| Perform ESP road and system test (vehicles with ABS/TCS/ESP BOSCH 8.0) |
| The ESP road test is a plausibility test of the signals from the lateral acceleration sender -G200-, yaw rate sender -G202- (both senders in the ESP sensor unit -G419-) and the brake pressure sender 1 -G201- (in the hydraulic control unit). |
| The ESP road test should be performed after each replacement of the electrical components of the ESP system. |
| If the ESP road test is initiated, it can no longer be interrupted and must be performed. |
| Perform basic setting of vehicle diagnosis, measurement and information system -VAS- → Chapter. |
| –
| Disconnect vehicle diagnosis, measurement and information system -VAS-. |
| –
| Depress the brake pedal forcefully until the ESP and TCS warning light -K155- goes out, at the same time the ABS warning light -K47- lights up. |
| –
| Now carry out the ESP road test. |
WARNING | The rules of the road traffic regulations must always be given priority. |
|
| –
| Drive a right or a left curve. Subsequently carry out a change of direction and drive a left or a right curve. |
| –
| After cornering, drive straight ahead for a certain period of time. |
Note | t
| A curve with a radius of 10 to 12 meters and a speed of 15 to 20 km/h must be driven in approx 4 seconds during cornering. |
| t
| It must be driven in such a way, that no ABS, EDL, TCS or ESP control is activated. |
| t
| If there are other traffic dependent driving manoeuvres between cornerings, they will have no influence on the ESP road test. |
| If the ABS warning light -K47- goes out, the ESP road and system test was successfully performed and ended, the system is OK. |
| If the ABS warning light -K47- does not go out, the ESP road and system test was not successfully performed. |
| If the ABS warning light -K47 - and the ESP and TCS warning light -K155 - light up, there are faults in the system. |
| –
| Interrogating fault memory. |
