ABS Unit 94 Blazer
 

The ABS light just came on in my 94 s-10 Blazer (Tahoe). Tech said several codes had been sent. Claims the Hydraulic unit needs to be replaced, but cannot find the right part. I tried to go to the parts store and they want to sell me a computer module which doesn't seem to exist on my vehicle. Any help on this would be great. Part #'s or experiences?

well my abs light has come on also and has been on. i've talked to people and they've said to first clean off the abs sensors. sometimes some dirt gets in there and causes the sensor to go. (u have to take of the tire then the rotor and it will be a lil block just above the abs timer sort of thing that looks like a gear w/ square teeth)

also check to see if some grease or something has come onto the abs sensor. this could be caused by a bad wheel bearing that is pushing out the grease and pushing it onto the abs sensor. otherwise the sensor could just be bad.

as the tech what codes it reads and then you can look up the codes and see what they say. theres a lot of stuff on here about codes and i'm sure someone can help u out.
