ESP driving and system test

The ESP driving test is used to test the
plausibility of the signals from the sensor for
transverse acceleration, yaw sensor, and
pressure sensor.

Road test vehicle
Some DTCs are only recognized by the On
Board Diagnostic (OBD)while the vehicle is
moving. You can check the entire system during
a road test. During road test, drive at a speed of
at least 60 km/h for 30 seconds. Check traffic
conditions and perform an ABS regulated braking
when appropriate. You will feel a pulsing in the
brake pedal indicating the system is active.

Note:
Once the ESP driving test has been initiated, it
cannot be aborted and must be performed
completely. After exiting the diagnostic, the
ABS/EDL and ASR/ESP lamps remain switched
on in order to indicate that the test is active and
that system function is not available yet.
Warning, ABS and ESP not functioning!

WARNING!

While system is in diagnostic, the
ABS/ESP/EBD is not active. Driving the
vehicle after On Board Diagnostic (OBD) has
detected a malfunction presents the risk of
accident. The brake system will only be
partially functional. Because brake pressure
at the rear wheels is no longer regulated vie
Electronic Brake Distribution (EBD), the rear
wheels tend to brake excessively. This
causes the rear of the vehicle to break loose.

When the use of test equipment is required
during road tests, test equipment must
always be secured to the rear seat and
operated from there by a second person. If
test and measuring equipment is operated
from the passenger seat, the person seated
there could be injured in the event of an
accident involving deployment of the
passenger-side airbag.
