Result

Cause Of Fault
E001 Result: Defective Component
  • Defective component:
    B77 Sensor - Sun Intensity & Passenger Compartment Temperature
E002 Result: Defective Component
  • Defective component:
    A1_A14 Control Unit - Climate Control

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: Interruption
  • Short circuit to voltage/interruption of circuit between:
    A1_A14 Control Unit - Climate Control
    Wiring harness connector (wiring harness side) terminal 10 (XC42)
    &
    B77 Sensor - Sun Intensity & Passenger Compartment Temperature
    Wiring harness connector (wiring harness side) terminal 3

or

  • Defective component:
    A1_A14 Control Unit - Climate Control

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 Voltage/Ground/Interruption
  • Short to voltage/ground/interruption of circuit between:
    A1_A14 Control Unit - Climate Control
    Wiring harness connector (wiring harness side) terminal 21 (XC42)
    &
    B77 Sensor - Sun Intensity & Passenger Compartment Temperature
    Wiring harness connector (wiring harness side) terminal 1

or

  • Defective component:
    A1_A14 Control Unit - Climate Control
