Hill assist, pre collision unavailable warning.

Recommended Posts

I have had my car a week, the following warning coming up, Hill assist, pre collision unavailable. Garage that checked codes said too many codes coming up must be battery. See attached. Thoughts?

Hill assist usually points to an abs sensor problem but it doesn’t look like that was scanned in that photo. Forscan should be able to scan everything rather than a generic diagnostics.

It was a full scan the day after having a scan having no codes coming up the day before.

I will put my obd2 reader on it but did not want to remove codes.

If it is an ABS sensor I thought the ABS light on dash would light up?

If that print out is everything then about half of the modules in the car haven’t been scanned. 

The ABS sensor is just one possibility. The ABS module will usually log a fault if hill start is not available but I can’t see it in your print out as having been scanned.

You're using a generic code scanner.

  • It will not read Ford specific DTC's. You need to buy the Ford workshop diagnostic tool, for £2000 ?
  • Or you need to use FORScan and a vLinker FS lead, which will cost around £34

FORScan for Windows (free): https://forscan.org/download.html
