It appears to be a ``shift position detection error' ' .
I see, i see.
If so, use the MAXISYS status function.
I will monitor the ECU's shift position detection.

Selector lever position = 8
Selected gear = 4
It becomes.
If you move this to the D range
Selector lever position = 11
Selected gear = 4
On the selector lever side and transmission side
Each is equipped with a sensor for position detection.
I can recognize the change in the position of the selector lever.

Selector lever position = 8
Selected gear = 1

Selector lever position = 5

In the current generation, this sensor is often incorporated inside the mission.
There are quite a lot of troubles in this generation of German cars where it is externally installed.
