ABS Light on, and ABS not working (1 Viewer)

[REZARF]

I have a 99 100 series with 375k on the clock. I have a constant on ABS light and my ABS isn't working. I am slipping around in the snow verses feeling the pulsing I normally feel when the computer takes over on snowy roads.

I assume there are sensors and computers involved. Any ideas where to poke around first? I am NOT getting any error codes on my ScanGauge 2.

could be many things. Techstream would probably help with the diagnosis.

I would check all the ABS sensor wires, pull them out of the hubs and clean the ends to make sure they are getting good signal. test for continutiy to each wheel sensor. Always start with the easist things first. But if you havent replaced your brake booster yet, you may want to budget for that

ABS error codes don't go through the OBD system, there's another way to read the code, jumping a terminal and counting the number of times the ABS light flashes.

Here are the ABS pages from my '99 LC EWD book. It's a pretty simple system on the early years.
