Operation

The mechanism of the ignition lock interlock connects the selector lever of the floor shift with the ETC control module (N73). It prevents the transmitter key (A8/1) from being withdrawn when the selector lever is not at position "P".

When the parking lock is not engaged (selector lever position "D", "R", "N"), the locking valve (60) locks the locking cam (61). The compression spring (62) only pulls the locking valve (60) away from the locking cam (61) in selector lever position "P". The transmitter key (A8/1) can now be turned to position "0" and removed from the ignition.
