| − | === 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.'''

| |
| − | * 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.''
