DOOR LOCK <COLT CZ3/CZT>
Door lock has been adopted. There are the following features.
- A central door locking system that locks and unlocks all doors (including the tailgate) via the driver’s door key cylinder or the driver’s door inner lock knob is optionally available.
- Key-in prevention function has been introduced.
- Direct combination key cylinder mechanism has been adopted.
- Free wheel key cylinder has been adopted.<RH drive vehicles>
- Dead lock system has been adopted optionally <RH drive vehicles> (Refer to
).
DESCRIPTION OF STRUCTURE AND OPERATION
CENTRAL DOOR LOCKING SYSTEM
- All doors (including the tailgate) are locked when all of them are closed and the driver’s door key cylinder or the driver’s door inner lock knob is operated to the locking direction.
- The driver’s door can be opened by pulling the driver’s door inner handle even when the driver’s door inner lock knob is in the locked position. This function is called "Override function".
When the driver’s door is locked (when the lock switch turns ON after turning OFF the unlock switch in the driver’s door lock actuator), ETACS-ECU turns ON the lock relay output for 0.26 second, and locks all doors (including the tailgate). When the driver’s door is unlocked (when the unlock switch turns ON after turning OFF the lock switch on the driver’s door lock actuator), ETACS-ECU turns ON the unlock relay output for 0.26 second, and unlocks all doors (including the tailgate).
KEY-IN PREVENTION FUNCTION
When the driver’s inner lock knob is operated to the lock position with the driver’s door open, the driver’s door cannot be locked, thus preventing it from being locked with the key inside the vehicle.
DIRECT COMBINATION KEY CYLINDER MECHANISM
This mechanism allows the doors not to be locked easily during side collision. Because of this, the doors can be opened after side collision.
- Even if any door key cylinder is attempted to be tampered with the doors locked, the tampering force is not easily transmitted to the door latch to deter thieves.
FREE WHEEL KEY CYLINDER <RH DRIVE VEHICLES>
A clutch has been adopted inside the key cylinder of the doors. This prevents the force to open the doors using items other than the key when the vehicle is locked from being transferred to the key cylinder and latch joint so that the theft-prevention performance has been improved.
- The retainer with stopper has been adopted to the door key cylinder to prevent improper removal of the key cylinder from outside the vehicle.
