It's been a problem that has been progressively getting worse. A year ago, my ABS would randomly go off while braking. Last week, the ABS would kick in randomly more and more often. I checked my fluids and it's topped off at MAX. I checked each sensor to see if there was gunk on it or something. Turns out out the front two sensors were covered with gunk. Cleaned it up and put it back in. Now ABS kicks in under 10mph consistently. So I'm asking, whats the problem? I'm pretty sure I put the sensors back in correctly.

check the codes.
94-95 ignition in the ON position, bridge E1 & TC in the diagnostics box, just like checking codes, read the code from the ABS light Code 11 Open in solenoid relay circuit. Check actuator wiring harness, solenoid relay, solenoid relay wiring harness and solenoid relay connector. Code 12 Short in solenoid relay circuit. Check actuator wiring harness, solenoid relay, solenoid relay wiring harness and solenoid relay connector. Code 13 Open in pump motor relay circuit. Check actuator wiring harness, pump motor relay, pump motor relay wiring harness and pump motor relay connector. Code 14 Short in pump motor relay circuit. Check actuator wiring harness, pump motor relay, pump motor relay wiring harness and pump motor relay connector. Code 21 Open or short circuit in solenoid for right front wheel. Check actuator solenoid, wiring harness and connector. Code 22 Open or short circuit in solenoid for left front wheel. Check actuator solenoid, wiring harness and connector. Code 23 Open or short circuit in solenoid for right rear wheel. Check actuator solenoid, wiring harness and connector. Code 24 Open or short circuit in solenoid for left rear wheel. Check actuator solenoid, wiring harness and connector. Code 31 Malfunction of right front wheel speed sensor signal. Check speed sensor, sensor rotor, wiring harness and connector. Code 32 Malfunction of left front wheel speed sensor signal. Check speed sensor, sensor rotor, wiring harness and connector. Code 33 Malfunction of right rear wheel speed sensor signal. Check speed sensor, sensor rotor, wiring harness and connector. Code 34 Malfunction of left rear wheel speed sensor signal. Check speed sensor, sensor rotor, wiring harness, and connector. Code 35 Open in left front or right rear wheel speed sensor circuit. Check speed sensor, sensor rotor, wiring harness and connector. Code 36 Open in right front or left rear wheel speed sensor circuit. Check speed sensor, sensor rotor, wiring harness and connector. Code 37 Rear speed sensor rotor malfunction. Check rear sensor rotors. Code 41 Battery voltage is less than 9.5 volts or more than 16.2 volts. Check battery and voltage regulator. Code 51 Actuator pump motor is locked or pump motor circuit open. Check pump motor, pump motor relay, vehicle battery, actuator wiring harness, connectors, actuator pump motor circuit and actuator ground bolt. ABS Light Always On Malfunction of ABS ECU. Inspect ABS ECU connector for proper installation and undamaged terminals. Repair as necessary. If connector is okay, temporarily substitute known good ABS ECU. Retest system. -------------------- |
