Abs light, bleeding?

[womble3go]

Hi all,
Ive just done some work on my hydraulic system, changed the FDV and regulator had all 5 spheres off and checked and cleaned the tank and fillters and the oil.

The car seams to working as it should, but do have the ABS light on tried the normal things that sort it with no luck? Do I need to bleed the brake system? or is there some thing else Ive missed.

Kevin.

It’ll probably be a coincidental sensor fault. Perhaps you disturbed the wiring to one of the rear sensors when removing the rear spheres? There’s an ABS fault finding thread on here somewhere if you search the faq. Got a multimeter? (You’ll need one)

I Do have a spare sensor that I have tried on the o/s one were I changed the cambelt but was thinking about trying the others just to be sure. Have cased sensor faults before, got there in the end.

Often it’s not the sensor but the wiring that goes open circuit, particularly over the rear arms as that’s the bit that gets the most flexing (and crud) over the years

You can plug in your spare sensor to all the the loom connectors one by one for static testing. The rear ones are under the back seat. The fronts you have already found.
It might be worth measuring the resistance of your spare one to ensure it is functional. Look for about 1000 ohms.

I will check my spare one just to make sure that its ok, but at least no one is say to bleed the brake which was a pain last time I did it.

Thank you for the help.
