2001 S60 Upper Electronics Unresponsive

[andrewbryan12]

Hey guys,

I was driving home from a camping trip this weekend with my sunroof open, and when I finally got home all of my upper electronics were completely dead! Not to mention my sunroof was stuck open. I have had this sunroof issue before, and it only required me pressing the unlock button on my remote 3 times. In the past, that little trick reset some module and I was back in business. Not this time though; my remote is completely unresponsive.

I went to RadioShack later that day and replaced the battery, no luck. Do I need to resync the remote with my car somehow?

I tried the unlock trick mentioned above with my key, no luck.

I checked for a blown fuse, no luck.

Reset my car battery with key in position II, no luck.

Tried odometer reset/key position II trick, no luck.

I tried setting the alarm off by opening a door when the system was armed, this only resulted in flashing lights and no horn.

Someone please HELP!

While the battery is disconnected and key is in Pos II touch the postive to negative lead to fully discharge the modules or press the brake pedal to do the same, then reset the negative battery terminal with key in PosII. Try that and see if it helps.
