DESCRIPTION:

The REM may not "wake-up" when unlocking a vehicle. When the REM is
locked-up, the REM functions will not operate. REM functions which are
affected include: REM communication, rear door central locking function,
remote trunk lid lock function, fuel lid lock function, rear wiper/washer
function, fuel gauge value. DTC CEM-1A5A will also be set.

The above listed functions will return if the REM fuse 1 is removed and
re-installed.

NOTE: Using the remote vehicle key will allow the operator to unlock/lock
the front door and allow unlocking/locking of the trunk assembly.

SERVICE:

If the above description is consistent with a customer complaint, Reload of
the

complete REM system is needed. The software is updated so the REM does not

go to sleep again.

 

I had exactly this with my V70 2,4T -01. After updating the software, I
have never experienced any more problems related to doors or fuel cauge
etc. It cost me a whopping 14 euro cents! (Actually Volvo Germany paid
for that!)
