1996 AUDI A4 sensor

01-271

Note:
The transverse acceleration sensor is very
impact-sensitive, as is the combined sensor for
yaw rate and transverse acceleration. If one of
these sensors is dropped, do not reinstall it in
vehicle under ANY circumstances. Instead, use a
new sensor.

Fig. 1 Sensor for transverse acceleration -G200-
In order to test the sensor, or the combined sensor for yaw rate and
transverse acceleration, the sensor must be removed. Remove rear
seat bench. Unscrew control module for ultra-sound sensors -J347-
and then the sensor. Leave the sensor connected and turn it 90
relative to installation position along its longitudinal axis.

After this, a value of either - 9,8 1 m/s2 or
+ 9,8 1 m/s2 will be indicated on the scan
tool display in display group 5 (use the "Read
measuring value block" function).
A plus in front of the number indicates the
affect on the sensor while driving around a
left-hand curve.

A minus in front of the number indicates the
affect on the sensor while driving around a
right-hand curve.

After reinstalling the sensor for transverse
acceleration -G200- or the combined sensor
for yaw rate and transverse acceleration,
tighten the mounting bolts to 5 Nm. Tighten
the mounting bolts for the control module for
ultra-sound sensors -J347- to 2 Nm.

Note:
Due to an error in the test card 8.0 for the
VAG1551 scan tool and the test card 5.0 for the
VAG1552 scan tool, the display for Measuring
Value Block 5, display group 4 is offset by one
decimal point. This means, for example, that a
transverse acceleration value of 9.81m/s2 is
displayed simply as 0.98 m/s2 .

Output Diagnostic Test Mode (DTM)
(function 03)

Output Diagnostic Test Mode (DTM) is used to
check the function of actuators. Actuators are
also called actors. These are components that
the control module activates when it reacts to the
signals sent by sensors, e.g. solenoid valves,
relays and pump motors.

Note:

Output Diagnostic Test Mode (DTM) only
functions on vehicles containing control
modules with no. 8D0 407 389 A/D/E.
For control modules with no. 4B0 907 389,
output Diagnostic Test Mode (DTM) is not
possible.

Output Diagnostic Test Mode (DTM) can and
must only be selected once after the ignition
is switched on.
