2	ESP warning lamp -K155-
3	Brake system warning lamp -K118-

ABS warning lamp -K47-

t  If the ABS warning lamp -K47--1- does not go out after the ignition has been switched on and test sequence has been completed, then the fault may be: -a- The voltage supply is below 10 volts. -b- There is a fault in the ABS. In the event of an ABS fault -b-, the anti-lock brake system remains switched off, but the brake system remains fully operational. -c- A temporary speed sensor fault occurred since the vehicle was last started. In the case of a speed sensor fault -c-, the ABS warning lamp -K47- will extinguish automatically after restarting the engine and attaining a speed of above 2.75 km/h (approx. 13 mph). -d- The connection from dash panel insert to ABS control unit -J104- is interrupted. → Current flow diagrams, Electrical fault finding and Fitting locations ABS warning lamp -K47- and brake system warning lamp -K118-

t  If the ABS warning lamp -K47--1- goes out but the brake system warning lamp -K118--3- remains on, the causes of the fault may be: -a- The handbrake is applied. -b- The brake fluid level is too low. -c- There is a fault in the activation of the brake system warning lamp -K118-. → Current flow diagrams, Electrical fault finding and Fitting locations t  If the ABS warning lamp -K47--1- and the brake system warning lamp -K118--3- light up, the anti-lock brake system and the EBPD (electronic brake pressure distribution) system have failed.   WARNING After the ABS warning lamp -K47- and the brake system warning lamp -K118- have lit up, it is possible that the rear wheels will lock up earlier. ESP warning lamp -K155- Only in vehicles with ESP.

t  If the ESP and TCS warning lamp -K155--2- does not go out after ignition is switched on and the test sequence has been completed, then the fault may be: -a- Short-circuit to positive in TCS and ESP button -E256-. -b- There is a fault in the activation of the ESP and TCS warning lamp -K155- → Current flow diagrams, Electrical fault finding and Fitting locations. -c- The TCS/ESP system was switched off by the TCS and ESP button -E256-. A fault in the system affecting only the TCS/ESP. The ABS/EDL and EBD safety systems on the vehicle remain fully functional ⇒ Read fault memory. If the ESP warning lamp -K155- flashes while the vehicle is in motion, the TCS or ESP is in operation.
