Anti-lock Brake System
ABS/EBD introduction
1. Operation
The vehicle's Anti-lock Brake System (ABS) is a type of increasingly popular brake safety device. It detects the
wheel's speed using wheel speed sensor detection. After signal processing, the wheel speed will be transferred
to the computer, which controls the solenoid valve’s operating condition and the pressure inside the brake wheel
cylinder to avoid wheel locking by using certain calculations and control methods based on the wheel speed.
ABS helps the vehicle to avoid sliding, deviation, fishtailing, and losing steering control capacity. ABS improves
the vehicle’s handling capability, stability and shortens braking distance. It also helps the vehicle to avoid the
partial wear and tear of wheels, hence improves the tire's useful life.
Electronic Brake Distribution (EBD) is used to adjust the vehicle's rear wheel brake pressure by using the ABS
components when the ABS does not respond to vehicle braking. It is also used to balance the vehicle’s front and
rear wheel brake pressure, maximizing the vehicle's braking efficiency. EBD uses the ABS components, yet its
controlling logic is independent from the ABS. After the ABS responds, the EBD will disengage.
2. Basic structure
3. ABS working process
(a) Pressure rising phase: While service braking, oil pressure output from the pump passes the inlet solenoid
valve and enters the brake wheel cylinder. The brake generates braking force and the wheel speed sharply
declines until the ABS control unit detects that the wheel is starting to lock via the wheel speed sensor
detection.
(b) Pressure maintaining phase: When the ABS control unit detects that the wheel is starting to lock via wheel
speed sensor signal, the inlet solenoid valve closes, with the outlet solenoid valve shut as usual. The
pressure maintaining phase thus begins.
(c) Pressure drop phrase: During the pressure maintaining phase, the wheels tend to lock further. This brings
the ABS into the pressure drop phrase. With the inlet valve closed and the outlet valve open, the hydraulic
pump starts working, and brake fluid returns to the brake pump from the wheel cylinder by passing through
the low pressure accumulator. The brake pressure reduces and the brake pedal bounces back.
(d) Pressure maintaining phase: With the degree of wheel locking decreases and wheel speed begins to
increase, the pressure maintaining phrase begins.
(e) Next cycle’s pressure rising phase: When the wheels reach a certain speed, the ABS enters the pressure rise
phase and starts the next cycle.
Note: The ABS's pressure adjusting frequency is generally 2 to 4 cycles per second.

Areas of importance in circuit maintenance
1. Before operating any electronic devices, and when tools or maintenance devices may easily make
contact with an uncovered electronic terminal, please make sure to turn the ignition switch to the LOCK
position, and then disconnect the battery's negative cable to avoid injury or vehicle damage. When the
ignition switch is on the ON position, please do not disconnect the battery's connecting wire or take out
the power's fuse, regardless if the engine is running or not.Otherwise it would seriously damage the
ECU and related microelectronic devices such as sensors.
2. When changing the fuse, please make sure that the new fuse possesses the proper current rating,
and is not above or below this rating.
3. When repairing the wire harnesses of the airbag and pretensioner, only specified contact points,
plugs, and wires are allowed to be used.
4. Before repairing the wire harness, make sure to eliminate any factor that might cause damage,
for example, the edge of a vehicle body part is too sharp, or the used electronics are damaged or
corroded.
5. Shielded wire should not be repaired, it must be replaced entirely once it is damaged.
6. Unless it is specified during the test, please do not use an analog multimeter to test the ECU and
sensor, instead use a high-impedance digital multimeter (internal resistance should be ≥10 kΩ) or a
vehicle multimeter for inspection.
7. When inspecting the connector with a digital multimeter, take the waterproof rubber cover off the
connector, and tightly insert the test pen along the connecting terminal. Don't use too much force, as
to avoid cracking the connector.
Circuit inspection steps
The principle of troubleshooting is to confirm the "possible cause". Once the possible cause is confirmed, the
components that need to be inspected are limited to the components that are related to the possible cause. The
confirmed possible cause should be based on theory and be supported by facts, but not just by intuition. If
one tries to solve the problem but does not adopt the proper troubleshooting steps, it may make the problem
worse. Then the possible cause not only can't be confirmed, but also maintenance can't be performed properly.
Troubleshooting should adhere to the four steps below:
1. Observe the symptoms carefully, inspect if there is anything else abnormal, and record it.
2. While confirming the possible causes, study the circuit diagram carefully, and regard it as a whole
system in order to understand the circuit. Thorough knowledge of switches, relays, and other
electronic components is obligatory for proper analysis.
3. Inspect and eliminate the problems one by one until the cause is found.
4. After the malfunction is fixed, make sure to check if the inspected system is working properly, and also
check if the maintenance may have caused any new problems.
