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.
