ESP System Function Test (Conti/Teves)

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 -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.

Special Notes

• 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.
• If you are having trouble getting the function test carried out please contact us directly.
