Brown and brown/white
I
NOTE
Both these cables must only be connected when there is an analogue
connection.
They are not required for the CAN bus connection. In this case, insulate
the ends and store them.
➤ Connect the brown cable and the brown/white cable to the brake light switch
(fig. 9 1, page 7).
If there are more than two cables leading from the brake light switch, this is how to
identify the two cables you need:
➤ Use a voltmeter to measure the voltage on the cables.
One of the two original cables on the brake light switch should have a
permanent positive voltage (terminal 30, 12 V) or a connected positive voltage
(terminal 15).
The second original cable should have a voltage of +12 V when the brake is
applied. As soon as the brake pedal is released, no more voltage should be on
that cable.
If you cannot measure a full +12 V on the brake light switch, you vehicle probably has
a digital brake system.
In this case, connect the two cables as follows:
➤ Connect the brown/white cable to a fuse-protected, connected positive
terminal (terminal 15).
➤ Connect the brown cable to the original cable leading to the brake lights.
The voltage on this cable is +12 V with the brake applied, and 0 V with the brake
released. You will find these cables directly at the rear lights or in the wiring
harness at the rear of the vehicle.
