Restart number 1:Activate the brake pedal

Conditions:

1. Vehicle speed is zero;
2. The air pressure in the brake system is greater than 10 bar;
3. If the fault is with a trailer brake control modulator, release the parking brake.

Actions:

1. Switch off the ignition, wait at least 15 seconds, the data will be reset from the control unit of the brake system.Do not depress the brake pedal during this time;
2. Ignition ON;
3. Wait at least 15 seconds.At this time the car should not move, do not press the brake pedal.The red triangle on the dashboard is lit.Functions EBS, ABS limited;
4. Press fully on the brake pedal;
5. Hold the brake pedal for at least 5 seconds;
6. Release the brake pedal;
7. Do not press the brake pedalfor5 seconds.

In case of a successful restart, the red triangle on the dashboard will go out, the fault codes will become inactive.Functions EBS, ABS is not limited.

In the event of a failed restart, the triangle will not go out, the brake system remains faulty.

The reasons:

1. The restart is not true:
   • brake pedal depression time exceeded 25 seconds;
   • the car was moving.
2. The restartis correct, but there are malfunctions in the brake system, such as a broken wire or a modulator, etc.In this case, the operation of the car is not recommended, you need to find the cause and eliminate the fault;
3. Try restarting a few more times.

Restart number 2:The speed of rotation of the wheels

Conditions:

1. The brake pedal is fully released;
2. Vehicle speed is zero;
3. Additional axes are omitted.

Actions:

1. Switch off the ignition, wait 10 seconds.Turn on the ignition, wait 5 seconds;
2. Slowly accelerate the car until the speed exceeds 15 km / h.Acceleration time must be at least 15 seconds, while theanti–skidsystem TCSshould not be activated.In case of presence of active SID codes 1, 2, 3, 4, 5, 6, 7 PSID 70, 71, 72, 73 FMI2, it is required to accelerate to at least 40 km / h.
3. At least 2 seconds to maintain a speed of at least 15 km / h.In case of a successful restart, the lamp on the instrument panel will go out, the fault codes will become inactive.In case of unsuccessful restarting, the lamp will not go out, fault codes are active, there is a fault in the braking system.

Restart number 3: The speed of rotation of the wheels

Conditions:

1. The brake pedal is fully released;
2. Vehicle speed is zero;
3. Additional axes are omitted.

Actions:

1. Switch on ignition, wait 10 seconds.Turn on the ignition, wait 5 seconds;
2. Accelerate the car to a speed of 25 km / h to 90 km / h;
3. Maintain a constant speed of at least 15 seconds.Acceleration not more than 0.5 km / h.

In case of a successful restart, the fault codes will become inactive.

In the event of a failed restart, the fault codes remain active there is a fault in the braking system.

Restart number 4:Maneuverability

Conditions:

1. The brake pedal is fully released;

Actions:

1. Switch off the ignition, wait 10 seconds.Turn on theignition, wait5 seconds;
2. Accelerate the car to a speed of at least 20 km / h;
3. To drive a car in a straight line, avoid wheel slip, and sharp movements of the steering wheel;
4. Driving a car on the road with turns, avoid slipping wheels, and sharp movements of the steering wheel.

Results:

1. The sensors are checked while the vehicle is moving in a straight line and with turns.
2. The result is indicated by the VDC1 message (used by several control units).Through this message the control unit.
3. EBS informs you that ESP is fully operational after a proper restart.

Restart number 5:Reinstall the control unit

Actions:

1. Turn off the ignition;
2. Wait 10 seconds;
3. Ignition ON, Do not press the brake pedal.
