Teaching in components in the vehicle
Is a new component causing problems? Does the error lamp go on after replacing a component in the vehicle? How do you adapt a new component in the vehicle? How do you teach in spare parts in the vehicle? This video gives you the answers.
Has your car recently been to the repair shop and had a component replaced? And is exactly this component supposedly still causing problems? Then it is possible that the part has not been adapted (“taught in”).
Here, you can learn how it works:
For many components in a vehicle, the map data that is required for optimal operation must be “learned” by the engine control unit. Some of these are, for example:
- throttle valves
- air mass sensors
- idle controllers
- electric EGR valves
- servo motors
After these components have been replaced, it must be communicated to the control unit that a new part has been installed, for which the old map data no longer applies. Otherwise, problems can arise, or the error lamp can go on.
There are different ways of carrying out the adaptation:
Method 1: with an engine tester
This is the quickest and easiest method. It is carried out via a special program item in the device’s menu, e.g. “Throttle valve basic settings”. This method is recommended by Motorservice.
Method 2: with a test run
In a test run of at least 15 minutes, the map data can gradually be replaced by the new values. Therefore, to begin with, the problems described may arise. However, they will decrease.
Other methods are described in the video.
