Operation







OPERATION

POWER DOOR LOCKS

All doors can be locked or unlocked electrically by operating the switch on either front door panel.

The rear doors can be locked or unlocked by actuation of the front door switch, or can be locked or unlocked mechanically and independently with their respective locking knobs.

The front doors can be locked or unlocked mechanically with the locking knob regardless of electrical locking and unlocking actuation with the front door knobs.

The left front door on all vehicles can be locked or unlocked mechanically from the outside with the key or electrically as described above. The left and right front doors can also be unlocked by actuation of the inside remote door handle.

AUTOMATIC DOOR LOCKS

The CCN controls the power locks when the door lock switch is activated. If the door lock switch is pressed for longer than eight consecutive seconds, the CCN will de-energize the door lock relay.

The automatic door lock system can be enabled/disabled either by the customer or with the scan tool. Refer to the scan tool or the vehicle owners manual for enabling/disabling procedures.

The CCN will automatically re-lock all doors if the above conditions are met and if any of the doors become ajar and then closes again.

The power latches are also equipped with a thermal protection system which prevents the latches from burning out.

CHILD PROTECTION LOCK

The lock when engaged, will disable the inside door handle from opening the door. The lock is part of the latch/lock assembly. The lock is engaged by moving a lever that is located on the rearward inside edge of the door.

DOOR LOCK INHIBIT

With the key in the ignition switch in the ON or OFF position and the driver's door open the CCN will ignore the command to lock the power door locks. Once the key is removed, or the driver's door is closed, the CCN will allow the power door locks to lock.

REMOTE KEYLESS ENTRY

The transmitter has four buttons for operation. They are LOCK, UNLOCK, DECK LID RELEASE, and PANIC.

- The UNLOCK button will unlock the driver's door and enable illuminated entry. Pushing and releasing the button once will unlock the driver's door. Pushing and releasing the button two times, within a five second interval, will unlock all doors.The unlock sequence can be toggled between driver door first and all door unlock functions.
- Upon pressing the LOCK button, the horn will sound a short CHIRP (if enabled) and flash the park lamps to notify that the all door lock signal was received and set. Illuminated entry is cancelled and the interior lamps are faded to off.
- DECK LID RELEASE - The Deck Lid release button changes from a default "press twice" actuation to a "press and hold" (for approximately one third of a second) default. Note that this is customer programmable to "no delay" if so desired.
- Pushing and holding the PANIC button will cause the panic alarm to sound for three minutes, until the panic button is pressed and held a second time, or the vehicle reaches a speed of 15 mph.

The receiver is capable of retaining a Vehicle Access Code (VAC) even when power is removed.

Each Remote Keyless Entry (RKE) module must have at least one and no more than four transmitters.

HORN CHIRP TOGGLE

This can be done using a scan tool or by the customer. The horn chirp will enter the opposite state of its current programmed state by receiving this operation code. The CCN is responsible for keeping track of the horn chirp status.
