Unlocking of the doors is accomplished by pressing button B.

When the button on the remote control is pressed, it sends a signal that is received by a receiver. The receiver processes the signal and transfers it to the TWICE control module.

A short voltage impulse is fed from the TWICE control module pins:

• Pin 26, driver's door (5D, 3D and convertible)
• Pin 69, front passenger door (5D, 3D and convertible)
• Pin 49, rear doors (5D)

The lock motors are grounded in the TWICE control module on

• Pin 42 and 22, driver's door (5D, 3D and convertible)
• Pin 66 and 22, front passenger door (5D, 3D and convertible)
• Pin 20 and 22, rear doors (5D)
