Interface (PCI) data bus.
Put this overview drawing together to show the inputs on the PCI Bus to the instrument cluster, there are many.
