+
<sup>2</sup> 5F Infotainment / Information Control Unit

<sup>3</sup> 19 – CAN Gateway with SFD2 diagnostic filter
==== Prerequisites ====
 
* Engine must be running
 
* All electrical consumers OFF (A/C, headlights, rear defrost, seat heaters, etc.)
 
* No active Diagnostic Trouble Codes (DTCs) Clear all fault codes prior to starting the test
 
* Engine coolant temperature must be at least 80°C (176°F)
 
* <span style="color:red;">Must be performed outside or in a well vented area only!</span>
 
 
 
==== Workshop Procedure with VCDS ====
 
 
 
* Connect to the vehicle using VCDS.
 
 
 
* Go to '''[01 - Engine]'''
 
 
 
* Check for and clear any fault codes.
 
 
 
* Click on the '''[Basic Settings]''' button.
 
 
 
* Select '''[Automatic test sequence]''' or '''[Automatic test procedure]''' from the available list.
 
 
 
* Click on the '''[Show Measuring Data]''' checkbox and include the following Measuring Values:
 
 
 
  {| class="wikitable"
 
  |-
 
  ! Measuring Value !! Description
 
  |-
 
  | IDE00450 || '''Operating Instructions''' – ''Follow all prompts provided here''
 
  |-
 
  | IDE00451 || '''Currently Running Routine''' – ''Indicates the test currently in progress''
 
  |-
 
  | IDE00030 || '''Status of Actuator Test''' – ''Displays overall status of test procedure''
 
  |-
 
  | IDE00727 || '''Test Steps Still to Be Performed''' – ''Should count down to 0 when complete''
 
  |-
 
  | IDE00021 || '''Engine Speed''' – ''Follow any required RPM prompts shown in Operating Instructions''
 
  |-
 
  | IDE00025 || '''Coolant Temperature''' – ''Should be at or above 80°C before beginning''
 
  |}
 
 
 
* Click the '''[Go]''' button to begin the Basic Setting procedure.
 
 
 
* When prompted, '''press and hold both the brake and accelerator pedals simultaneously.''' Keep them pressed until the test finishes.
 
 
 
* When the test completes successfully, the '''IDE00450 [Operating Instructions]''' field will display: 
 
  ''''System OK''''  or  ''''Finished correctly''''
 
 
 
 
 
==== Special Notes ====
 
 
 
# The duration of the Automatic Test Sequence may vary depending on vehicle platform and engine type.
 
# If the sequence fails or does not complete, verify that all prerequisites are met, especially coolant temperature and fault-free status.
 
# This function is only available in UDS-based engine control modules. Non-UDS controllers use a different Readiness procedure, see Repair Manual.
 
# If the [Go] button is grayed out or unavailable, ensure that the engine is running and that the selected test is supported by the ECU.
