Read the dynamic data stream: When the diagnostic instrument is connected, turn on the ignition switch and rotate the tire while reading the data stream of the ABS sensor. If the data stream of a certain wheel does not change, it means that the ABS sensor is damaged or the wiring harness is damaged.
Resistance measurement: Use a multimeter to measure the resistance value of the ABS sensor, which is generally around 1000Ω. If the difference is large, it means that the ABS sensor is damaged. In addition, this method is mainly applicable to the magnetoelectric ABS sensor.
Voltage measurement: Use a multimeter to measure the voltage value of the two wires of the ABS sensor. The two wires are the power wire and the signal (ground) wire. The voltage of the power line is about 12V, and the voltage of the signal line is about 0.5V. In the case of , the signal voltage will jump regularly. If the measurement results are different from this, it means that the ABS sensor is damaged. In addition, this method is mainly applicable to Hall-type ABS sensors.
Well, the above is part of the knowledge about the ABS sensor, I hope it can be helpful to all riders and reduce the troubles of daily car use and car maintenance!
