Note:
After confirming input of display group 60, adaptation is started. The
Throttle Position (TP)sensor is positioned in the closed throttle, wide
open throttle and limp-home positions. Following this procedure, other
intermediate steps will create a characteristic curve of the relationship
between Throttle Position (TP) sensor -G69- and angle sensor for
throttle drive -G187-. The Motronic ECM stores these values in permanent memory.
Afterward, the throttle valve assumes the starting position.
