This basic setting is used to check the signals from the lateral acceleration sensor, the yaw rate sensor and the pressure sensors.
The sensors are only fitted to cars with ESP (electronic stability program).
The test must be done if any of the components of the ESP system has been removed or replaced.
Note:
Once activated, a drive test must not be interrupted; it must be completed correctly.
Method:
Choose the basic setting: ESP drive test.
The drive test has now been activated.
Quite the basic setting menu and close communication with the control unit.
Start the engine.
Depress the brake pedal heavily until the ASR/ESP indicator light goes out.
Test drive as follows:
Drive through a left-hand bend after a right-hand bend. When driving through the bends an angular velocity of at least 10°/second must be reached. NOTE: There must be no ABS/EDL/ASR/ESP control during the test drive.
The ABS/EDL indicator light goes out.
If the indicator lights do not go out:
If the ABS/EDL indicator light does not go out, the test has not been performed correctly.
If the ABS/EDL indicator light does not go out, and the ASR/ESP indicator light comes on again, there is something wrong in the system.
