ESP System Function Test (Conti/Teves)
From Ross-Tech Wiki
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 Warning Light (K47) ON and ASR Indicator Light (K155) OFF.
- Engine RUNNING.
- Vehicle standing.
Instructions
- Press brake pedal firmly until the ASR Indicator Light (K155) goes ON. 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 Warning Light (K47) should now went 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. If Basic Settings Group 103 is not available, repeat using Basic Settings, Group 093.
