ABS light on 95' Legacy

[Bushwick]

The light started as intermittent and is now on full-time. ABS seems to still actually be working though as tires won't lock-up under heavy braking.

 

Is there a way to trace if it might just be a wheel sensor? Only thing odd the car does is sometimes after first starting and moving, when 1st applying the brakes, the ABS seems to either be activated or deactivated briefly as I can hear it make a noise similar to when you, say, hit the brakes on snowpack and the tires loose traction and you can hear the ABS click. Pedal effort alters when the first stop occurs then stabilizes. From that point onward, brakes act normal minus the ABS light remaining on.

Probably a wheel speed sensor. If one sensor shows that the wheel has stopped or is turning significantly slower than the rest the ABS will engage when you press the brake pedal. If that wheel speed signal does not change the ABS module determines the sensor to be faulty, so it deactivates the ABS after that until the key is turned off. Once turned back on the ABS will be active again until the fault occurs.

 

Poke under the dash and find the small black 6 pin plug over near the green test mode plugs. There's a couple of black ground wires with bare spare pins taped into the same harness. Pull those down and insert one of the ground spades into pin 6 of the black plug.

Turn the KEY on and the ABS light will blink any stored codes. Code 11 is the start code and will display first, just showing that the module is in read-mode. Stored codes will display after that in the order which they were stored. (Newest to oldest)

The first digit will be slow blinks, the second digit will be fast blinks.

You have to pay close attention because the second digit of the code blinks very quickly.

 

To clear codes after reading: leaving the key On, remove the ground pin, and insert the ground spade into pin 6 three times, (leaving the pin inserted for at least 0.2 seconds, then removed for at least 0.2 seconds) then remove the pin.

Thanks for posting this. Whereabouts is this test connector? Under the driver-side dash? Would it be on left or right side i.e. above gas pedal area or further left? This thing taped to the harness, is it a wire with spade ends? Or some sort of metal contraption?
