Already posted about this previously but issue remains.
55 plate Freelander TD4
TC/HDC lights on dash.
Have replaced brake light switch twice.
Checked all earth points around car.
All fuses OK.
Brake lights work.
All connections sprayed with contact cleaner.
Ran a diagnostic on a Topdon ArtiDiag500, showing C1221 Brake Pedal Switch Electrical Failure.
Ran full diagnostic, machine detects when brake pedal is pressed/depressed and when HDC is turned on and off.
Not sure if it's linked to the second plug next to the brake light switch but not sure of it's purpose or what it's called - can't find reference to it anywhere?

Any ideas anyone? I'm scratching my head and it's the only thing stopping an MOT.

Thanks.

Had the same. Can't easily identify the other hall effect sensor. Think it is to disable cruise control but may have other functions. Seems to be fitted whether you have cruise or not.

Like you, I replaced the brake pedal switch and no change.

Have you got the later switch and a short conversion loom? On a 55 plate you may have this already, but I fitted it with the short loom and problem cleared. I think the switch was modified so that it gave a more precise or better timed signal to the ABS that controls the HDC and TC.

Will try and find thread with photos.

New one looks like this.

Got the attached switch, wiring goes to god knows where!

Perfect, just ordered. Thanks for the info. Will let you know if it's worked when it arrives.

OK. They did fit the later one onto the last of the Freelander 1s but you must have missed out.

Hope it sorts you out too.
