Hill Start assist sticking on

[bongo756]

I have a Mrk 7 350 Jumbo and now and again the hill start assist is starting to stick on. when it enables and I go to drive away, the green light goes off but the brakes are on solid. sometimes I just put the van into reverse and it came off. but today it stuck on for a minute or so before it released. brakes themselves are pretty new, I.e Discs, pads and callipers. Asked a few mechanics and they just shrugged there shoulders. Any ideas out there?

It comes off with the clutch and brake switches I think so you'll need to check them, also maybe recalibrate the longitudinal sensor.

Get codes read if any.

The Management light is on but never checked the codes. will get that checked out tomorrow. Cheers

Hi I have a problem with hill assist as well. It has stopped working several times but I was able to reboot it as per info on this website. This time 'no go'. Any clues what initiates the system?

I am having the same issue. My 2015 Ford Transit 350 XLT is having issues when I am stopped on a hill. If I put the brakes on at a stop sign or light that is on a hill, when I go to take off the brakes stay on, and wont let off, then the hill assist warning comes on and the traction control light. I then have to pull the suction hose out of the big black round brake booster under the hood to release the suction, and I can take off again. I have already changed the brake booster, I have a brand new one installed, and I am still having this issue. Shouldn't the hill start assist release the brakes when I go to take off?

Any help with this would be much appreciated.
Thanks,
Joe

I of live data the clutch pedal switch and calibrate the sas and the longitudinal sensors then do a self test on the abs module.

Any other fault codes that might interfere with the system like faulty brake switch/light /wiring or water ingress etc.

Check the looms near and the bcm and pcm I've seen complaints of water running on top of them.
