Locking all doors
WARNING: This page is about a different car, the 2001 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
The central locking system can be operated with the key from the driver's door.
All doors can be locked by turning the key once clockwise (LHD) or anticlockwise (RHD).
When the key is turned in the lock, a microswitch in the lock unit closes, microswitch pin 6 is grounded and accordingly pin 56 of the TWICE control module is also grounded.
A short voltage pulse is fed from control module pin 22 to the lock motors in the doors, and the doors lock.
The lock motors are grounded in the TWICE control module on:
- Pin 26 and 42, driver's door (5D, 3D and Convertible)
- Pin 66 and 69, passenger door (5D, 3D and Convertible)
- Pin 49 and 20, rear doors (5D)
