Approach Detection
The approach detection feature is used to passively activate the illuminated entry feature while approaching the vehicle and will activate the power running boards (if equipped). For power running board information, REFER to: Power Running Board (PRB) - System Operation and Component Description .
To set the vehicle for approach detection, turn the ignition off, exit the vehicle, make sure the liftgate and all the doors are closed and locked. All valid programmed passive keys need to be outside of the area of detection (more than 10 feet) longer than 60 seconds for the BCM to activate the approach detection feature.
When the approach detection feature is active, the BCM uses the passive entry antennas (located in the door handles and at the rear of the vehicle) to detect a valid programmed passive key when approaching within 2.7 m (8.5 ft) of the vehicle. If the BCM detects a valid programmed passive key, it activates the illuminated entry feature and will activate the power running boards (if equipped). For power running board information, Refer to: Power Running Board (PRB) - System Operation and Component Description .
The approach detection feature is not active/does not activate when:
- A passive key is detected inside the vehicle.
- A passive key is detected in close range of the vehicle for more than 2 minutes.
- The panic/perimeter alarm is triggered.
- The vehicle has not been started for more than 5 days.
- The vehicle battery has a low state of charge.
The approach detection feature can be enabled/disabled through the message center.
