AlexandruV Posted April 13, 2021 Share Posted April 13, 2021 Good day fellow Ford owners! My name is Alexandru and I own an Ford Focus Style 1.6 TDCI (MK2 I believe) from 2010. A few days ago after I finished my shift and went out to the car and unlocked it, I realised the boot hasn't unlocked with the car and realised this might be a big problem. After I got into the car, I saw that the interior lights won't turn off automatically, the handbrake symbol won't disappear from the dashboard, the dashboard won't show the outdoor temperature anymore and the red snowflake symbol is always shown on the dash, the green turning lights are not working (including the sound and including hazard/emergency lights only on the dash, the exterior turning lights do work) and also the car won't lock by electric key. When I lock it, it unlocks automatically so I need to lock it mechanically from the inside. The car was absolutely fine up until that day, I took a shortcut to work which I use once or twice a week which is very bumpy for about two minutes and I'm personally guessing (I'm definitely no mechanic) that something moved that's connected to the PCM giving the fact that all of these problems started at once. I tried resetting the car by disconnecting the battery all night, but it did not solve anything. The car is running absolutely fine, the same as before and the problems haven't escalated in the last few days. Would anyone please offer any advice of what to check on the PCM or somewhere else before I take it to a mechanic? I like to try and solve things myself before I take it somewhere else. Hope you're all doing A-okay! Quote Link to comment Share on other sites More sharing options...
MarkRS9 Posted April 13, 2021 Share Posted April 13, 2021 Check the connections on the fuse box in the passenger footwell, as sometimes these get kicked and knocked lose. Also is the battery charged, as a low battery can cause all sorts of electrical issues. 1 Quote Link to comment Share on other sites More sharing options...

unofix Posted April 13, 2021 Share Posted April 13, 2021 My thoughts are it is more a problem with the BCM (Body Control Module) located on/next to the fuse box. There are known problems of water getting in to the connector of the BCM (normally water that has worked its way along the wiring harness back from the screen wash pump). Remove the connector from the BCM and check for signs of water and/or corrosion of the pins. 2 Quote Link to comment Share on other sites More sharing options...

isetta Posted May 16, 2022 Share Posted May 16, 2022 My brother had a mk2 2008 focus. On his car all those problems were caused by one plug on the underneath of of the bcm / fuse box underneath the glove box. Unplugging and plugging them back in cured it. I can’t tell you which one of the multiple plugs it was. Quote Link to comment Share on other sites More sharing options...

Well I would guess after a year he either found an answer or scrapped the car. What is a Ford Model 2007 ? Quote Link to comment Share on other sites More sharing options...
