2012> G 2.0 DOHC> Brake System

VERIFICATION OF THE BRAKE BOOSTER
Check operation of the brake booster, you can use the following simple test.
Run the engine for a minute or two and then stop it. If the first pedal is full, and every time you press the pedal stops higher and higher, the amplifier is functioning correctly. If the pedal
height remains unchanged, amplifier fault.

1.
With the engine off, press several times on the brake pedal.
Then press the brake pedal and start the engine. If the pedal is lightly pressed, power is normal. If no changes are made, power failed.

2.
Depress the brake pedal with the engine running and the engine stopped. Hold the pedal down for 30 seconds. If the pedal height does not change, power is good, if the pedal rises, power
failed.
If three checks described above, ended with a positive result, the work of the brake booster can be rated as good.
3. If at least one of the above tests give unsatisfactory results, check the check valve, vacuum hose and an amplifier.

ABS (antiblokirov. brake. System) - Description and Operation

2012> G 2.0 DOHC> Brake System

Description
This part of the documentation related to the hydraulic control unit (HCU) and the electronic control unit (ECU) of the hydraulic electronic control unit (HECU)
These data refer to the wiring diagram and are necessary for mounting the ECU ABS / ESP.
This block provides the following functions.
a. Input signal from the pressure sensor, sensor steering angle, yaw rate sensor and lateral acceleration and wheel speed sensors on each wheel.
b. Control braking / traction / yaw moment.
c. Function of fault tolerance.
d. Self-diagnosis function.
e. Interface for external diagnostic device.
Position: the engine compartment
a. Tube length brake line from the opening of the main brake cylinder to the inlet block HECU not exceed 1 m
b. It should not be close to the engine and to be below the wheel.
Tripping
The electronic control unit (ECU) involved in the work by giving it the working voltage (IGN).
Upon completion of the initialization phase, the ECU is ready.
In operation, the ECU should be ready (within specified limits of voltage and temperature) to process the signals from the various sensors and limit switches according to the control
algorithm, some software and manage the operation of hydraulic and electric drive trains.
Signal processing wheel speed sensors
The ECU receives signals from the wheel speed four active wheel sensors.
These signals are converted into a voltage signal by the signal processing circuit after the current signal from the active wheel sensors, and input to the unit MCU.
Solenoid valve
When one of the conclusions of a solenoid coil valve control relay valve is served a positive voltage, and a second terminal connected to ground through a semiconductor integrated circuit, is
the inclusion of the solenoid valve.
Electrical parameters of the coil are continuously monitored using test pulses under normal operating conditions.
Voltage limits
Overvoltage
In the case of overvoltage (above 17 ± 0,5 V) ECU disables relay valves and shuts down the system.
a. When the voltage drops to within the operating range, the system goes back to normal after the initialization phase.
Reduced voltage
In the case of low voltage (below 10 V) there is a ban on the control and ABS warning lamp.
b. When the voltage returns to the operating limits, warning light turns off and the ECU will come back to normal operation.
Checking the pump motor.
After turning on the ignition and reach a speed of 15 km / h (9 miles / h) motor ECU checks.
Diagnostic Interface
Failures observed by the ECU, this block is encoded and stored in EEPROM (EEPROM). When the ignition they read diagnostic equipment.
Diagnostic interface can also be used to check the ECU during the manufacturing process and to activate the unit when passing HCU series of tests in production (check for venting or check
the brakes and roll bars).
Warning Lamp Module

ABS warning lamp module

Active Unit ABS warning light indicates a self-diagnosis and the presence of failures ABS.
ABS warning lamp is lit in the following cases:
a. During the initialization phase after ignition (continuously for 3 seconds.)
b. In the case of the ban on the issuance of ABS operation as a result of failure.
c. In the diagnostic mode.
d. When you disconnect the connector from the ECU unit.
1. e. In the dash light is on when the module CAN can not be established.
Control lamp module PARKING / EBD
Active Unit EBD warning lamp indicates self-diagnosis and the presence of system failures EBD.
However, in the case of the limit switch circuit brake warning light, this always comes on, regardless of the system EBD.
EBD warning lamp is lit in the following cases:
a. During the initialization phase after ignition (continuously for 3 seconds.)
b. With the closure of the limit switch or the brake at a reduced level of brake fluid.
c. If the operation of the system EBD differs from the norm.
d. In the diagnostic mode.
e. When you disconnect the connector from the ECU unit.
2. f. In the dash light is on when the module CAN can not be established.
MANAGEMENT Antilock Braking System (ABS)
Inhibition in normal mode without ABS
In normal braking, the solenoid valve is energized, the inlet valve is open, the exhaust valve is closed. In normal braking, the solenoid valve is energized, the inlet valve is open, the exhaust
valve is closed. Brake pedal for the brake fluid is fed into the wheel brake cylinders via a solenoid valve. When you release the pedal fluid returns to the master cylinder through the intake
valves and control.
The pump
Solenoid Valve State Valve Passage motor
Inlet valve (normally open) OFF OPEN Master Cylinder Cylinder ⇔
Drain valve (normally closed) OFF CLOSED ⇔ slave cylinder reservoir OFF

1.
2. The Clear
If emergency braking begins wheel lock, block HECU first reduces brake fluid flow through the solenoid valve and energizes a solenoid. At this point, the inlet valve is closed and the brake
fluid is cut off from the GTZ. The exhaust valve is opened, and the brake fluid flows into the tank through the CTC, as a result of which the pressure decreases.
The pump
Electromagnet State Valve Passage motor
Inlet valve (normally open) ON CLOSED Master Cylinder Cylinder ⇔
Drain valve (normally closed) ON OPEN ⇔ slave cylinder reservoir ON
3. Retention mode
After reaching the minimum pressure in the TCC unit HECU gives the command to maintain pressure on the solenoid valve, and the intake valve is energized and no exhaust. At this point,
the intake and exhaust valves are closed and the brake fluid is held in the TCC.
The pump
Electromagnet State Valve Passage motor
Inlet valve (normally open) ON CLOSED Master Cylinder Cylinder ⇔
Drain valve (normally closed) OFF CLOSED ⇔ slave cylinder reservoir OFF
4. ZOOM MODE
If the block HECU detects that the wheel is not locked, the voltage supply to the solenoid valve stops. Power is not available for each solenoid valve, brake fluid flows through the inlet
valve to the CTC, the pressure increases.
The pump
Electromagnet State Valve Passage motor
Inlet valve (normally open) OFF OPEN Master Cylinder Cylinder ⇔

The electronic brake force distribution (EBD) - Description and Operation

2012> G 2.0 DOHC> Brake System

PRINCIPLE OF ELECTRONIC brake force distribution (EBD)
System EBD (electronic brake distribution system effort) as a subsystem of the ABS control maximum braking the rear wheels.
The EBD system makes better use of the elements of the highly developed system of ABS by driving the rear wheels slip in the range of partial inhibition.
Braking force controlled by an electronic system, is close to optimal. This eliminates the need for a proportional valve.
Since the pressure limiter is a mechanical device, it has limitations in achieving the ideal brake force distribution to the rear wheels, as well as in the implementation of the flexible brake
force distribution in proportion to the load and the weight of the car. Failure driver can not see it works or not.
System EBD, run by the control unit ABS, calculates the slip ratio of each wheel at the current time and adjust the pressure in the brake system rear wheel so that it does not exceed the
amount of brake pressure set for the front wheels.
In the case of system failure warning lights EBD warning lamp EBD (brake light).
BENEFITS
a. Enhancing the functionality of the base brake system.
b. Make up the difference of the coefficients of friction.
c. No need for a proportional valve.
d. A warning signal of a fault in the test light.

ESP (electric system. Stabilization) - Description and Operation

2012> G 2.0 DOHC> Brake System

description of the ESP
Optimal safety while driving is now associated with electronic stability program (ESP).
ESP recognizes critical driving conditions, such as panic driver in dangerous situations, and stabilizes the vehicle by braking individual wheels and intervention in the engine management.
ESP system adds to the functions of systems ABS, TCS, EBD and ESP another function - active yaw control (AYC). While the functions of the ABS / TCS control wheel spin under braking
and acceleration, and therefore mainly affects the longitudinal dynamics of the vehicle, the function of the active yaw control stabilizes the vehicle about its vertical axis.
This is achieved by interruption to brake individual wheels and adjusting the instantaneous torque without taking any action by the driver.
Essentially ESP stabilization system consists of three components: sensors, electronic control units and actuators.
Stability control feature works in all driving conditions and work. In certain driving conditions, the function ABS / TCS team driver can be activated simultaneously with ESP.
The failure of the stability program continues to run the basic security system - ABS.

DESCRIPTION OF ESP
The ESP system includes the functional blocks ABS / EBD, TCS and AYC.
Function ABS / EBD: ECU converts the signals from the four wheel speed sensors (active type) to a rectangular shape. For these input signals ECU calculates the vehicle speed and
acceleration or deceleration of the wheels. Then, the computer determines the need to operate the ABS / EBD.
Functional unit TCS prevents the driving wheels from spinning by creating an additional brake pressure and reduce engine torque using the CAN data exchange. This unit, as well as ABS,
uses the signal wheel speed sensor to determine wheel slip.
AYC function prevents steering movements that could affect its stability. The assessment exercises function AYC uses sensor signals to maneuver (yaw sensor, a lateral acceleration sensor,
the sensor steering angle).
If the maneuver can lead to loss of stability (over-or under-turning), AYC function inhibits certain wheel and transmits a signal via the CAN bus to reduce engine torque.
After ignition, the ECU is constantly diagnosing system failures (self-test). When a fault is detected, the ECU informs the driver by means of warning lights Brake / ABS / ESP (warning to
the sustainability of the presence of failures).
