After chassis rebuild in my Escos ABS topped working. I do't miss it much but I wanted to have it repaired and cut off switch installed. And now there is a problem. We've checked all the sensors ressistance - it's OK about 1100ohm, we've chaked the battery voltages and generally done all the diagnostic procedures which can be found on auto data. Everything seams to be working. Maybe ECU is dead? HOw to check it. And how to check the ABS actuators themselves? Any ideas? Also if I managed to cure it. On which pin in the ECU plug do I install cut off switch, or maybe somewhere else??

 

I know about the switch bit!!!!! All you have to do for the switch is locate the plug on the brake fluid reservoir and fit the switch inline to one of the wires. easy!! when the abs is switched off the light is illuminated on the dash.

 

As far as the ABS system goes, Does the ABS light turn on then off when you start then only back on again once you hit 20-30mph?

Could possibly be a sensor with crap on the hall-effect end of the sensor, or even possibly the teeth on the driveshaft could be fubarred.

 

Nope. It lights up and stays on.
