Result

Cause Of Fault
E001 Result: Defective Component
  • Defective component:
    B176 Sensor - Rail Fuel Pressure
    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.

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

B176 Sensor - Rail Fuel Pressure

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/Ground/Interruption
  • Short to voltage/ground/interruption of circuit between:
    A84 Control Unit - Engine
    Wiring harness connector (wiring harness side) terminal 38 (XC19)
    &
    B176 Sensor - Rail Fuel Pressure
    Wiring harness connector (wiring harness side) terminal 2

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 Voltage/Interruption
  • Short circuit to voltage/interruption of circuit between:
    A84 Control Unit - Engine
    Wiring harness connector (wiring harness side) terminal 6 (XC19)
    &
    B176 Sensor - Rail Fuel Pressure
    Wiring harness connector (wiring harness side) terminal 1

or

  • Defective component:
