ABS BOSCH 8.2/8.2i Dash panel insert

Different versions of the dash panel insert according to the vehicle equipment → electronic catalogue of original parts Warning lights

Pos.	Denomination
1	Warning light 2 for ESP and TCS -K216-
2	ABS warning light -K47-
3	ESP and TCS warning light -K155-
4	Dual circuit and hand brake system warning light -K7-
5	Warning light for tyre pressure display -K220-

Warning light 2 for ESP and TCS -K216- If the TCS system is switched off in the centre console using the TCS and ESP button -E256-, the warning light 2 for ESP and TCS -K216--1- must light up when the ignition is switched on. t  If the warning light 2 for ESP and TCS -K216--1- does not light up when the TCS system is switched off in the centre console using the TCS and ESP button -E256- and the ignition is switched on, this may be due to the following cause: -a- the connection of the dash panel insert to the ABS control unit -J104- is interrupted → Current flow diagrams, Electrical fault finding and Fitting locations   Note t  Only the TCS system can be switched off using the TCS and ESP button -E256-. t  The ESP system cannot be switched off, i.e. the ESP system always remains active. ABS warning light -K47- t  If the ABS warning light -K47--2- does not go out after switching on the ignition and the completion of the test, this may be due to the following causes: -a- the supply voltage is less than 10 V -b- an ABS fault is present If an ABS fault -b- is present, the anti-lock brake system remains switched off while the conventional brake system remains fully operational. -c- a sporadic fault existed on a wheel speed sensor after the last vehicle start In case of a wheel speed sensor fault -c-, the ABS warning light -K47- goes out automatically after restarting the engine and after a speed above 2.75 km/h is reached. -d- the connection of the dash panel insert to the ABS control unit -J104- is interrupted → Current flow diagrams, Electrical fault finding and Fitting locations ABS warning light -K47- and dual circuit and hand brake system warning light -K7-

t  If the ABS warning light -K47--2- goes out, however the dual circuit and hand brake system warning light -K7--4- remains lit up, this may be due to the following causes: -a- the hand-brake is applied -b- the brake fluid level is too low -c- Voltage supply for the dual circuit and hand brake system warning light -K7- → Current flow diagrams, Electrical fault finding and Fitting locations t  If the ABS warning light -K47--2- and the dual circuit and hand brake system warning light -K7--4- remain lit up, there is a failure in the ABS and EBD systems (electronic brake pressure distribution).   Caution Once the ABS warning light -K47- and the dual circuit and hand brake system warning light -K7- have lit up then the rear wheels lock quite early on when braking. ESP and TCS warning light -K155- only on vehicles with ESP

t  If the ESP and TCS warning light -K155--3- does not go out after switching on the ignition and the completion of the test, this may be due to the following causes: -a- short circuit to positive in TCS and ESP button -E256- -b- voltage supply for the ESP and TCS warning light -K155- defective → Current flow diagrams, Electrical fault finding and Fitting locations -c- the TCS/ESP system was switched off using the TCS and ESP button -E256- There is a fault which exclusively effects the TCS/ESP safety system. The ABS/EDL as well as EBD safety systems of the vehicle remain fully functional ⇒ Interrogate fault memory → Vehicle diagnostic tester. If the warning light for ESP and TCS -K155- flashes while driving, the TCS or the ESP system is operating in regulating mode.

Warning light for tyre pressure display -K220- (-5-) t  Warning light for tyre pressure inspection display -K220- (-5-) comes on: –  Carry out tyre pressure inspection. –  Correct the nominal pressure of the tyre. –  Perform basic setting. Initiating basic setting: l  Ignition on

–  Press the button for tyre pressure inspection -E226--arrow- for more than 2 seconds. The button is located in the left centre console of the hand-brake lever. When the button for tyre pressure inspection -E226- is pressed the warning light for tyre pressure inspection display -K220- lights up in the dash panel insert. The basic setting is confirmed with an acoustic signal. –  Switch off ignition. –  After the ignition is switched on again, the warning light for tyre pressure inspection display -K220- does no longer light up. t  Warning light for tyre pressure inspection display -K220- flashes: –  Carry out tyre pressure inspection. –  Correct the nominal pressure of the tyre. l  Ignition on

–  Press simultaneously the button for tyre pressure inspection -E226--arrow- and the TCS and ESP button -E256- or traction control system switch -E132- for more than 2 seconds (Fitting location of the button: in the left centre dash panel next to the heater control). If the warning light for tyre pressure inspection display -K220- continues to flash: –  Carry out „Targeted fault finding“ with vehicle diagnosis, measurement and information system -VAS- → Vehicle diagnostic tester.
