This driving test is used to check sensor signals from steering angle, lateral acceleration, brake pressure, and yaw rate sensor. The driving test shall be performed if any components in the "ESP" (anti-spin system) have been replaced or removed.
The "ESP"-driving test can not be interrupted once it has been started.
If the "ESP"-driving test has been activated but not performed correctly, fault codes are stored in the control unit.
The ignition must not be turned off during the driving test.
No "ABS/ESP"-control may take place during the driving test.
Test condition:
Engine on.
Parking brake released.
No faults in the system.
Availability of level surface.
Access to a stretch of road that fulfils the conditions set out below.

Press the "ESP"-button, the warning light for "ESP" will flash for a short time and is then on constantly.
Within 10 seconds, drive through a curve at a speed over 10 km/h and with a steering angle greater than 90 degrees.
The warning light for "ESP" flashes at correct cornering.
Stop the car on a level surface and set the steering straight ahead.
