Question about 2001 Volvo S80
My question concerned the onboard control modules on my 2001 Volvo S80. We have been having multiple problems with the electrical accessories. The driver’s side door controls would not work, the gas gauge would not read, the trunk would not unlatch, etc… The problem happened twice but in difffrent accessory bundles. Each time our mechanic recommended changing the onboard computer module responsible for those functions. Since we have bought this car used a year and a half ago we have replaced both the major control modules. The other day we had two problems. We had an air bag service message come up, and some of the accessories failed to work. Our mechanic replaced a switch in the steering column for the air bag message and he reset or rebooted the control module, since this was one of the two he had already replaced and he could not find anything wrong with new module. We have had the car back now for about a week and the accessories have failed again. The specific accessories affected are the Gas gauge it reads empty all the time, the trunk release latch won’t open the trunk, although we can open it with the key latch, and the rear doors wont lock remotely or with the driver’s door key. Opening these doors when the others are locked will set off the car alarm.
My question is should our mechanic be looking for a bigger issue a voltage regulator to the control modules, a ground fault, or maybe something like that? Is this a common problem with the S80? Also is there something I can do to reset the control module myself or do I need my mechanics computer interface?
I had a problem with my ambient air temperature sensor and the passenger side door lock. I was told that I needed a control module and that my battery was bad. When I replaced the battery, the module reset and everything started working again. Try disconnecting the positive cable from your battery and or having it checked at a local auto parts store.
