Car Information:
Mercedes Benz SL 500
Year: 1998
Engine Size: V8
Trans: Automatic

Issue / Question:
@ 20 mph doors lock, However when exiting the car, can’t open doors from inside using door handle on either side of the car. Must put trans in PARK, key out of ignition,and press the unlock button door will unlock.

This is very complex, it uses vacuum and electric to operate this system. We would need to scan the system first and see if we can manually input commands through the door lock control units (there’s 2) one for the electrical portion and one for the vacuum part. If we can do the inputs it may be a range switch, or even a vacuum leak.
