2002 S80 - Loss of Dashboard Functions

mudcat · Post by **mudcat** » 23 Jun 2007, 19:15

I have lost all dashboard functions: fuel, tempertature, tach, speedometer are all dark. Prior to this I had a SRS error code on the screen.

I hope this doesn't have anything to to with the ECM.

Any help is appreciated.

Just sold my V70, with 144k. I knew that was a bad idea.

Did you check the fuse? I've reseated fuses on my dad's S80 to clear up a "limp home" mode the car went into.

Checked all fuses, pulled the ones associated with the dash, and ecm, and nothing. I also replaced the battery becuase when I went to check the water, it was really low. A battery test showed a real low charge and it was 5 years old.

I am having the same problem but my drivers side window and locks will not work either. Are you still having the problem?

This has become an intermittant problem. The dashboard has not worked at all when I drove to work the past two days, however, when I go out at lunchtime and drove it, the dash functioned normally. Both days, the car has been sitting in the hot sun.

This has to be a power supply problem to the dash.

I am going to try the dealer first, but I am not real confident with these guys for a intermitant problem. I need to get a wiring diagram so I can start hunting for a loose terminal.

well mine is at the volvo dealer i waited about a hour and a half and they were not able to find anything so they gave me a loaner and said it might take them a day or so to figure it out.

Dealer diagnosed the problem as dim module. Dealer quoted $850 for a new part. I found a used dim from an independent volvo parts guy for $65. I will let you know if the used part works.

Thank God for the internet.

Just like mudcat my car was sitting under the sun and very hot. I took the car to the dealer and they told me that they needed to update the ecm software due to a clitch that will cause the problem. I paid 118.00 for the software update. I think they are hoping it will fix the problem. I will update after a month.

Did changing the dim module fixed the issue?
