Definitions
These explanations refer only to this assembly
group: ABS On Board Diagnostic (OBD). These
definitions are not necessarily generally valid.

ABS
Anti-locking brake system. Further information
on the ABS can be found in the relevant self-
study programs.

Display group number Read measured
value block

ASR
Traction Control System

Data bus
Transportation of data. To do this the electrical
signals are brought into a certain format (BUS).
Further information can be found in Self-study
programs. Also called CAN Bus.

Data bus low (high)
The voltage used to transport the data is low
(high). Further information can be found in Self-
study programs.

Speed sensor
Sends speed signals to control module.

Short to positive
Current flows incorrectly to a live component
without supplying a consumer.

Brake pressure release solenoid -F84-
The trip switch is installed in the brake booster
and is required by the control module to
recognize the braking desired by the driver.

Magnetic coil for brake pressure, in brake
booster, -N247-
The brake pressure solenoid is installed in the
brake booster and ensures that a pre-pressure
of 10 bar is available for the ABS/ESP pump.

Read measured value block
The control module can transfer a considerable
amount of test data. This test data delivers
information on the operational condition of the
system and/or sensors connected to it. In many
cases the transferred test data supports
troubleshooting and malfunction repair. The
test data has been summarized into single
display groups because all the information
cannot be evaluated at the same time. The
information can be selected via display group
numbers.

EBC
