ESP Off Indicator Lamp

ESP OFF Indicator Lamp








If a fault should occur in the ESP system, the ESP OFF indicator lamp will be turned on via the Pbus. The warning lamp also comes on when the system is disengaged manually, which can be done at speeds lower than 60 km/h (37.5 mph) by pressing the ESP switch. The system can be engaged by pressing in the ESP switch at an optional speed, whereby the ESP OFF indicator lamp will go out again.


When the ignition is turned on, the lamp comes on; if there is no fault, the lamp goes off again after 3-5 seconds.


Diagnosis

If there is a fault in a system which affects the ABS function then the ABS, ESP OFF and foot brake warning lamps will light up.


If there is no bus message from the ESP control module for 2 seconds, the ESP OFF and ABS lamps will light up. If there is no bus message for a further 8 seconds, the foot brake fault warning lamp will also come on.
