have a 97 r reg escort gti and when i switch on the abs light comes on and then goes out as it meant to, however if its wet or i go through a large puddle the abs light comes on & stays on,if i then switch the engine off for a while & then switch it back on the abs light stays on and doesnt go out, however if i then start to drive the light then goes out and then its back to normal. Its very intermitant any ideas whats wrong?

 

If the abs lamp comes on while driveing its normally a abs wheel sensor at fault.

if it comes on after going through a large puddle it could be the sensor cant do its job
as its to dirty ect. as it drys out and you stop and then start the engine again the abs
ecu does its checks and all is fine.
take it to your local garage who should be able to do a simple check to find out
if the abs ecu has stored a code.
hope this helps

or just clean the sensors and check the gaps from the sensor to the pickup spiggot. Also make sure that your connections are beginning to corrode.

 

thanks for the help guys
