multidisplay MULTIDISPLAY SHOWS FAULT DIAGNOS TOOL NO FAULT

[bohaboha]

I have a strange problem with my Peugoet 307 sw 2007 Multidisplay shows ABS fault and the light is on on the dash board but at 3 workshops and different diagnostic tools no error when scanning however none had Diagbox.
I can't tell which sensor front or back right or left is faulty if someone has had the same problem or what can be done.Thankful for all suggestions

If there was an issue with the wheel speed sensor, then Diagbox would tell you which one it was.

I can't answer for the other diagnostic tools.

Are your brake lights working correctly? I have had this issue in the past on older PSA vehicles where someone has fitted the wrong type of bulb in the brake lights & caused the ABS light to be on with no fault codes logged.
Just to confirm can the garage can actually connect to the ABS unit but just showing no fault codes? can they read live data from the wheel speed sensors & brake switches?

Thank you both for your answers. I understand that you do not comment on any other Diagnostic tools but I am concerned that the error is on display. I have to look for someone who has Diagbox.
No, I don't have a problem with the brake light because they have worked and they haven't been replaced. But it is said that it may have to do with the brake pedal has read no longer know where.
