ABS problem

4 should be a open sensor circuit on the left side, got abs on rear axle only ? Could be air gap, harness going to it , or sensor. Guessing its the air gap. Since the other side cured its self. But check both sensors.

 

first of all check configuration. how many sensors?

 

Ok, first of all use small screw driver to bend female connector terminals to get better contact. Do it on sensor wire and on extencio cabel on place it is connected to modulator

 

If you have this kind of system, it will tell you more than you ever wanted to know:
