Odometer reads "error"

Hi and thanks for using 2CarPros. Com.

I hate to say it, but there is not a quick fix for this. The odometer will display 'error' if an internal Instrument panel cluster (IPC) memory failure is detected or there is a loss of class 2 communication. Now, the bottom line is there should be a trouble code or codes stored in the computer which directly relate to this issue. A code U1000 indicates a class 2 communication issue. However, there should also be an additional code with it which indicates where the trouble is located. As far as the IPC memory failure, it can be related to the class 2 communication issue or the cluster itself may be bad.

Regardless, the system needs scanned to determine where the problem is originating. Also, an inexpensive scanner will most likely not identify U type codes.

If possible, can you get the computer scanned and let me know what codes are found? That way I can better direct you. Otherwise, it will become a guessing game.

Let me know.

Welcome back.
The only solid black wire to the BCM is for the horn relay circuit. I have attached three pictures for you to look through. It shows the BCM pin connectors, identifies wire colors, and what circuit it's related to.

Let me know if this helps.
