Hi, having a problem with my electronic parking brake. I have the orange warning light on constantly. I’ve done a lot of searching around and can’t find an answer
the parking brake was working as should be up until the point I did some work on the car and had the battery disconnected. Once I’d finished and connected the battery again the warning light instantly came up and the parking brake will not work.
I’ve pulled the error codes which are as follow
6031 emergency release detected
6034 actuating unit mechanical fault
now at no point have I performed the emergency release, the parking brake wasn’t stuck on.
then it gets a bit strange. With my scanner if I perform a steering angle sensor reset the parking brake will work as it should and I can hear the actuator unit working but as soon as I turn the car off the handbrake releases and the warning light comes back.
also if I put the car in drive and just let it roll on its own then pull the handbrake switch the handbrake will come on and stop the car but as soon as I release the switch it goes off again (all while the warning light is on still)
this all says to me that mechanically it’s working and it would be more electrical or software problems, although I could be wrong
i have tried a reset (holding brake pedal down then holing parking brake switch up 5secs then down 5 secs) with no joy
ive performed a hard reset of the car (disconnecting battery and holding pos and neg together to drain all power) no joy
checked fuses and all are good
ive cleared the error codes only for them to come back as soon as the car is started
any help would be greatly appreciated
