To lock with the remote control - press button A once and all the doors will be locked.

When the button on the remote control is pressed, it transmits a signal to the receiver. The receiver processes the signal and transmits it to the TWICE control module.

A short voltage pulse (0.8 sec.) is output from pin 22 on the TWICE control module to the doors' electric motors, which locks the car.

The lock motors are grounded to the TWICE control module by

• pins 26 and 42, driver's door
• pins 69 and 66, passenger door
• pins 49 and 20, rear doors
