Example TechHelp Request

The example TechHelp request below highlights not only the original request, which included some waveforms posted by the member for extra detail on his issue, but also the related documents & media found on iATN, and our sister company Identifix's Direct-Hit product. Not shown in the screenshot are the replies received by the member on their help request, and the fix they posted describing how they solved the issue with the vehicle.


Using TechHelp

Although iATN TechHelp originally started back in 1995 as an email-only service, most members use TechHelp today via our website, where they have the ability to filter their view of TechHelp down to requests on very specific makes, models, and other keywords. In addition to the help requests, every member is able to read the final "fix" posted by the author. Premium (paid) members, as well as basic (free) members that regularly offer help to other members, are able to view all of the replies received on each TechHelp request. All of this information is searchable in the iATN Knowledge Base.

Many members use TechHelp not only to help others, but also to keep an eye on the interesting fixes that are posted each day. Subscribing to TechHelp by email is a great way to keep up-to-date on the latest issues facing your favorite carline.

TechHelp by Email

In addition to reading TechHelp via the web, you can subscribe to it via email. Once you join the network, you may begin receiving some TechHelp email help requests from other members, either in summary format (sent nightly), or via individual email requests. You may switch formats, choose a different email volume level (choices range from receiving 0 to 70 help requests per day), and choice of topics. TechHelp email is currently split up into 5 major topics (Asian, Chrysler, European, Ford, and GM), and 10 sub-topics (Body, Brakes, Chassis, Driveability, Electrical, Engine, HVAC, Misc., PowerTrain, and Transmission issues), providing 50 combinations for you to choose from. You can mix and match which topics you receive to focus on your specialties.

Note: To keep the quality of TechHelp requests at a high level, members are expected to offer help prior to asking for help, and members are limited in the number of help requests they can send each month.
