Meaning, it thinks your test light is the sensor because the return voltage on the groundside of the sensor has drastically changed. In fact, in most of these ABS systems, if you do “short” the lead, the processor shuts that sensor off (0.0v) until the next key cycle. This way, it avoids any harm coming to the internal circuits of the
The ABS Modulator is a part of the ABS system that controls hydraulic fluid flow to each brake caliper. It does this by opening and closing valves inside the brake caliper, which forces hydraulic fluid into and out of the caliper depending on whether your car’s main body control module has told it to apply or release pressure for any given wheel.
In this video I show you how to pull/retrieve abs codes, how to diagnose and fix the problem. 93-97 Ford rangers, Mazda b2300, b2500, b3000, b4000, Ford expl This allows fluid from the brake system to flow into the hidden areas of the modulator and to the modulator bleeder screws. Open the left modulator bleed screw and depress the brake pedal no more than 3/4″. Close the bleeder screw and release the brake pedal. Wait 15 seconds and repeat the process until no air is seen. NOTE: Use 88 Digital Multimeter with the minimum resistance hold feature enabled for this test.Monitor the resistance between an anti-lock brake sensor terminal and ground on the highest resistance scale of the meter, while wiggling the electrical connector. If the meter shows anything but open circuit, replace the rear anti-lock brake sensor.
Yes, an ABS sensor can be cleaned and reused. Through a thorough cleaning process, such as using a solvent and a wire brush, the sensor can be brought back to its original condition. This process should be done carefully, however, as the wires and other components of the sensor can be easily damaged.
With the key on "RUN", disconnect the connector with the black and orange wire. Take a piece of wire and ground that wire to the metal of the cab or a common ground. The ABS light will flash displaying the code (s). Count the flashes displayed, so say you have 2 sort flashes and 1 long one, thats Code 3. Reply Like. rpf5QG7.
