Hi all,
I'm new to the Focus world. I had an interesting fault occur last night that I thought I would hare with the community. I have a 2010 TDCI LV Focus Manual with 53k km on the clock. I hooked up a trailer last night for the first time and did a light check. All lights checked ok with the ignition on. I turned the ignition off and pushed the brake pedal again. My father was checking the lights for me on the trailer and commented that it didnt seem right. I pushed them again and then figured it was just a qwerk with the car. Drove home the 2km without a problem. When pulling into the driveway the dashboard lit up with a Engine Malfunction fault. I couldn't do anything about it as my OBD reader had stopped working. This morning I went and picked up another reader and on the way to Jaycar the car went into limp mode. When I scanned for faults it came back with a P0504 'Powertrain' fault. I researched and it is linked to a generic OBD fault for the brake switch. I figured it was linked to putting the brakes on with a trailer attached while the car's ignition wasn't on. Hope this helps anyone who come across a similar issue. Cheers Jason |

Does this mean the trailer wiring needed a special module fitted so the car computer did not register a fault on current draw?

The car came with a factory fitted module that looks dealer fitted. Thats why I thought it was all a bit odd.
