Circuit/System Testing



1. Verify the Bluetooth (R) antenna is properly connected to the K73 telematics communication interface control module and is not damaged.



瀚慖f the antenna is disconnected or damaged, repair or replace as necessary.



2. Ignition ON, verify the DTC B2485 is not set.



瀚慖f the DTC is set, replace the Bluetooth (R) antenna. Clear the DTC and cycle the ignition OFF then back ON. If the DTC resets as



current, replace the K73 telematics communication interface control module.



Repair Instructions



Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.



* Wireless Communication Interface Antenna Replacement (See: Accessories and Optional Equipment/Antenna/Service and Repair/Wireless



Communication Interface Antenna Replacement)



* Control Module References (See: Testing and Inspection/Programming and Relearning) for telematics communication interface control



module replacement, setup, and programming



Vehicle Access



DTC B2494 (Manual Liftgate)



Diagnostic Instructions



* Perform the Diagnostic System Check - Vehicle (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System



Check - Vehicle) prior to using this diagnostic procedure.



* Review Strategy Based Diagnosis (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Strategy Based Diagnosis) for an



overview of the diagnostic approach.

Instructions)provides an overview of each diagnostic category.



DTC Descriptor



DTC B2494 00



- Liftgate Handle Switch Circuit



Diagnostic Fault Information



Circuit/System Description



The liftgate release switch is an input to the body control module (BCM). The BCM supplies battery voltage to the signal circuit and when the



release switch is activated the signal circuit voltage goes low. The BCM controls the liftgate release actuator through the liftgate latch release relay.



When the release switch signal is activated, the BCM enables the liftgate latch release relay by applying battery voltage to the liftgate latch release



relay supply circuit and the relay is energized when the BCM grounds the liftgate latch release relay control circuit. When the relay is energized



battery voltage is supplied to the liftgate release actuator through the liftgate release actuator control circuit.



Conditions for Running the DTC



The system voltage is 9-18 V.



Conditions for Setting the DTC



The liftgate release switch signal circuit is active for longer than 10 minutes.



Action Taken When the DTC Sets



The liftgate latch will malfunction.



Conditions for Clearing the DTC



* The DTC will be current for as long as the fault is present.
