Focus c-max 2003 gem modul problem
Hi Mates!

Could You help me in the following problem?:
2003 focus cmax 2.0d, after central lock, then 4-5 minutes, the indicator lights flashing shortly and the windscreen wipers move 8-10 centimetres. And again until opening.
Somebody any advise, please?
I didn't seen any extra alarm system or wiring.

Thank You

Sounds like a BCM fault or grounding issue at BCM (this generation uses lots of switched grounds). Also check battery saver relay/circuit. I'd start first with battery saver then move to BCM wiring.

Hi,

You know exactly, which is the battery saver relay? I hear click noise from the fuse plate, inside, when the wipers running. Maybe the ground lost? Also have a P0101 fault, also possibility ground problem.

P0101 is a Mass Air Flow code, probably unrelated.

Battery saver relay is inside the car behind the dash (see attached schematic). I'd be making sure there are no corroded grounds at the GEM and CEM (water damage as the above mentioned). Either water damaged BCM or poor contact grounds.
