Fault ecm 0039

SOURCE: volvo s80 dashboard fault

I recently purchased a 2002 S60 D5 which had this problem. I am not a Volvo expert so don't know if it could be the same fault, but it sounds identical. No lights, gauges etc, but intermittently and very briefly comes on. Having heard some silly prices for replacement dash and ECU, I had a look. I found 4 poor soldered joints on the dash circuit board (top left processor & heat sink). I cleaned them and re-soldered them, although I had continuity just after cleaning the corrosion. The dashboard has worked perfectly since (3 weeks) . If you try this make sure you disconnect the battery first or you may have the SRS airbag warning light on! (I had to have it re-set at the dealers!!)

The whole process took less than an hour. If you are not electronically savvi get one of your mates who is to have a look..

I think that you have a contaminated or bad Mass Air Flow (MAF) sensor. It's located by the engine air filter housing. You can get a used one online for less then 100.

This is a known problem although Volvo will not admit it. The dash needs to come out (10 min job) and sent away for a simple repair. Total cost is about £150 but you will need to get the SRS warning that will be showing in the LED message display cancelled by a Volvo dealer after the dash has come back. Don't try a scrapyard dashboard the ECUs have IP addresses. I used a company in Kent to do the repair. Get onto Google there may be a repairer more local.
