Result

Cause Of Fault

• A temporary current overload in the system behind fuse FE9 has occurred
  or
  Defective component:
  K7_X125 Relay - Washer Pump, Headlamps

Note:

In case of a temporary current overload, the cause for the blow of the fuse may be located in a circuit behind the control unit/component.

These circuits should be checked additionally for short to ground.

• If the nominal value is reached during one of the measurements, the component/control unit that has been disconnected immediately before that measurement is defective.

• Short circuit to ground between:
  X125 Underhood Electronic Module
  Socket Terminal 46 (XE1)
  &
  Y106 Pump - Washer, Headlamps
  Wiring harness connector (wiring harness side) terminal 1

or

• Defective component:
  Y106 Pump - Washer, Headlamps

• Defective component:
  K7_X125 Relay - Washer Pump, Headlamps
  or
  X125 Underhood Electronic Module

Important:

Reset the concerned control unit with the diagnostic tester before replacing it. In order to do that, call up the "RESET" function from the PROGRAMMING menu of the current system on the diagnostic tester.

Note:

The replacement of the components must be done in the listed order.

The system must be checked for proper operation after every replacement.

-

If the defective component is a switching device (e.g. switch or relay) or a fuse, the cause for the fault may be located in the circuit behind that component.
In case of a switching device, the corresponding part of the circuit should be checked for short to ground/voltage before replacing the component.

• A temporary current overload in the system behind fuse FE9 has occurred

Note:

In case of a temporary current overload, the cause for the blow of the fuse may be located in a circuit behind the control unit/component.

These circuits should be checked additionally for short to ground.

• Defective component:
