Reason for change
Reason for block
Complaint:
After replacement of the yaw rate sensor for lateral and longitudinal acceleration (B24/15) the vehicle fails the road test according to the initial
start-up specifications.
Note:
After the road test:
- the yellow ABS warning lamp lights up
- the multifunction display shows the two display messages
-- "Unavailable! - ESP - Diagnosis/Rig Test ! " and
-- "Unavailable! - ABS - Diagnosis/Rig Test ! ",
and the codes 5603 and 5410 are present in the ABR control unit (ABR ECU).
Cause:
The YAW rate sensor (B24/15) delivers incorrect values to the ABR control unit (N30/4) due to being installed under stress, perhaps as a result of a
deformed floor panel at the sensor attachment point.

Remedy:
Reinstall sensor B24/15 correctly.
