Result

Cause Of Fault

E001 Result: Defective Component
  • Defective component:
    B69 Air Mass Meter
    or
    A84 Control Unit - Engine

Important:

After replacing the following component the programming function for the replacement of the corresponding component has to be performed by using the diagnostic tester:

B69 Air Mass Meter

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.

E002 Result: Short to Voltage
  • Short circuit to voltage between:
    A84 Control Unit - Engine
    Wiring harness connector (wiring harness side) terminal 42 (XC11)
    &
    B69 Air Mass Meter
    Wiring harness connector (wiring harness side) terminal 4

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.

E003 Result: Short to Ground/Interruption
  • Short circuit to ground/interruption of circuit between:
    A84 Control Unit - Engine
