Hi, my name is ***** ***** is usually caused by a bad instrument cluster, the cluster is on the bus system and is a central part of it, have you had this on a scanner and seen if you can comunicate with the instrument cluster?

I can communicate with the PCM, it is the cluster and the modules that are not working that I cannot communicate with
Expert:  Tim Mohr replied 2 months ago.

Hello and welcome to JustAnswer!

There are many possible causes for what you're experiencing and it's going to require some in depth electrical testing; a scan tool capable of communication with all modules is going to be a must. It appears that the CAN IHS bus is down, which could be a failure in any module, a wiring issue, or it may be a failure in a star connector.

It appears you have an actual scan tool?
