That was deffo a bad sensor/ dirty pickup ring issue
Recently, I had the dash out for welding so disconnected the ECU and ABS ECU and when I've put it all together the orange light comes on with the ignition and stays on, but the pump fires up as required.
The red light goes out when the handbrake is released.
While I was working in the garage with the car in pieces I noticed that occasionally the ABS pump would come on even with no key in the ignition.
Any help gratefully received....
What car is it? There are ABS fuses and relays in the passenger footwell (right hand side). I've got the wiring diagrams if you can tell me what motor it is.
