Overwriting Adaptation Values: Information
Consequences of Tester adaptation if conditions for automatic adaptation are not met (violated boundary condition):
- For a fault entry in the load detection range (P0068 + P1069... P1077), the limits are extended in order to prevent incorrect detections.
- This extension is cancelled if an adaptation is performed when the conditions for automatic adaptation are met, or after 15 warm-up cycles at the latest
- (Warm-up cycle = coolant temperature increases by more than 23 °C (73 °F) after start-up and reaches at least 73 °C (163 °F))
- Following manual throttle valve adaptation when ambient conditions are not met, throttle valve adaptation is carried out again automatically as soon as the ambient conditions are met.
- There is NO 30-second waiting time here, but a slightly delayed engine start is possible once.
- The ambient conditions for automatic adaptation are as follows:
Engine off and ignition on for > 30 seconds.
Accelerator pedal is not pressed.
Vehicle is stationary.
Power supply for throttle valve adjusting unit is OK.
Coolant temperature 5 °C... 100 °C (41 °F... 212 °F)
Intake air temperature 5 °C... 40 °C (41 °F... 104 °F)
The accelerator pedal must always be pressed after approx. 1.5 minutes since each adaptation step is limited to 5 Nm.
