ESP system sensors and components,
description
Control module for ABS with EDL/ASR/ESP -
J104-
The control module is combined with the
hydraulic unit as one unit. It controls the ESP,
ABS, EDL, ASR, EBD and ETR (Engine Torque
Reduction) functions. When ignition is switched
on, the control module performs a self-test. All
electrical connections are monitored constantly
and the solenoid valves are periodically checked
for function. If the control module fails entirely,
only the normal brake system will be available.
Steering angle sensor -G85-
The steering angle sensor is housed together
with the airbag spiral spring/return spring with
slip ring. It is located on the steering column
between the steering column switch and steering
wheel. It transmits the steering wheel's steering
angle to the ABS control module -J104 for
ABS/ASR/ESP via the CAN-bus. After replacing
the control module or the sensor, a zeroing must
be performed. For malfunctioning sensor, the
ESP function is not available.
