My 2010 V50 (and I assume the rest of the C30, C70, S40… so-called “P1” cars) has an “Alarm System Service Required” message on the DIM, and VIDA reported “CEM-DD1B – Communication with SCM control module Signal missing” (SCM = Siren Control Module).
But SURPRISE! The siren is not up above the passenger-side wheel well (alternatively “behind the passenger-side headlight”) as it has been for the v70s and other “P2” pre-Ford cars.
So, here’s the process, as it is not documented anywhere, and I do not have the time to make a video for YouTube (nor the delusion to think that I can make spare change from YouTube).
It’s still on the passenger side, but its just below and in front of the windshield. To get at it, you will remove the cowl:
- Pop out the plastic clips circled in red in the photo above by pressing in the center until it slightly detents, then get under the large lip with a fork of a “plastic crowbar” interior tool, and lift up the whole thing. (I replaced mine with slightly more sensible ones from the specialty fastener drawer at Lowes – 1/4-inch size, as mine were broken when the previous owner opened it up, but did not repair anything.)
- Next turn the plastic Phillips-head screws (red squares) 1/4 turn to the left (from noon to 9am) but do not remove them.
- Then pop off the plastic covers on the wiper pivot points (yellow circles), and remove the nuts that hold the wiper arms on.
- Lift up the wiper a bit, and wiggle the part of the arm that did not bend up with the wiper blade, and the wiper arm will come off easily. (Gotta take the tension off that is holding the wiper blade against the glass.)
- Now gently wiggle the entire plastic cowl away, helping it to come free of the area around the hood hinges.
