The electronic control unit of the electronically controlled anti-lock system has a low failure rate. Therefore, most of the malfunctions of the electronic control device are not problems of electronic components, but are caused by poor connection of the wires or contamination of the components. If the fault code indicates that the sensor is faulty, first check whether the contact points of the sensor are in good contact, whether there is rust or the like.
For the anti-lock braking system with accumulator, when the hydraulic system is repaired, the accumulator should first be relieved to prevent the high-pressure brake fluid from being sprayed.
Since the normal operation of the anti-lock braking system must be based on the integrity of the original braking system, the maintenance of the original braking system should be carried out normally. When replacing the brake pad, unscrew the bleeder screw of the brake caliper before pressing the piston, otherwise the dirt in the cylinder may be pressed into the pipe to cause component failure. The returning oil can also cause the electronic control unit to get the wrong information, and the brake anti-lock system can be protected and closed. If the hydraulic brake system needs to be vented during maintenance or use, follow the procedures specified in the vehicle’s instructions for use. Because the deflation procedure with the brake anti-lock system and the normal brake system may be somewhat different, the deflation procedure of the original brake system cannot be blindly copied.
