Subsequent Work For Diagnostic Scopes

Information 

• After removing, installing or replacing, perform the "Sensor wheel adaptation" function using the PIWIS Tester. 
• To actively teach the adaptation, perform an adaptation drive together with another person. 

1. Only for R4:
   1. 1.1  Connect PIWIS Tester  to the vehicle.
   2. 1.2  Select Engine electronics (DME) control unit  .
   3. 1.3  Select Maintenance/Repairs  tab.
   4. 1.4  Perform sensor wheel  adaptation.
   5. 1.5  Follow the instructions on the PIWIS Tester  .
2. Only for V6T and V8T:
   1. 2.1  Select Engine electronics (DME) control unit  .
   2. 2.2  Select Maintenance/Repairs  tab.
   3. 2.3  Perform Sensor wheel adaptation reset  .
   4. 2.4  Perform sensor wheel adaptation by performing an adaptation drive  .
      1. 2.4.1 Get a second person to check the PIWIS Tester  while you are driving.
      2. 2.4.2 Select Engine electronics (DME) control unit  .
      3. 2.4.3 Select the "Actual values/input signals"  tab.
      4. 2.4.4 Select the service information "General"  .
      5. 2.4.5 Select the actual value "Engine speed and engine torque"  .
      6. 2.4.6 Select the "Misfiring"  service information.
      7. 2.4.7 Observe actual value "Segment adaptation for rough running, status"  .

         Value "0" = adapted and (value "2" = not adapted)

      8. 2.4.8 Perform adaptation drive until the actual value segment adaptation to running irregularity status  displays "0"  → Adaptation is complete  .

         This procedure must be carried out at least 11 x. 

      9. 2.4.9 Restore combustion engine to operating temperature.
      10. 2.4.10 Set "Normal" drive mode with "Manual" transmission mode in 2nd gear.
      11. 2.4.11 Engine speed → 1600 and 2400 rpm.
      12. 2.4.12 Generate a minimal load (50 to 150 Nm/37 to 111 ftlb.) → slight acceleration or speed for at least three seconds each.
      13. 2.4.13 Overrun phase (accelerator pedal not pressed, no fuel injection) for at least two seconds each.
