Result

Cause Of Fault
E001 Result: Defective Component
  • Defective component:
    Y56 Solenoid Valve - Exhaust Gas Recirculation
    or
    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.

Note:

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

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

    &
    Y56 Solenoid Valve - Exhaust Gas Recirculation
    Wiring harness connector (wiring harness side) terminal 5
E003 Result: Short to Ground
  • Short circuit to ground between:
    A84 Control Unit - Engine
    Wiring harness connector (wiring harness side) terminal 15 (XC19)
    &
    Y56 Solenoid Valve - Exhaust Gas Recirculation
    Wiring harness connector (wiring harness side) terminal 5
E004 Result: Short to Voltage
  • Short circuit to voltage between:
    A84 Control Unit - Engine
    Wiring harness connector (wiring harness side) terminal 15 (XC19)
    &
    Y56 Solenoid Valve - Exhaust Gas Recirculation
    Wiring harness connector (wiring harness side) terminal 5

    Wiring harness connector (wiring harness side) terminal 1

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.
E006 Result: Defective Component
  • 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.
