Circuit/System Description
The keyless entry control module provides a 12 V signal to the driver door open switch signal circuit. The driver window motor provides a 12 V signal to the driver door ajar switch signal circuit. The door open switches and the door ajar switches are integral to the driver door latch assembly.
The door open switch and the door ajar switch contacts will be open with the door is fully closed, the door switches within the door latch are designed so that the when the door is ajar, the contact in the door ajar switch closes, the voltage is pulled low and the window motor will then send a serial data message to the body control module indicating that the door is ajar. When the door is opened further, the contact in the door open switch will then close providing a ground for the door open signal circuit, the keyless entry control module will then detect that the door is open.
Conditions for Running the DTC Battery voltage is between 9 - 16 V. Conditions for Setting the DTC
The keyless entry control module detects the driver door open switch is Active while receiving a serial data message from the body control module that the driver door ajar switch is Inactive.
The condition must be present for greater than 2 seconds
Action Taken When the DTC Sets
The keyless entry control module will not notify the driver if a transmitter remains in the vehicle after exiting
Conditions for Clearing the DTC
The DTC will be current for as long as the fault is present.
When the keyless entry control module receives a serial data message from the body control module that the door is ajar before the keyless entry control module detects the door open switch is active, then the DTC will be a history DTC.
A history DTC will clear after 50 ignition cycles.

Circuit/System Description
The hybrid/EV powertrain control module 2 monitors the voltage values of the fuel fill door open request wake- up signal circuit and the fuel door request signal circuit. When the refuel request switch is pressed, the two switch contacts close. This provide B+ to the wake-up circuit input of the hybrid/EV powertrain control module 2 and lowers the voltage on the fuel door request signal circuit input to the hybrid/EV powertrain control module 2. The hybrid/EV powertrain control module 2 detects the voltage on the signal circuits and commands the fuel system to vent and sends a serial data message to the driver information center to display the Wait to Refuel message. The hybrid/EV powertrain control module 2 then energizes the fuel door lock/unlock actuator to unlock the fuel door.

Driver Door Ajar
The driver window motor provides a 12V signal to the driver door ajar switch signal circuit. The driver door ajar switch is integral to the driver door latch assembly. When the driver door is opened, the normally open door ajar switch closes. With the door ajar switch closed, ground is provided to the door ajar switch signal circuit and the voltage within the signal circuit drops. The driver window motor will detect the voltage drop and will send a serial data message to the body control module which will then send a message to the instrument panel cluster to command the door ajar message
Passenger Door Ajar
The passenger window switches each provide a 12 V signal to their respective door ajar switch signal circuits. The door ajar switches are integral to each door latch assembly. When a door is opened, the normally open door ajar switch closes. With the door ajar switch closed, ground is provided to the door ajar switch signal circuit and the voltage within the signal circuit drops. The window switches will detect the voltage drop and will send a serial data message to the body control module which will then send a message to the instrument panel cluster to command the door ajar message.
FUEL FILL DOOR DESCRIPTION AND OPERATION
Refueling System Components
The refueling system consists of the following components:
Refuel request switch
Fuel door position sensor
Fuel door latch
Hybrid powertrain control module 2
Fig. 96: Refueling System Block Diagram Courtesy of GENERAL MOTORS COMPANY
Refueling System Overview
To effectively manage evaporative fuel emissions, hybrid vehicles with extended electrical range capability must be equipped with a "pressurized" fuel system that can be sealed from atmosphere when the internal combustion engine is not operating.
When the fuel system is sealed, the internal pressure will vary with changes in temperature, such as the natural variation in ambient temperature that occurs throughout the day. To maintain evaporative emissions compliance, vehicle refueling can only be permitted once the fuel system has been adequately vented to atmosphere through the carbon canister. The Refueling Management feature described in this document provides the necessary means to regulate customer access to the fuel cap and manage venting of the fuel system in order to facilitate vehicle refueling without compromising evaporative emissions compliance.
Refueling System Operation
The hybrid/EV powertrain control module 2 monitors the voltage values of the fuel fill door open request wake- up signal circuit and the fuel door request signal circuit. When the refuel request switch is pressed, the two switch contacts close. This provides B+ to the wake-up circuit input and changes the voltage level of the fuel door request signal as it passes through a single resistor instead of 2 resistors. The hybrid/EV powertrain control module 2 will detect the 12 volts on the wake-up circuit and the voltage change on the fuel door request circuit, it will then command the fuel system to vent and sends a serial data message to the driver information center to display the Wait to Refuel message. The hybrid/EV powertrain control module 2 then energizes the fuel door lock/unlock actuator to unlock the fuel door.
After the system has been vented, the hybrid powertrain control module 2 will send a command to unlock the fuel filler door and will send a serial data message to the driver information center to display the Ready To Refuel message. After the vehicle has been refueled, the hybrid powertrain control module 2 will send a serial data message to the driver information center to display the Close Fuel Door message until the fuel filler door is closed. The hybrid powertrain control module 2 will then command the fuel filler door to lock 5 seconds after the fuel filler door is closed or the vehicle speed exceeds 40 km/h (25 mph).
LIFTGATE AJAR INDICATOR DESCRIPTION AND OPERATION
Hatch Open Indicator
The body control module (BCM) monitors the voltage level of the rear hatch ajar signal circuit which is normally at the system voltage when the hatch is closed. When the hatch is ajar or open, a switch within the rear hatch latch closes providing a path to ground for the hatch ajar signal circuit. The voltage within the signal circuit will then drop to 0 volts, the BCM will then detect the voltage drop and will send a serial data message to the instrument panel cluster (IPC). The IPC will then display an icon of the vehicle with the hatch open.

Door Lock and Unlock Operation
When the driver or passenger door lock switch is activated in the lock or unlock position, the BCM will receive a ground signal on either the door lock switch lock or unlock signal circuits.
The BCM, upon receipt of a lock switch lock or unlock signal, will supply battery voltage to the door lock actuator lock or unlock control circuits. Since the opposite side of the lock actuator is connected to ground through the other lock actuator control circuit, the doors will then lock or unlock as commanded.
The following three circuits are used to operate the lock:
Driver door unlock
Passenger door unlock
All door lock
The driver door lock actuator is isolated so it can be unlocked by itself using the keyless entry transmitter.
Key Cylinder Switch
The driver window switch monitors the voltage level of the driver door lock motor status signal circuit. When the key is inserted into the driver door key cylinder and turned to the Lock position, a switch within the driver door latch closes causing the voltage to drop within the driver door lock motor status signal circuit. The driver window switch will detect the drop in voltage and will send a serial data message to the BCM commanding all the doors to Lock.
The driver key cylinder switch is used by the customer for programming the keyless entry transmitters, The driver window/outside rearview mirror switch monitors the voltage level of the key switch unlock signal circuit and when it detects a reprogramming request, it will send a serial data message to the body control module.
Passive Door Lock/Unlock Operation
The exterior door handle switch signal circuits provide inputs to the keyless entry control module when the exterior door handle switches are activated. These inputs allow the keyless entry control module to detect a door lock or a door unlock request. The keyless entry control module provides a 12 V signal to each exterior door handle switch via the door handle switch signal circuits. When a door handle switch is pressed, the switch closes and the voltage signal within the signal circuit is pulled to ground. The keyless entry control module will detect the voltage drop and a low frequency antenna will transmit a challenge to the keyless entry transmitter. If the challenge is met, the keyless entry transmitter will respond and the keyless entry control module will send a serial data message to the body control module to command the door(s) to be locked or unlocked

Rear Hatch Release Operation
The rear hatch can be released by placing the transaxle in park, unlocking all the doors and then pressing the touchpad located at the rear of the vehicle above the license plate.
Pressing the touchpad closes a contact providing a ground for the rear closure handle switch open signal circuit. The body control module (BCM) will detect the voltage drop and will pulse 12 V to one side of the relay coil and provide a ground for the other side of the relay coil, this will briefly energize the liftgate relay closing the switch contacts and provide B+ voltage to the liftgate latch. When the doors are locked, the BCM will disable the rear hatch release system by ignoring the liftgate release switch input command and not providing 12 V for the liftgate relay.
