ESP System Function Test
Notes
- The ESP road test serves to check the plausibility of the signals from the lateral acceleration sender, rotation rate sender and pressure sender.
- It should always be carried out after removing or replacing any parts of the ESP system.
- It is not possible to cancel the ESP road test after it has been started. The complete test procedure must be performed.
Pre-Conditions
- ABS/EDS Warning Light (K47) ON and ASR/ESP Indicator Light (K86) ON.
- Engine RUNNING.
- Vehicle standing.
Instructions
- Press brake pedal firmly until the ASR/ESP Indicator Light (K86) goes OFF. A brake pressure of at least 35 bar needs to be reached for this.
- Start road test (Do this on an enclosed site or make sure to drive according to traffic regulations).
- Make a right turn, then a left turn (or vice versa). A rotation rate (turn rate) of ~10 °/s must be reached while driving these turns.
- The ABS/EDS Warning Light (K47) should now have turned OFF.
- A common example for turns like this is driving turns with a radius of 10 to 12 meters (30 to 40 feet) with a speed of 15 to 30 kph (9 to 18 mph).
- The ABS, EDS, ASR and ESP functions may NOT get activated during these test.
- Doing other maneuvers between the turns will have no influence on the ESP System Function Test.
Special Notes
- When this cannot be completed on its own fault code 01486 may be stored. It may be necessary to enter Basic Settings, Group 103, Go.
