EBD

Electronic brake pressure distribution

EDL

Electronic differential lock

On Board Diagnostic (OBD)

The capability of the control module:

Recognize Diagnostic Trouble Codes

(DTCs)

React to DTCs

Store DTCs

and make them available in the Measured

value block. Further information on this can
be found in Self-study programs and test
unit instruction manual.

Performing On Board Diagnostic (OBD)

Connecting the Scan Tool to be able to

check the DTC memory. Further information
on this can be found in Self-study programs
and test unit instruction manual.

Performing electrical check

A targeted check of the electronic

components by performing certain
measurements.

ESP

Electronic Stabilization program

ESP-Sensor unit -G419-, vehicles from

02.02

The sensor for transverse acceleration -

G200-, the sender for rotation rate -G202-
and the sensor for longitudinal acceleration
sensor -G251- (4MOTION vehicles) are
assembled together in a housing.

No communication

There is no connection for exchanging

information between the control modules.

Sender for rotation rate -G202-

Recognizes the rotational movement of the

vehicle along its vertical axis in relation to
vehicle speed.

Longitudinal acceleration sensor -G251-

Determines the correct speed for 4MOTION

vehicles

Steering angle sensor -G85-

Determines the angle and direction of

steering lock (driver's wish). Data is
transferred to control module via data bus
wiring.

Short to Ground

Current flows incorrectly to Ground without

supplying a consumer.

Definitions

01-329

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

Engine braking control

Definitions

01-330

Sensor for transverse acceleration -

G200-

The lateral acceleration sensor is used to

register the speed through curves/bends on
the road and decides which side of the
vehicle the ESP is to brake.

Sender 1 for brake booster/Sensor -2- for

brake pressure -G201-/-G214-

Recognizes the pressure exerted by the

driver and is required to control the pressure
of the pre-pressure system.

Program card version

Always use the most up-to-date program

card. Further information can be found in the
test unit operating instructions.

Sporadic

Happens occasionally

Infinity

The resistance is infinite, open circuit.

= Ohm
