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.
E003 Result: Short to Voltage
  • Short circuit to voltage between:
    A84 Control Unit - Engine
    Wiring harness connector (wiring harness side) terminal 55 (XC1)
    &
    B69 Air Mass Meter
    Wiring harness connector (wiring harness side) terminal 1

or

  • Defective component:
    A84 Control Unit - Engine

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: Short to Ground/Interruption
  • Short circuit to ground/interruption of circuit between:
    A84 Control Unit - Engine
    Wiring harness connector (wiring harness side) terminal 55 (XC1)
    &
    B69 Air Mass Meter
    Wiring harness connector (wiring harness side) terminal 1

or

  • Defective component:
    A84 Control Unit - Engine

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.
