Notes on trouble-shooting - Tire pressure warning system
Aids
Use 1 or 2 auxiliary cables (own construction)
for measurements on the control unit connec-
tors and plug connections with the same con-
tacts (flat contacts). This will prevent the con-
tacts becoming deformed.
1 - Highly flexible line
2 - Crocodile clips (standard)
3 - Flat connector 2.8 (N 17.457.2)
Combined plug connections - distin-
guishing line features
There are several combined plug connections
of the same type in the lines for brake-pad
wear, speed sensors and HF sensors. The
lines in this area can be distinguished from
one another as follows:
Sheathed lines for
HF sensors and speed sensors.
For brake-pad wear: 2 lines protected by
tubing.
The HF sensor connectors have 1 pin and
1 socket. The connectors for the speed
sensors have 2 pins with 2 sockets on the
other side.
There are 2 combined connectors on top
of one another in the area of the spare
wheel. The lines here are marked with RL -
rear left and HR - rear right.
