lunchindabox Posted September 21, 2007 Share Posted September 21, 2007 Hello, I just picked up a 92 4x4 ext cab hardbody pickup (pics in the general forum- "added to my fleet") It is a v6 that has 167k miles and runs "okay" When I bought it it had no pressure in the brakes and the "anti-lock" light was on. Fluid was low. I added fluid and only had pressure when the truck was off. Once I cranked it up, I lost presure in the pedal. I decided it was not the master cylinder and checked the rear cylinders. It turned out they were leaking. Changed them both and brakes work well. BUT, I have the "anti-lock" light on. I searched and found little on the subject. But nothing worth talking about. Anyone want to tell me if there is a procedure to diagnose or get codes or anything. Where are the wheel sensors? I saw the procedure to get codes from the ecu, but that didn't have any abs codes. Fluid was topped off when the rear cylinders were done and bled. Thanks in advance. Link to comment Share on other sites More sharing options...

I'm still newbie to the Pathfinder game, so hopefully someone else can shed a little more light on this. Link to comment Share on other sites More sharing options...

88pathoffroad Posted September 23, 2007 Share Posted September 23, 2007 The light will come on if your wiring to the ABS sensor is toast also. The ABS sensor is on the top front of the rear diff. Link to comment Share on other sites More sharing options...
