The wiper motor is a 12 V motor with transmission. The control unit, wiper
motor and the transmission
form one complete unit. This wiper motor unit consists of:
- A permanently excited direct current motor with attached reduction gear.
- Control unit electronics with eccentric shaft sensor with attached plug
connection.
The control unit in the wiper motor is able to identify the following faults:
- Faults in the control unit electronics.
- Short circuits at the motor and sensor system.
- Open lines at the motor and sensor system.
The control unit in the wiper motor does not have a fault memory. The fault
code entry is stored in the
Body Domain Controller (BDC).
The heated washer jets are activated by the Body Domain Controller.
The Body Domain Controller is also responsible for actuation of the windshield
washer pump and
evaluation of the washer fluid level switch.
