2002 S60. Central locking and gas gauge issues.

[Yaworski]

Update the whole thing . . . . this is the email that I sent to my mechanic this morning. Anyone have any thoughts?

------------------

This all started around the time that you discovered the leaking fuel pump
so it might be related but, then again, it might not.

Bear with me as this gets involved.

The first thing that I noticed was that the trunk would unlock itself
while I was driving. I'd get an alert on the dash that that the trunk was
open. Sure enough, when I stopped, the trunk would be open. I started
checking the trunk before I got into the car and the locked trunk would
unlock after a couple minutes.

Then I started getting an intermittent warning that a bulb for a position
light had failed. It would come on for a second, go away, and come back.

Next I noticed that the rear doors were not locking or unlocking
consistently with either the fob or the door button. They'd lock and
unlock maybe one out of ten times. Also, when the rear doors wouldn't
unlock, the trunk lid switch would not open the trunk.

Then the fuel gauge started to act wonky. I first noticed that it
wouldn't show the fuel level for a few seconds after turning the car on.
Then it would shut off and go to empty after a few seconds, not even the
low fuel light would be on. The other instruments, including the clock
seem to work fine.

I foolishly thought, "Maybe I am low on gas" and went to add some. The
gas door would not open with the button on the dash so I had to open it
manually from inside the trunk. It turned out that the tank was almost
full.

you might try a new battery in the fob.
at least its cheap.

Not likely the fob battery because the door locks don't respond to the door button.

inspect the CEM for water damage then.

Where is the CEM and is it in the same spot as an 02 V70 XC?

Thanks, this one is the shortest and simplest. Will look at the other videos then check the cowl area and CEM.

Does the CEM control the fuel guage too?

ETA: From what I can find online, the CEM is under the dash in my car. How would that get wet if I don't have other indications of water leakage like wet carpets?

Is it in the same location for a 2002 S60?
