This driving test is used to check the sensor signals from: steering angle, lateral acceleration, brake pressure and the yaw rate sensor. The test must be done if any of the components of the ESP (Electronic Stability Program) system has been removed or replaced.
Note:
Once activated, the ESP driving test can not be aborted.
Do not press the brake pedal during the ESP driving test on vehicles from year model 2006 (use the parking brake to get the vehicle stopped). If the ESP driving test has been activated but not performed correctly, the fault code 1487 is stored in the fault memory. During the ESP drive test, the ignition must not be switched off.
Test prerequisite:
The engine should be running.
Performance:
Choose the function: ESP driving test. The function is now activated (ABS-control lamp turns on).
Depress the brake pedal heavily until the ESP control lamp starts flashing (the driving test is now activated and the fault code 1486 is stored).
Performe the test drive with a speed of 15 to 30 km/h. Drive through a bend and steer at least 90° with the steering wheel. This procedure shall be performed within 50 seconds after the driving test has been activated. Note: There must be no ABS/ESP regulation during the test drive.
If the ABS and ESP control lamps turn off, the ESP driving test has been performed correctly.
If the ESP control lamp turns off, but the ABS control lamp still is turned on, the ESP driving test has not been done. Reactivate the test by depressing the brake pedal heavily until the ESP control lamp starts flashing. Continue from step 3.
