Symptom:
    A Honda Fit, two days ago due to the noise when driving, in the friend repair shop to check and replace the left front wheel bearings, test found that the problem of noise is solved, but the ABS lights, repair shop analysis that is in the replacement of bearings When the left front wheel ABS sensor ruined, after the replacement failure can not be ruled out.
    Troubleshooting:
    After receiving the car, the maintenance personnel with Honda special detector HDS ABS system fault code and data flow detection, fault code: 22 - left front magnetic encoder failure.
    The front wheel idler to move the engine into the "D" file so that the front wheel idling observation data flow, the right front wheel speed changes with the wheel speed changes, left front wheel no signal output, which can be seen due to the left front wheel problem ABS light is on. Ask the customer that just changed the left front wheel bearings, dismantling found that the bearing is caused by anti-wheel speed sensor can not get magnetic pulse signal.
    Since 2003, Guangzhou Honda Motor Company produced several models using a new ABS sensor structure, and the traditional ABS pulse sensor is completely different. Fit the ABS sensor with integrated IC chip inside, the magnetic encoder is made of magnetic material similar to the magnetic bearing dust cover, installed in the bearing also play a role in dust.
    In the maintenance of ABS system to read the fault code must understand the meaning of the fault code is a sensor or magnetic encoder. Replace the bearing must pay attention to not be able to reverse the bearing (brown face facing the ABS sensor); also can not get the magnetic deformation.
