1. The steps for you to maintain ABS system
The use of automobile ABS system maintenance
Automotive anti-lock braking system (ABS) is in the conventional braking device on the basis of
the developed a kind of mechanical Truck Diagnostic Tools and electrical integration of new
brake system, its structure, use, maintenance and so on all has its characteristics. Although the
ABS system model is various, structure and more complicated, but its use in the same
maintenance. Whether used maintenance which ABS system, all should pay attention to the
following problems.
1. pay attention to clean
1). In order to ensure the maintenance of quality, should keep maintenance site and removable
parts clean, prevent dirt dust into the pressure regulator or brake lines.
2). Keep the electronic controller and wiring harness connector car Diagnostic Software clean,
prevent oil, water and dust smudginess connector, or wire connector will rust, leading to poor
contact, the system can't work normally.
3). Keep the wheel speed sensor head and ring gear clean, prevent foreign body especially
ferromagnetic material cleave its surface. Otherwise it will affect the accuracy of the wheel speed
sensor signal, the system doesn't work properly, can't even work.
2. pay attention to protect electronic controller (ECU)
1). In the ignition switch is not closed, not before disassembling system of wire plug or electrical
components, can't power operation.
2). Due to the electronic controller in high temperature environment and electrostatic OBD2 コー
ドリーダー particularly sensitive, in the car painting and welding work, must first break
electronic controller, and a good anti static electrical appliances.
3). Battery should keep enough electricity state, if the battery kui electric (voltage is too low), ABS
system will not work. When using the power of the car battery to charge, must first disconnect
battery is negative joint column on the wire, and then to charge the homework.
3. the replacement parts must be correct
1). The selection of tire
For does not affect the ABS system control effect, should choose the original car tire or in the car
manufacturers recommended tire, to ensure that the outside diameter of the tire, adhesion
performance, moment of inertia and the original tire the same.
2). Brake pipe and the selection of rubber parts
Because ABS system brake line to obd コネクタ販売 bear larger brake pressure, when the
brake line have sag, distortion, rupture or joint damage, it must be replaced by ordinary brake
pipe fittings. Rubber parts for use in accordance with the provisions also should use the standard
high voltage resistance to corrosion, lest line damage caused by the failure of the brake suddenly,
cause an accident.
4. correct dismantling

2. 1). In dismantling electronic controller (ECU), to prevent the collision, otherwise the ECU in the
external vibration condition will be damaged.
2). Dismantling sensor, not disorderly hammer. Wheel speed sensor are not interchangeable,
more don't wrong, loading before coating antirust oil.
3). Adjust sensor air gap, should use a magnetic feeler, such as plastic or Honest OBD2 Diagnostic
Tool copper feeler, can use paper.
4). Maintenance wheel speed sensor, should prevent bruising ring gear teeth and sensor head,
not will ring gear as support move, otherwise, will cause tooth deformation, the wheel speed
signal is not normal, influence the normal ABS system is made.
