 Subject: 2001 Dakota 5.9L Instrument Cluster Problem
IP: Logged
Message:
I'm hoping someone will be able to help me with this problem. The truck starts fine, but instrument panel completely dies and guages zero out when I release the emergency brake. When emergency brake is engaged, guages work, but all MIL lights are always on. I ran scan on truck and DTC code thrown ia P1687 which makes sense. I then proceded to run EMIC test and it threw codes: 920,921,940,960,999. These codes suggest that the PCM and TCM aren't sending information to the EMIC. Just my guess. Sometimes odometer will read "NO BUS" after the scan. Can anyone offer me any suggestions? I've checked cluster fuse and its ok. I'd hate to start replacing expensive control modules and the problem could be a simple ignition switch. Any advice would be appreciated.

I forgot to mention the security light is the only thing that will stay on when I release the emergency brake, all other guages an MILS die. I traced in wiring diagrams and emergency brake enganged grounds VTSS inside CTM, which in turn must communicate with with the instrument cluster. I'm not good at reading wire diagrams and don't know how to interpret this information, but it might help some of you experts to diagnose the problem.
