Principles of Operation

PRINCIPLES OF OPERATION

Power Locks
The power locking/unlocking feature requests all of the vehicle doors, including the liftgate (if equipped), be locked or unlocked upon a customer request from any interior door lock control switch in the vehicle. Power locking and unlocking of the doors operates independently of the position of the ignition and vehicle speed. The power locking/unlocking feature locks all the doors when a lock request is provided from any door lock control switch. When the vehicle security module receives an unlock/lock command from any door lock control switch, the vehicle security module will activate relays internal to the module to supply the correct power and grounds for the door lock actuators.

Power Unlock Inhibit

NOTE: This feature is not enabled when the vehicle is delivered to the customer. If the customer requests this feature the module can be configured to enable this feature.

With the key in the off position, 20 seconds after electrically locked by the remote keyless entry (RKE) transmitter, RKE keypad, or the door lock control switch locked with door ajar, and all doors are closed, the door lock control switch UNLOCK button will be disabled if this feature is enabled. (The lock function will still operate.)

Deactivating/Activating Power Door Unlock Switch Inhibit

NOTE: The power door unlock switch inhibit feature needs to be enabled to perform the deactivating/activating power door unlock switch inhibit procedure.

This is customer configured. Steps 1 through 3 must be completed within 30 seconds.
1. Turn the key to ON, then press UNLOCK 3 times.
2. Turn the key to OFF, then press UNLOCK 3 times.
3. Turn the key to ON, within 5 seconds press LOCK 2 times.

The user will receive 2 horn chirps to indicate the system has been disabled or 2 chirps followed by a horn honk to indicate the system has been enabled.

Pressing LOCK 2 times again will toggle the door lock control switch inhibit feature state.

Turn the key OFF to exit the programming mode.

This feature can also be enabled/disabled using a diagnostic tool.

Autolock
Autolock feature locks all doors when all of these conditions are met:
- the key is in RUN/START, then
- the vehicle speed is less than 8 km/h (5 mph), then
- all doors are closed, then
- the brake is applied and then released, then
- when the vehicle speed reaches 8 km/h (5 mph) or higher

Relock feature locks all doors when all of these conditions are met:
- autolock has previously occurred, then
- the speed is below 8 km/h (5 mph), then
- any door is opened with the brake pedal applied, then
- all doors are closed again, then
- the brake is released, then
- when the vehicle speed reaches 8 km/h (5 mph) or higher

Autolock Enable/Disable - Using the RKE Keypad
A manual enable/disable mode allows the autolock feature to be turned off and on.

To enable or disable autolock using the RKE keypad:
1. Enter the 5-digit permanent entry code into the RKE keypad.
2. Within 5 seconds of entering the code, press and hold the 7/8 button on the keypad.
3. Within 5 seconds of Step 2, and while holding the 7/8 button, press the 3/4 button on the keypad and release it.
4. Within 5 seconds of Step 3, release the 7/8 button on the keypad. If the autolock feature is disabled, the horn will chirp once.

If the autolock feature is enabled, the horn will chirp once shortly and then sound a second time for a longer sound of the horn once the above sequence is completed.

Autolock Enable/Disable Using the Ignition Switch
Another way to turn the autolock feature off/on is by following this series of steps:
1. Close all doors.
2. Confirm that the key is in the OFF position.

3. NOTE: Steps 3 through 8 must be carried out within 30 seconds.

Turn the key from OFF to RUN.

4. Press UNLOCK 3 times.
5. Turn the key from RUN to OFF.
6. Press UNLOCK 3 times.
7. Turn the key from OFF to RUN. The enable/disable mode is now ready to accept program changes.
8. Press UNLOCK once to command the vehicle security module to toggle the autolock/relock feature OFF.
9. Press LOCK once to enter the command.
10. Verify that the horn chirps one time. There should only be one chirp indicating that the autolock/relock feature has been disabled. If one chirp is heard followed by a longer sound of the horn, the autolock/relock feature has just been enabled. Return to Step 10.
11. Turn the key to the OFF position to exit the enable/disable mode.

Smart Unlocking
The smart unlocking feature prevents the driver door from locking with the key in the ignition. When the vehicle security module receives a LOCK command from a door lock control switch, and the key is in the ignition with the driver door open, the vehicle security module will command the driver door to UNLOCK. The doors can be locked with the key in the ignition using either the RKE keypad or the RKE transmitter.

RKE Transmitter Lock/Unlocking Control - Unlocking
The remote control feature provides lock/unlock functions independent of ignition/speed/PRNDL state. The remote control feature provides a 2-step process for unlocking the doors. Upon receipt of the first request for unlocking the doors, the remote control feature requests the vehicle security module to unlock the driver door only. If another unlock request is received within 3 seconds of the first, the remote control feature will request that all doors be unlocked.

RKE Transmitter Lock/Unlocking Control - Locking
The remote control feature requests that all the doors be locked when the LOCK button is pressed. On any press of the lock button with all doors closed: the remote control feature will request one flash of the parking lamps. If any door is ajar, no flash will occur, indicating it locked all the doors but one or more doors are ajar. As soon as the last door is closed, the vehicle will provide the one flash of the parking lamps. If 2 presses of the lock button are received within 3 seconds the horn will chirp once, and flash the parking lamps twice to indicate that all the doors are closed and locked. If any door is ajar when the second lock request is received within 3 seconds of the first, the remote control feature will request the horn chirp twice without flashing the parking lamps to indicate it locked all the doors but one or more doors are ajar. When the ignition is in the RUN or START position, no parking lamp flashes or horn chirp confirmations will occur.

Panic Alarm
The panic alarm feature controls activation of the panic alarm providing audible and visual alarms which are evident from the exterior of the vehicle. The panic alarm feature requests that the parking lamps and horn are flashed until deactivation. The flashing of the outputs occurs synchronously. Activation of the panic alarm is accomplished by pressing the PANIC button on an RKE transmitter whenever the key is on the OFF position. At all other times this feature is disabled. Deactivation of an active PANIC alarm is accomplished by: 1) a second press of the PANIC button, 2) the key is switched from the OFF or ACC position or; 3) a period of 2.75 minutes has elapsed since the initial activation.

RKE Keypad
The RKE keypad is available as an option. The RKE keypad is wired directly to the vehicle security module. The RKE keypad is located on the exterior of the driver door and provides a method for the customer to access their vehicle without a key or RKE transmitter. The RKE keypad feature:
- locks all doors and inhibits the door lock control switch UNLOCK capability after 20 seconds (if the inhibit feature is enabled).
- unlocks only the driver door.
- unlocks all doors.
- programs/erases customer key code.
- enables/disables auto-locking.

The RKE keypad feature operates independently of ignition status, vehicle speed, or transmission position. When an RKE keypad button is pressed, the RKE keypad buttons illuminate to provide better visibility. If LOCK ALL DOORS is entered or 5 seconds have elapsed since the last button press, the illumination is turned off.

Each vehicle equipped with an RKE keypad is programmed with a 5-digit entry code. This code is provided to the customer through a wallet card in the Owner Literature package. In addition, this code is available through a diagnostic tool and is also printed on the vehicle security module label. When entering codes each digit must be entered within 5 seconds of the previous button press.

Programming Personal Codes
A unique personal 5-digit code can be programmed by following these steps:
1. Enter the factory set 5-digit code (the RKE keypad will illuminate when pressed).
2. Press 1/2 within 5 seconds of Step 1.
3. Enter the unique 5-digit code.

The personal code does not substitute for the permanent factory set code. Either code can be used to access the vehicle. In addition, if a second personal code is programmed, it will simply overwrite the previous personal code.

Anti-Scan Feature
To provide added security, the RKE keypad is disabled for one minute after 35 button presses without a valid entry code being entered. The RKE keypad will flash during this one-minute mode with all functionality disabled except for 7/8 and 9/0 still being allowed to lock the vehicle.

Anti-Scan will be turned off after any of the following events:
- one minute of RKE keypad inactivity
- the RKE transmitter UNLOCK button is pressed
- the key is turned to the ON position

Unlocking the Doors with the RKE System
To unlock the driver door, enter either the factory set code or the personal code, each digit must be pressed within 5 seconds of the prior digit. The interior lamps will illuminate.

To unlock all doors, enter either the factory set code or the personal code (driver door unlocks) and press the 3/4 control within 5 seconds.

Locking the Doors with the RKE System
It is not necessary to enter the factory set or personal code prior to locking all doors. To lock all doors, press the 7/8 and 9/0 controls at the same time.
