OPERATION
Braking
Brake pedal test:
You shall press the pedal as follows: After the detection of the fault, the ignition shall be switched off and on again to reset the EBS. • To turn off the EBS, the ignition shall be off at least for 5 seconds and • When the ignition is off, the brake pedal shall be released to avoid braking without resetting the EBS in waking mode. • After the ignition is switched on, for at least 7 seconds: • The vehicle shall remain stationary and the brake pedal shall be released. • The EBS supply voltage shall be sufficient for electronically controlled braking. • In case of TCMmalfunctions, the parking brake shall be released. • The warning light is on, system restriction is active. • Pressing the brake pedal under following conditions: • When the vehicle is stationary, a brake pedal request warning message appears on the display. • Do not start to press the pedal within 7 seconds after the ignition is turned on. • The pedal stroke shall be increased to the full brake position without any
conditions. • The full braking position shall be maintained for at least 3 seconds. • The pedal shall be released to the full release position without any conditions. • The brake pedal shall remain in the fully released position for at least 3 seconds. • The warning light illuminates. System restriction during braking is not active. Braking is controlled by the electronic pressure control. Brake pedal test successful: • No fault is detected during braking. • Warning lamp is off, system restriction is not active. Brake pedal test failed: • When a fault is detected during braking or • When the maximum braking period of 25 seconds has expired or • If the car starts to move. • The warning light remains on, system restriction is active. • To restart the brake pedal test, the ignition shall be switched off and on again.
There are some faults that cannot be directly detected by EBS and that can be detected by monitoring the behaviour of the vehicle and the brake system only. These monitoring functions are called plausibility checks. If a plausibility error is detected by EBS, the systemmay be restored when the EBS performs a system test (called reverse test) according to legal requirements and the test result is positive (operation of the brake system is correct) only. This means that a reverse test is required when the cause of the fault corrected (in case of a temporary fault or when the vehicle is repaired). In order for the EBS to perform the reverse test, the driver shall press the brake pedal once under a certain condition. When the EBS requires that the pedal shall be pressed in this way to resolve the fault, it shall send a request with the following fault code: Path: 253 (Vehicle braking system) Type: 201 (Request for pressing the brake pedal) (SPN 64969)
