Read measuring value block: display group 5
NOTE:
The On Board Diagnostic (OBD) is terminated by ABS control module (w/EDL) -J104- if road speed exceeds 19 km/h.
If the steering angle sensor is OK, a display will follow even if a zero position adjustment was not performed.
If no display appears, press button -C-, select Function 02 and Check DTC Memory. Repair malfunction according to DTC table . See ESP DIAGNOSTIC TROUBLE CODE (DTC) MEMORY, CHECKING .
NOTE:
The lateral acceleration sender and the combined sender for rotation rate and lateral acceleration are very sensitive to impacts. If one of these sensors is dropped by accident it must not be installed in the vehicle: install a new sensor.
Sensor for transverse acceleration -G200-
- Remove the sender (or the combined sender for rotation rate and lateral acceleration) in order to test it.
- Take out the rear seat bench. Unscrew bolts and detach control module for ultra-sound sensors -J347- and then the sender.
- Leave the connector plugged in, and turn the sender 90° about its longitudinal axis in relation to its normal installed position.
This should give a reading of - 9.8 +/- 1 m/s 2 or + 9.8 +/- 1 m/s 2 on the scan tool in Display Group 5 of the function "Read Measuring Value Block".
A positive (+) reading will be indicated when the sender is subjected to lateral acceleration in a left-hand corner.
A negative (-) reading will be indicated when the sender is subjected to lateral acceleration in a right-hand corner.
- When installing, tighten bolts securing sensor for transverse acceleration -G200- or combined sender for rotation rate and lateral acceleration to 5 Nm (44 in. lb).
- Tighten bolts securing control module for ultra-sound sensors -J347- to 2 Nm (18 in. lb).
NOTE:
Due to an error in test card 8.0 for VAG 1551 scan tool and test card 5.0 for VAG 1552 scan tool, the value displayed in the measured value block (Display group 5, Display zone 4) is reduced by a factor of ten. In other words a lateral acceleration of 9.81 m/s 2, for example, is indicated incorrectly as 0.98 m/s 2.
NOTE:
The display group numbers can be selected in sequence by pressing buttons -1- and -3- ((VAG 1551 scan tool) or buttons uparrow and downarrow ((VAG 1552 scan tool) or by pressing "uparrow "and" downarrow" on the screen of VAS 5051 vehicle diagnostic, testing and information system.
- Press button -C- in order to enter the display group number manually.
Indicated on display
