Unlocking 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.
To unlock, turn the key once anticlockwise (LHD) or clockwise (RHD).
When the key is turned in the lock, a microswitch is closed and the lock unit is grounded to microswitch pin 4 and accordingly pin 33 (driver's door LHD) or pin 8 (driver's door RHD) of the TWICE control module is also grounded.
The TWICE control module outputs a short voltage impulse from the following pins:
- 26 to lock motor, driver's door (5D, 3D and Convertible)
- 69 to lock motor, passenger door (5D, 3D and Convertible)
- 49 to lock motors, rear doors (5D)
The lock motors are grounded in the TWICE control module on:
- 42 and 22, driver's door lock motor (5D, 3D and Convertible)
- 66 and 22, passenger door lock motor (5D, 3D and Convertible)
- 20 and 22, rear door lock motors (5D)
