it should reset after three goes

if there is no persistent fault. The brakes will work as per old-fashioned non-ABS ones if the light is on. If it doesn't reset after 3 starts, see a mechie or search here on ABS light/sensors.
The light on our SL came on after we had to brake hard enough for the system to work. I couldn't see anything wrong, but booked it in anyway. Sure enough, the third start cleared the warning, but I let my mechie have a look anyway as I'm still getting used to the car.

done lots of stop starts over several days still on soild! how do ya self test?

 

[Myros]

I'll have a shufti in my Haynes.

Could be a while.

cheers, does it show how to test sensors and what rez they should be?
am i correct that there is only 1 on the rear diff?

 

[vts70]

did an ohms test:
o/s/f ABS Sensor 685ohms
n/s/f Abs Sensor 0 ohms me thinks this is the prob!
Rear sensor in from diff (in boot) 0.001 ohm

on Volts when spinning wheel:
o/s/f 1v when spinning
n/s/f 1 to 2v no matter if you spin wheel or not! again i think this is at fault!

what do ya think guys?

 

[Myros]

you might have it by the ears there

98 was the change from one to two rear sensors. sounds like you're early rather than late. I can't believe I paid 17squid for a manual that tells me to go to the dealers if the ABS light stays on. Sorry i can't come up with anything more constructive.

 

[vts70]

thats ok, no prob, thanks for looking ;-)

ABS very sensitive to voltage dropping below 12V, then light will come on, have you checked your battery is in good state of charge?

 

[vts70]

yes all ok alt at 13.7v

This might be worth a look
I had the ABS light intermittantly lighting up on my 98 (S) plate C180, took it to my local independant who plugged it in the diagnostics (£40) and informed me it was the electronic switch under the footbrake that had gone down. he replaced it while I waited for £15 and all was well again in 30minutes.
