Locking and unlocking tailgate (3 and 5-door bodies): Unlock
+30 voltage is supplied via fuse 25 to pin 47 on the TWICE control module.
Switch 388 on the driver's door feeds, when activated, ground to TWICE control module pin 11. In turn, the control module outputs a short impulse from pin 67 to the tailgate lock motor (184H), and the tailgate is opened.
When switch 622 is activated by the key being turned, ground is fed to pin 59 on the TWICE module which in turn outputs a voltage impulse via pin 67 to the tailgate lock motor 184H. The tailgate is unlocked and can be opened with the tailgate handle.
The tailgate can also be unlocked with the remote control. The aerial unit feeds, when receiving a signal, ground to TWICE control module pin 51.
When the tailgate is opened, the switch for luggage compartment lighting is closed, which in turn contacts the TWICE control module. TWICE sends a bus message "TAILGATE OPEN" when the tailgate is open. This is used by the main instrument that lights up lamp 213j door indication, tailgate (pictogram).
The tailgate lock motor 184H is grounded on the control module pins 2 and 44. Switch 622 is grounded in grounding point G3.
The aerial unit is grounded in grounding point G33P on LHD cars, and in grounding point G34S on RHD.
Switch 388 is grounded in grounding point G35 on LHD cars, and in grounding point G24 for RHD.
