Hyundai’s New Global Diagnostic System (GDS)
Hyundai Motor Corporation and Hyundai Motor America are developing a powerful new diagnostic tool.
The Global Diagnostic System or “GDS”, for short, offers several new features. The tool, referred to as the “Information Terminal” is housed in Panasonic’s Toughbook™ laptop and allows diagnosis via wireless communication. When configured properly, the wireless function lets those in a wireless dealership environment to access updates or review the parts dialogue without all the wired connections.
The GDS is equipped with touch screen technology that simplifies your communication with the unit.
The screen can be swiveled and locked into a flat exposed position so that the tool can be handled in a

We developed the new tool with the intent of systemizing the diagnostic process. The following stages make up the process:
• Preparation stage: Gathers information about the vehicle and operating conditions for reporting
• Diagnosis stage: Data and DTC analysis functions
• Vehicle S/W Management stage: All ECU related reprogramming or option settings
• Repair stage: Verifies the repair and offers link to parts information
Consider theses stages when approaching diagnosis with the GDS.
Compared to existing scan tools, GDS offers the followingdistinctive features:
• Coupling between information and diagnosis-
The GDS Information Terminal is a computerized system. It is possible to store large amounts of information. Furthermore, it can show the diagnosis results and related information on one screen, in
contrast to existing scanners’ limitations in output due to their limited screen size.
• Quick Support through internet updates-
If new data is introduced or if an error has been generated in the GDS System, data update or system fixes can be made through a real time internet update. Update availability and frequency are increased
through the direct internet interface.
• CAN communication support –
No need for an additional adaptor, because CAN communications protocol
• GDS supports powerful flight recording functions.
• Wireless network support between Vehicle Communication Interface (VCI) and Information Terminal creates greater unit mobility. Multiple users can use the tool without relocating the terminal.
The welcome screen is shown in Figure 1. From here you can choose functions in Preparation, Diagnosis, Vehicle Software Management or Repair. Preparation includes defining the vehicle and parameters being diagnosed. Hot Fix is a new function that searches and displays items from the Hyundai Technical Library that apply to the vehicle, symptom or Diagnostic Trouble Code.
The Diagnosis mode is very powerful and designed with you in mind. We will look more specifically at a few diagnostic functions in this article. Vehicle Software Management Mode facilitates reflashes, VIN rewriting required on some control modules and vehicle software upgrades. The repair mode taps into the Hyundai service knowledge base offering guidance on replacement procedures, part information and circuitry.
To begin a diagnostic session, you can either enter the VIN for the vehicle; or you can select the parameters and systems to be diagnosed in the Preparation mode. Next a vehicle system to be evaluated must be selected. Remember, the tool has a touch screen so selection is easy with the supplied stylus.
Note: Do not use a ball point or other pen on the touch screen. Any stylus made for touch screen activity will work.
Setting and running “Fault Code Searching” function in the “Vehicle Selection” allows users to continue workflow on the primary system (denoted by a check mark on the vehicle selection process) while the GDS searches in the background for DTCs in all selected systems.
The progress status for the Fault Code Searching will be displayed on the top of the “Fault Code Searching” icon, which is located on the lower section of the GDS screen.
First, establish communication with the vehicle. You will need to plug the communication VCI (shown in Figure 2) into the communication port in the vehicle.
To turn on the VCI module, depress the main power switch after connecting the main DLC cable from the vehicle to the VCI module.
Note: If the vehicle DLC diagnosis connector does not use a 16-pin connector, or if battery power cannot be supplied to the VCI module, the cigar power cable must be connected to supply battery power to the VCI module with the vehicle’s ignition switch in the ACC position.
The VCI will run through a test sequence and when it is ready, green lights will be displayed for “PC Comm” and “Veh. Comm” on the unit.
When using a USB connection, the “PC Comm” light will be red.
Note: When the unit is engaged in Flight Recording, its light will appear red.
If communication between the GDS and the vehicle is interrupted, hold down the power button for five seconds.
After you have selected the vehicle information or VIN enter “GO” on the touch screen. This will alert the GDS which vehicle it will be diagnosing. You can also select symptoms from a drop down box or add comments for later review.
Select the Diagnosis mode from the welcome screen. In this mode you can select the various components requiring diagnosis to gather Current Data or Flight Recording. The GDS will return values in real time for Current Data.
In the Current Data mode, you can record and display graphs for up to six inputs simultaneously via the Basic Inspection function. The data can then be analyzed. Just click the box next to the appropriate sensors.
The GDS can return graphs, component location and descriptions, component specifications, circuit Information.
In the Flight Record mode, data from the previous ten minutes is recorded when the trigger is activated.
This becomes helpful for intermittent problems. A condition experienced can be recorded after the fact if you are still within the ten-minute timeframe.
DTC Analysis is a function that runs DTC diagnosis for control modules in a vehicle, and supports specific repair procedures for each DTC. Results appear when DTC diagnosis proceeds through the communication between a VCI and a vehicle control module. DTC list will be shown in the upper section and “Freeze Frame” will be shown in the lower section of the page if the control module in question supports the Freeze Frame function.
If there is no DTC for corresponding control module by DTC diagnosis, message “No Error Code” will appear. If the DTC is found, DTC will be listed on the screen. DTC codes are listed in the first column. DTC name descriptions are listed in the second column. The DTC state (History or Pending) is listed in the third column (State section).
DTC diagnosis updates itself automatically every 25-seconds. It can also be updated manually by selecting “DTC Analysis” on the screen menu at any time.
DTC saved in the control module can be erased after the printout of DTC code followed by the DTC analysis function process.
We have just highlighted a few of the powerful features coming with Hyundai’s new GDS diagnostic tool.
With so much information at your finger tips, thorough diagnosis and repair can be achieved much more efficiently.
Its wireless capability improves mobility and simplifies upgrades. This breakthrough system can
guide your diagnostic procedures and draws on Hyundai’s full service library for tackling the conditions discovered with the tool. Look for future articles walking you through the steps for maximizing the power of GDS.
