Volvo Ecu problem Urgent - Poloman - 17-07-2014
Hi guys, I have a costumer's Volvo 823 ecu. The problem is that suddenly it turns off. If he starts the car it continuous until 20-30 min time and it turns off again. And all the time it turns off-on-some time-off...
Can you please suggest me what can be the cause of problem? For sure it is ecu fault but I cannot identify what it can be happened.
Thank you for your time. The problem is urgent as the truck has been stopped and it needs to continue for journey.

If this ECU fault in hardware inside, you need to open it and check,but it is so hard. and i suggestion you can reprogram this ECU first by software, maybe it just fault in software program

best bet would have been to get the ecu tested by someone like alliance electronics. If its a hardware fault you get a guaranteed fix and if its a software fault you get a proper diagnosis for a reasonable price.
