V70 Sunroof Problem

Does anyone know what would cause the
sunroof on a 2001 V70XC to operate eratically?
The switch doesn't seem to be the problem
and a new power module was put in for a
test but that didn't solve the problem
either.

Is there a relay or circuit-breaker in the
system that controls the sunroof? I read
something about a software problem causing
power windows troubles in the V70. Does anyone
know if there is a reset procedure? Thanks.

 

Try this.
Close all of the doors and hood.
Key in pos II engine not running.
Hold both the driver window and passanger
window switches in the driver door panel in the closed or
up position for 5 to 8 seconds after the windows are closed.
Release buttons.
Remove the ignition key.
Operated the remote twice. lock/unlock lock/unlock.
This will reset the UEM brain.
This can correct faulty operation of the sunroof
and/or erratic door lock function.

Using the key in the drivers door to lock/unlock
lock/unlock will also reset the UEM ----
Upper Electronic Module.

Thanks. The procedure worked very well. No
more problems with the sunroof. It goes back
and forth properly.

Thanks! This worked for me too! Very simple, quick and best of all FREE!

 

Good trick on resetting the UEM brain!

 

Hi I have tried this method but did not help operation of my sunroof so wondered if you knew of anything else please. My sunroof will only open about halfway and does not automatically stop at the shut position. I have also tried holding the sunroof button but no luck either. Thanks in advance.
