You're welcome mate.

Yeah It looks very basic but works pretty good.
Good luck.

VQ304, if by chance you have recently changed to a staggered tyre set on the car this might be your issue (say, the rear is taller than the front). Although I doubt these ecu's were that advanced back then and this might only be a later vehicle thing. Even a single low tyre pressure can trigger the light on some vehicles.
Or holding the front brake on your motorbike and smoking the rear before your run down the strip will throw the light - had that before and needed to clear code after every run, lol

Going off that diagram it's a basic system with no diagnostic codes which surprises me.

Deuce i know new cars are very fussy like that with miss matched tyre sizes etc
But i have been running 195 60 15 fronts and 255 60 15 rears for over 1 year now no worries
I checked the sensor gaps tonight they are a little larger than whats recommended tho pulling one shim outa rear end sensor and the gap become way to close/ tight.

I cleaned the front sensors and ring, with some cleaner and blew the crap outa them with the compressor. Will drive the car tonight and see how i go.

I would go back to checking electrical connections and plugs etc.
Or re-inspect the wiring in the wheel arches etc for possible stone damage.

Silly question. But have you fitted LED brake light globes to it recently?

All good. Read somewhere recently that someone fitted cheap led globes to their VR and it caused havoc with abs and cruise control.
