AIRBAG CONTROL UNIT UPDATE SERVICE CAMPAIGN T79

SERVICE CAMPAIGN BULLETIN

REVISION HISTORY

DESCRIPTION

This bulletin provides a procedure for using the GDS Diagnostic Tool to update the 2009 Genesis Airbag Control Unit (ACU).

IMPORTANT NOTES: 

This TSB provides reprogramming instructions for GDS only. You may have to perform an initial internet update of GDS to receive the latest software version 1.5A. 

If the vehicle has not been driven recently and was in storage, first start and run the engine for several minutes to ensure it has a reasonably charged battery before conducting the reprogramming. A low vehicle battery charge can prevent reprogramming. 

VEHICLES AFFECTED

Model: 2009 Genesis (BH) vehicles.

Applicable vehicle production date range: From April 25, 2008 to November 18, 2008

GDS ECU SOFTWARE REPROGRAMMING PROCEDURE

Important Cautions for Reprogramming:

• Reprogramming by GDS can only be performed by using the USB cable between a laptop and the VCI; wireless cannot be used for reprogramming.
• Make sure the GDS laptop battery indicator at the bottom right of the screen indicates at least 25% battery charge remaining to be able to complete reprogramming; if not, charge the laptop or keep the AC adaptor connected while reprogramming.
• Perform reprogramming with the ignition key in the ON position.
• Turn off all lights (do not leave headlight switch in auto mode) and all accessories (including heater/air conditioner/blower, radio, heated seat, rear defroster, etc.) to make certain the battery will not be discharged during reprogramming.
• Be careful not to disconnect any cables connected to the vehicle during reprogramming.
• Do not start the engine during reprogramming.
• Do not turn the ignition switch OFF during reprogramming.

OPERATION OF THE ENGINE START/STOP IGNITION BUTTON

1. To get to the ACC position from the OFF position, press the Start/Stop button once when vehicle is in PARK, without depressing the brake pedal.
2. To get to the ON position from the OFF position, press the Start/Stop button two times when the vehicle is in PARK, without depressing the brake pedal.
3. To turn off the ignition power, press the Start/Stop button one time without depressing the brake pedal while vehicle is in PARK. If the button is depressed with the shift lever out of PARK, the ignition will not power off.
   NOTE: If the Start/Stop button is pressed while the brake pedal is depressed and the vehicle is in PARK, the engine will start.

1. Connect the GDS VCI module to the vehicle's DLC connector and the USB cable between the VCI and GDS laptop's USB port.
2. Without depressing the brake pedal, push the Start/Stop button two times to turn on the vehicle ignition. Make sure the green power LED is lit on the VCI; if it is not press on the power button of the VCI. Within a few seconds, the GDS screen should indicate VCI:USB On  in bright blue to the left of the VIN button on the screen.
   NOTE: You must have an internet connection to GDS to be able to receive any updated data; the bright blue "InternetOn" should illuminate to the left of the VIN button.
   NOTE: If a GDS internet update is available, it could take up to several minutes to download and complete the update.
3. Make sure the GDS has the latest data by pressing the bottom right Internet Update  button on the GDS screen. You will get a confirmation on the GDS screen if it is already updated (see next page); otherwise the Download Start  button will be viewable and should be pressed to update the GDS.
4. Press the VIN  button at the top of the screen to launch the GDS VIN search screen.
