Adaptation of the throttle unit

Checking diagnostic trouble codes (DTCs)




- Ignition on
- Read off diagnostic trouble codes (DTCs).
Check to see if any diagnostic trouble codes (DTCs) are stored. Any other diagnostic trouble codes (DTCs) may mean that adaptation of the engine control module (ECM) is not possible.





Are other diagnostic trouble codes (DTC) stored?

Yes - Fault-tracing information

No - Adaptation of the throttle unit

-------------------------------------------------

Adaptation of the throttle unit

Note! The ignition must be switched on for at least 30 seconds after the basic conditions are met in order for the adaptation to start. It takes approximately 10 seconds to run the adaptation.




- Ignition off
- Ignition on
- Read off the parameters.
Check that the following basic conditions for adaptation of the throttle unit are met.
1. Ignition on / engine off
2. Battery voltage above 10 V
3. Accelerator pedal (AP) unaffected
4. The car must be stationary (no vehicle speed signal)
5. Engine coolant temperature (ECT) between 5-100 °C
6. Intake air temperature (IAT) above 5 °C.
Remedy as necessary.
Check that the adaptation is correctly run after the "Adaptation of the throttle unit running" parameter changes status from "YES" to "NO". When all basic conditions are met, the adaptation must be completed after approximately 40 seconds. When the adaptation is completed correctly, the following information will be displayed:
- Adaptation of the throttle unit: OK
- Adaptation of the throttle unit running: NO.
