Passive Entry (if equipped)

NOTE: Some models are not equipped with the passive entry feature, but are equipped with push button start.

The passive entry feature unlocks or locks the doors or opens the liftgate without having to use a mechanical key blade or the RKE transmitter feature.

When the BCM detects a lock or unlock sensor is touched on an exterior door handle, or the liftgate release button is pressed, it activates the low frequency antenna in the corresponding exterior door handle or inside the luggage compartment area. The low frequency antenna sends out a signal to activate the passive key. The passive key then responds by sending a high frequency signal back to the RTM. The RTM interprets the high frequency signal from the passive key and sends the information to the BCM. If the BCM detects a valid programmed passive key, the BCM unlocks the driver door, unlocks or locks all 4 doors, activates the liftgate release switch (if equipped).

Door Passive Entry

With a programmed passive key within 1.5 m (4.92 ft.) outside a door, touch the lock or unlock sensor on the exterior door handle. The doors lock or unlock depending upon which sensor was touched on the handle. The unlock button is located on the inside of the handle and the lock button is located on the outside top face of the handle.

The driver front door passive entry feature either unlocks the driver door (if 2-staged unlock is enabled) or all four doors (if 2-staged unlock is disabled). The passive entry feature always locks all four doors when the lock button is touched.

The passenger door passive entry feature always locks or unlocks all four doors.

Liftgate Passive Entry

With a programmed passive key within 1.5 m (4.92 ft.) outside the liftgate, press the liftgate release button on the rear of the vehicle to release the liftgate latch.

Component Description

Door Lock Control Switches

The door lock control switches are single pole, double throw switches. The DDM and PDM provide the voltage signals to the corresponding door lock control switch for the lock and unlock requests.

When a switch is pressed to lock or unlock, the corresponding input circuit is routed to ground, indicating a request to lock or unlock the doors.

Each door lock control switch has an integral LED to indicate the status of the door locks.

Door Latches

The door latches are sealed units and contain the door lock actuator, lock/unlock feedback switch, and the door ajar switch. The door lock actuators operate in 2 directions, depending on the polarity of the voltage. The door latches can be lubricated, if needed. Refer to: Door Latch Lubrication .

Liftgate Release Switch

The exterior liftgate release switch is a momentary contact switch that supplies a ground signal to the BCM. When the exterior liftgate release switch is pressed, the signal is routed to ground indicating a request to the BCM to release the liftgate latch. The release switch only operates when the doors are unlocked electronically or within 45 seconds of an initial press of the liftgate release button on a RKE transmitter.

Liftgate Latch

The liftgate latch contains the release actuator and the ajar switch. The BJB provides voltage to the actuator to unlatch the liftgate from the striker.

IKT

The IKT incorporates both the PATS and the RKE transmitter functions in a single device.

During key programming procedures, the PATS and RKE transmitter of an IKT are both programmed into the BCM.

DDM or PDM

The DDM and PDM control the operation of the power door locks, power windows, and the power mirrors in the front doors. They communicate with each other and the BCM over the MS-CAN. They also send commands and receive feedback from the DRDM and PRDM over a LIN for each module.

The DDM and PDM do not require PMI when replaced.

Passive Key

The passive key incorporates both the PATS and RKE transmitter functions in a single device.

During key programming procedures, the PATS and RKE transmitter Identification (ID) of a passive key are both programmed. A maximum of 4 passive keys can be programmed.

The passive key also contains a removable key blade that unlocks the driver door in the event of an electrical failure (such as a drained battery). The passive key requires 2 batteries. They should always be replaced as a set. For battery replacement instructions, refer to the Owner's Manual.

To start the vehicle in the event of a passive key battery failure, place the passive key in the backup starting location. Refer to: Passive Anti-Theft System (PATS) - System Operation and Component Description . .

Exterior Door Handles

The exterior front door handles contain a keyless entry antenna and capacitive touch sensor(s). The antennas and lock/unlock sensors are wired to the BCM. When activated, the antenna transmits a low frequency signal to activate a passive key.

Keyless Entry Rear Antenna

The keyless entry rear antenna is wired to the BCM. When activated, it transmits a low frequency signal to activate a passive key.

RTM

The RTM communicates all RKE and passive key information to the BCM over a LIN-based circuit whether or not the CAN is active. The RTM is a receiving antenna that receives the high frequency signals from the passive keys.

The RTM requires PMI when replaced.

BCM

The BCM is the master module in control of the power door lock system. It is responsible for locking/unlocking the doors. The BCM receives inputs for the door lock control switches, keys and RKE commands over the CAN and LIN-based circuits.

The BCM requires PMI when replaced.
