Garage Door Opener Connector Parts Information

Garage Door Opener Connector Terminal Identification

Begin the system diagnosis with Diagnostic System Check - Vehicle . The Diagnostic System Check will provide the following information

1. The identification of the control modules which command the system
2. The ability of the control modules to communicate through the serial data circuit
3. The identification of any stored diagnostic trouble codes (DTCs) and their status

The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.

Circuit/System Description

The garage door opener (GDO) is a transmitter operating between 288 and 399 MHz. The GDO has 3 buttons that may be programmed for individual transmitter/receiver combinations to control up to 3 GDOs, security gates, and lighting systems. Each button represents a transmitter code section of the transmitter, which operates separately from any other button, and may be considered a separate transmitter. Battery voltage is provided to the GDO from the PCM fuse in the underhood fuse block.

The keyless entry system is a vehicle entry device. The keyless entry will unlock/unlatch the vehicle doors or open the rear gate when a corresponding button on the key fob is pressed. This is accomplished by the key fob sending a radio frequency to the liftgate module (LGM). The signal is received by the LGM via an internal antenna located within the LGM. The LGM interprets the signal and activates the requested function via a message over the class 2 serial data line. A low transmitter battery or radio frequency (RF) interference from aftermarket devices such as 2-way radios, power inverters, cellular phone chargers, computers, etc. may cause a system malfunction. High RF traffic areas, such as gas stations which use pay-at-the-pump RF transponders, may also cause interference that could lead to a malfunction.

Garage Door Opener Description and Operation

The garage door opener (GDO) is located in the overhead console or drivers side sunshade. If battery voltage is lost due to a condition such as a dead battery, the GDO unit relies on the non-serviceable internal power backup supply. The unit is programmed using the customer's hand-held transmitters for the garage doors, electric entrance gates, or lighting and security systems.

The GDO is rolling code capable. Rolling code is a system that allows the code that the customers receiver receives from the GDO to change every time the GDO is used within operating range of the receiver. Rolling code programming requires the customer to push a learn/program button on the GDO receiver at their home. This button is usually located on the receiver unit under a cover (light cover) on one end of the unit. The customer must follow the GDO manufacturers instructions to program/learn the receiver to accept the HomeLink as an authorized opener for their unit. When the receiver and the GDO are initially programmed together, a code is established and a new code is created for every new transmission. The software in the receiver recognizes the GDO and accepts the new code.

The GDO is compatible with most, but not all types and brands of transmitters. If a problem should occur with a compatibility conflict with a transmitter, call HomeLink™ at 1-800-355-3515.

The GDO is a transmitter operating between 288-399 MHz. The power and range of the transmitter is limited to comply with laws governing the generation of radio frequency interference (RFI). The transmitter is programmed by the user to accept the signal generated by the user's transmitters. Refer to Control Module References for replacement, setup, and programming.

The GDO has 3 buttons that may be programmed for individual transmitter/receiver combinations to control up to 3 GDOs, security gates, and lighting systems. Each button represents a transmitter code section of the transmitter, which operates separately from any other button, and may be considered a separate transmitter. Operation consists of simply pressing a button to activate the corresponding transmitter.

Keyless Entry System Description and Operation

The keyless entry system is a supplementary vehicle entry device. Radio frequencies or discharged batteries may disable the system.

Keyless entry allows you to operate the following components

1. The door locks
2. The rear compartment lid release
3. The illuminated entry lamps
4. The panic alarm/instant alarm

The keyless entry system has the following main components

1. The transmitters
2. The endgate module (EGM) (XUV only)
3. The liftgate module (LGM) (Except XUV)

When you press a button on a transmitter, the transmitter sends a signal to the liftgate module. The module interprets the signal and activates the requested function via a class 2 message over the serial data line.

Unlock All Doors - Second Operation

Momentarily press the UNLOCK button a second time (within 2 seconds of the first press) in order to perform the following functions

1. Unlock the remaining doors.
2. Illuminate the interior lamps for a predetermined amount of time or until the ignition is turned to the RUN position with a valid key.
3. Flash the exterior lights, if selected ON in personalization.
4. Chirp the horn, if selected ON in personalization.
5. Recall the memory seat and memory mirror positions for that driver.
