Result

Cause Of Fault
E001 Result: Defective Component
  • Defective component:
    B28I Sensor - Camshaft, intake
    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.
