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 group "General". 
      5. 2.4.5 Select the actual value "Engine speed and engine torque". 
      6. 2.4.6 Select the "Misfiring"  group.
      7. 2.4.7 Note the actual value "Segment adaptation for rough running, status"  .

         Value "0" = adapted and (value "2" = not adapted) 1) 

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

         A journey with at least 11 cycles (acceleration => overrun) until the adaptation status changes. 1)  .

      9. 2.4.9 Set the operating temperature of the combustion engine.
      10. 2.4.10 Set "Normal" drive mode (for hybrid vehicles "Hybrid Auto") with "Manual" transmission mode in 2nd gear.
      11. 2.4.11 Hold engine speed between 1, 600 and 2, 400 rpm.
      12. 2.4.12 Generate a minimal load (50 to 150 Nm/37 to 111 ftlb.) → slight acceleration or maintain 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.

¹⁾ The status "Segment adaptation for running smoothness" is not displayed for various vehicle types and cannot therefore be checked. Sender wheel adaptation must still be carried out according to specifications.
