ESP System Function Test

General

  • The ESP System Function or Road Test serves to check the Plausibility of the Signals from the Lateral Acceleration Sensor (G200), Rotation/Yaw Rate Sensor (G202) and Brake Pressure Sensor (G201).
  • The ESP System Function Test should be performed after all major work on the Brake System, in some cases the Brake Electronics Control Module (J104) may automatically require this Function Test and set the correlating Fault Code 01486.
  • Once the Function Test has been started it cannot be cancelled and must be successfully finished.


Prerequisites

  • Vehicle stationary
  • Ignition ON, Engine ON (Running)
  • Perform the Test Drive on an enclosed Site (i.e. a Parking Lot)
  • Make sure to Complete the Function Test within 50 Seconds after pressing the Brake Pedal


Instructions

  • Firmly press the Brake Pedal until a certain Brake Pressure (usually right above 30 bar) is reached
  • The Brake Pressure Sensor (G201) Plausibility Check will be confirmed by a Change in the Brake Electronics Warning Lights.
    • On Bosch, the ASR/ESP Warning Light (K155) will switch OFF and the ABS Warning Light (K47) will switch ON.
    • On Continental/Teves, the ABS Warning Light (K47) will switch OFF and the ASR/ESP Warning Light (K155) switch ON.
  • TBC


Special Notes

  • If you are experiencing Problems getting the Function Test carried out please contact us directly, our Techs have a vast Experience with this Subject and will gladly assist you with the Process. ;-)


TO BE REMOVED ONCE DONE

  • 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.
