Result

Cause Of Fault

• A temporary current overload in the system behind fuse F53 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.

• 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.

Note:

If the defective component is a control unit, the cause for the fault may be located in a circuit behind that component.

These circuits should be checked additionally for short to ground.

• Short circuit to ground between:
  F53 Fuse
