ESP System Function Test (Conti/Teves)
From Ross-Tech Wiki
ESP System Function Test
- 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.
- ABS Warning Light (K47) ON and ASR Indicator Light (K155) OFF.
- Engine RUNNING.
- Vehicle standing.
- Press brake pedal firmly until the ASR Indicator Light (K155) goes On -or- a change in the lamp behavior has occurred. 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 turn 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 should have no influence on the ESP System Function Test.
- If the ASR Indicator Light (K155)light turns off but the ABS light stays on, then the test has timed out. You must come to a complete stop and again press the brake pedal firmly until the ASR Indicator Light (K155)changes.
- Several customers have reported success by driving 10MPH (16KPH)in a straight line for 10 seconds, then turn the steering wheel almost 360 degrees (left or right) and do a complete circle.
