DIY Hyundai WebTech Guide
Doohickie. Let him know if he spelled anything wrong or if you have any suggestions
for this guide.
Introduction to WebTech
The Hyundai Service Technology Website, the key component of which is WebTech, is a link to company
technical data for Hyundai automobiles. To my knowledge, Hyundai is the only automaker
that is so open with their techinical data.
With free registration, there is free access to the site. There are several requirements
to use the site:
If you need the Adobe or Macromedia products, there are links available to download and
install them from inside WebTech (more on that later; look for Site Requirements).
You can navigate WebTech without these programs, but you will not be able to see
all the content, especially diagrams, pictures, etc. WebTech will NOT work with Firefox,
so if that is your browser of choice, sorry.
- Internet Explorer 5.5 or higher
- Windows 98/NT/2000/ME/XP
- Adobe Acrobat Reader
- Adobe SVG Viewer
- Macromedia Flash Player
To register your own username, follow these steps:
- Go to the Hyundai Service
- Select the ink that says, “Click Here to register for an account” (below
the Login button).
- Fill in the requested information on the account creation page. Make sure
you provide a valid email address which your password will be sent to.
- Click on “Create Account”.
- On the page that comes up, click on “Back to login page”.
- Enter the user name you provided in the User Name space and select the link
that says, “Forgot your password?” (Although this may not be necessary, many
people have reported never getting the email with their password until going
through this step, including this author.)
- Save the email with your password. It will be an ugly computer-generated
password that will be impossible to remember. To the best of anyone’s knowledge,
there is no way to change your Hyundai WebTech password.
- Or, if you prefer, just use the username and password from the forum.
Here is a brief site map of the Hyundai Service Technology Website. Upon logging in,
you will be taken to the Welcome Page. There is a column of buttons along the left
that looks like this:
Here is a brief discussion of the links available from this navigation bar. The
information that is most likely to be useful to owners is marked in
- Hyundai logo: Clicking on this or Home anywhere within WebTech
will bring you back to the WebTech Welcome page.
- Service Information: This goes to WebTech,
the online version of the InfoTech service information system used by Hyundai.
It is a treasure trove of technical information. For more detailed directions on
how to navigate the WebTech site to access this information, click here:
Home: Brings you back to the WebTech Welcome page.
My Profile: Displays information about your user profile but you
cannot change anything :- (
Site Requirements: In this area you can
download and install Adobe Acrobat Reader, Adobe SVG Viewer and
Macromedia Flash Player if you don't have them yet.
Contact Us: Goes to a website feedback form.
Classroom Courses: Listing of courses offered by Hyundai to their
service employees. Useless to customers.
Online Courses: Surprisingly, we can audit online courses offered to
Hyundai service employees. There are courses in Automotive Electrical, Noise,
Vibration & Harshness (NVH) and other interesting offerings. Considering the
wheel vibration issues some owners see, the NVH unit is handy; we can see what
Hyundai tells their technicians about the issue.
Course Publications: Course materials available for purchase. I don't
know if only employees can purchase or not; the materials are provided by a
third party company.
Hi-Scan Updates/How to Upgrade/Latest Software: If you happen to have
a Hyundai Scan Tool, you can get the latest software here.
Tools & Equipment
Hyundai SST/New Dealer Kit Order Form/Tool Supplier (SPX): Information
about special tools needed to work on Hyundai cars.
Links Page: No useful links here that are not already on our forum
WebTech Service Information
Upon clicking the Service Information link from the Hyundai Service Tecnology site,
you enter WebTech. There is a message which reads:
Welcome to Webtech
WebTech is the online version of the InfoTech service information system used by Hyundai.
From the top of the screen, please select the publication contents you would like to view.
Next, make your vehicle selection. Note that the more narrowed down your choices are,
the shorter the time it will take to display the contents. Selecting the vehicle model
and year will automatically populate the contents pane with publication contents for
If you would like to conduct a word search on document index information, click Search
in the upper right and the Search pane will appear. Type search terms and select the
publications to search in (defaults to all), then click Search.
Those are the basics of how the site works. When doing a project, however, it can be
difficult to find the exact information desired. Where most consumer oriented service
manuals (Chiltons, Haynes, etc.) group all information on a given topic together, WebTech
organizes it a little differently. There are several types of information, each accessible
by a tab on the page. The tabs contain the following information:
TS. Trouble Shooting Manual: Diagnostic information to help troubleshoot vehicle
- What’s New. A list of recently issued or updated technical documents.
- SHOP. Shop Manuals: Technical information for inspection, removal and replacement
of many parts of the vehicle.
- ETM. Electrical Technical Manual: Includes more than just schematics.
*Connector Map only for later models, starting with 2005 Accent, Elantra, Tiburon,
Tucson, Santa Fe; and 2006 Sonata and Azera. For earlier models, there is no connector
map, and the Circuit Description comes after the Location Indexes.
- Electrical Wiring Diagram.
- Electrical Connector Map. Included in Electrical Wiring Diagram* and shows
pinouts for connectors in that section.
- Circuit Description. Included in Electrical Wiring Diagram* and gives a description
of how the various circuits and the devices attached to them work.
- Location Indexes. Links to photographs of electrical system components
installed on the car. Note that although the photos are to show electrical information,
they are an excellent reference to see what the car looks like under the trim panels.
- Component Location Index. Shows all the electrical devices in the car.
- In-Line Connector Location Index.
- Ground Location Index.
DTC/OBD-II. Diagnostic Trouble Codes for the On-Board Diagnostic II tool:
A guide to decipher each code the OBD-II spits out. If you don't have the tool, many
auto parts stores will check codes for free. From there you can look them up in
this section by number to see what they mean.
TSB. Technical Service Bulletins: Dealer instructions for handling vehicle
issues. If Hyundai discovers a problem that affects many cars, they issue a TSB. Although
you may not get a recall notice for a known problem, if you are aware of the TSB and
your vehicle is under warranty, you can take your car in and direct the dealer to
perform the work per the TSB.
Search & Navigation Tips
I hope you find this information helpful. Hyundai is one of the best automakers out there
as far as sharing information with its owners. It is my hope this guide will help
Hyundai owners make the best use of this information. If you have any comments at all
about this page, please contact me
and let me know if you have any suggestions for this guide.
- Navigation options.
- Contents. Using the Contents option means wading through a few levels of vehicle systems
and components to find the desired information, and sometimes the information isn't
listed where it would seem to belong. The best advice is to invest a little time
to learn how the vehicle systems are organized.
- Search. The other option is to use the Search. The problem with this option is that
one has to know what the item is officially called. Sometimes this is obvious, but
often there are common names that different from the official names in Hyundai's
- Navigation Column. The navigation column on the left side of the page
can be dragged to make it wider or narrower. This can be handy when viewing the manual
page or guide- the smaller the index, the bigger the manual page.
- Print Friendly. In the document pages, there is a Print Friendly link. Selecting this will open
the document in a new window with no navigation bar which is easier to scale.
- Look at all Tabs. When trying to find information, it often pays to look under all the tabs. Even
if you are not concerned with the electrical details of a project, the ETM Location
Indexes include photographs of installed equipment which can reveal details of installation
not readily apparent in the SHOP diagrams.
- Look at All Model Years. If the model and year of your car does not have the desired information, do not give
up. Since most designs are produced for several years, the information may be available
in a different year.
- Look at
Hyundai Parts Online. Use the corporate parts website to figure out how things are
assembled. The parts catalog features lots of exploded-view representations of vehicle
components to show where they go on the car and how they fit to other pieces. This
is helpful to parts managers to make sure the right part is ordered, but is also useful
to the owner when he is working on his car. HPO is also handy for finding which parts are
needed for a job and can help establish whether parts from one platform can be used
- Use Location Indexes to Find Photos. When looking at the Electrical
Wiring Diagrams, ignore designations for Photo numbers (such as "PHOTO 41"). Instead,
look at the name of the component in the diagram and look it up in the Location Indexes.
- Connector Maps. For models that include the Connector Maps, there is a lot of information that
can help in establishing commonality between parts and platforms. For instance,
if two parts use different connectors or pinouts, they are obviouisly not compatible
with each other. If they share these aspects, though, they may be.
- Save for Future Reference. When browsing a document in a frame in or the
main window or in a Print Friendly window, a document can be saved as a Word or
HTML document by keying Cntl-A (or Select All) and Cntl-C (or Copy). Then open up
a new Word document and Cntl-V (or Paste) into the Word document; or select Edit >
Paste Special > HTML Format. Be aware, though, that not all the graphics will seemlessly
paste into the document. If the pictures, figures and/or charts are missing, it may
be necessary to manually go back to the web page, right click on each graphic, return to Word,
click the cursor where the graphic needs to be and select Edit > Paste Special > Device
Independent Bitmap. Doing this will make it possible to review the document in the
future without going to the internet.
- Online Courses. Don't forget about the Online Courses available at the
Hyundai Service Technology Website. While they tend to be general in nature and not
specific to a given model, they may be very useful in learning the right way to service
your Hyundai, and also help you learn to speak the language of the Hyundai Service
Technician when your car does have to go in for service.
- For Instance... Here is an example that puts several of these tips to use: To find the procedure
to change out the Cabin Air Filter of a 2002 Sonata, look in the SHOP manual for the
2004 Sonata, under Heating, Ventilation & Air Conditioning > Air Conditioning
System > A/C Air Filter > Replacement. Notice, here, that searching for Cabin Air
Filter would not lead to this information, but using the Contents tree eventually gets
there. Also notice that the information is not available for the 2002 Sonata but that
the 2004 Sonata is similar.
