Result

Cause Of Fault
E001 Result: System Overload
  • A temporary current overload in the system behind fuse FE28 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.
E002 Result: Defective Component
  • Defective component:
    A112 Control Unit - Transmission

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:

If the defective component is a control unit, the cause for the fault may be located in a circuit behind that component.
E003 Result: Short to Ground
  • Short circuit to ground between:
    X125 Underhood Electronic Module
    Socket Terminal 19 (XE3)
    &
    Wiring harness connector terminals of all components (wiring harness side), which were disconnected from the wiring harness during this troubleshooting session

or

  • Defective component:
    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.
E004 Result: Defective Component
  • 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.

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:

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