Hello,

I have a 2002 S80. about two months ago, the clock on the dashboard didn't function well and ran constantly fast. About a month ago, the dashboard was totally down and there is no light at all on dashboard except that the engine check light is on.

I bought another DIM to replace the current one, and it had the same problems. When I re-installed the old one (the one was on my car), the light was up again when I started my car, and then the light went off after I turned off engine and restarted it again.

I used a diagnosis tool to read messages on the car, and it shows 'CEM-1A56 Communication with DIM'.

Any ideas on what is going on will be appreciated.

Thanks

Michael
