A Very Important Thread UPDATE on Wednesday, July 10th, 2019:

The Very FIRST thing to do when Reading This Thread... is to:

Visit Post #15 where @GENMOTMAN has added in the TECH2 Paths.pdf

THIS DOCUMENT SHOULD BECOME YOUR TECH 2 DIAGNOSTIC BIBLE...

So Download it... Email it to yourself. Keep several Copies of this Incredibly Necessary Diagnostic "FLOW CHART" and maintain it on a Thumb Drive within your "GYMKO" Tech 2 Kit. You will NOT Regret it!

What makes this information so very valuable is that it covers a myriad number of Required Step-By-Steps necessary to Follow when using your "GYMKO" Tech 2 Hand Held Scanner and Diagnosing a Broad Range of Problem Categories encountered with most GM Motor Vehicles and Trucks.


If you have obtained a New “GYMKO” Tech2 Clone Scanner and want to get your feet wet with its various functions... or even for Experienced Users… Here are some Additional TIS2000 “How-Tos” and Instructional Videos that will assist with cutting to the chase scenes when using either your OEM or “GYMKO” Tech2 Scanners or in combination with the Laptop Computers for Specific Tasks:

Caution-> This is the Latest 2017 PCMCIA Tech2Win FREE Software Download<- Caution:

READ EVERYTHING HERE… BEFORE DOING ANYTHING… This software described at the very top section of this Link is UNTESTED and requires following the other links and Instructions to avoid encountering any Security Issues. I would suggest that you obtain an Extra PCMCIA Inexpensive Card available from aliexpress.com Vendors that is pre-programmed with the 33.004 Version of the Software ...and overwrite IT using your TIS2000 Laptop and GM Tech2 Clone with this New Software Version for Testing Purposes ...rather than risk your existing Original PCMCIA Card with the overwrite.

It might prove very useful for many New (and Experienced) “GYMKO” Tech 2 Owners and Operators to have a Ready Source of Tech2 Instructional Videos on how to actually perform certain functions with this Hardware and TIS2000 Laptop Software. And so, I’ll try to populate this Thread with Simple Titles and links to the YouTube Videos that cover these subjects in detail.

I am suggesting that these Videos make more sense if Downloaded and Saved to your Tech2 Multi-Media Folder so that later on… you can safely practice with your New Tech2 and learn and study at your own pace to improve your confidence with the “GYMKO” Tech 2 before you get into any serious PCM Updating and/or New Module Installations. Remember to use the LATEST TIS2000 GM PCMCIA CARD Ver. 33.004 whenever performing any SPS Service Updates:

Note... (With the approval from the Admins and Mods...) Please Do Not Post Any Comments or Anecdotal Responses after viewing the Videos in this Thread. Any Contributions of similar Instructional Videos should be Posted only if they are as Complete and as Accurate as possible with their presentation of Unique Instructions, as many people will be relying upon the Accuracy and Reliability of the Multi-Media Information Posted herein:

In some cases... the Vehicles involved will NOT be GMT360 SUVs and Trucks... but the concepts and procedures will stand out as being the most important aspects in these Videos:

This is a Very Interesting Find concerning the GM OEM Tech 2 Information updated in 2019 that describes the entire Layout and Performance Parameters of the Original GM Tech 2 Handheld Scanners. The data is reduce-able to a Linked PDF...but I was unable to figure out how to Download the Damned Thing. The importance here of course, is being able to see first hand what the OEM Units were designed to do ...and as such, it offers us a Mode of Comparison between the OEM GM Tech 2s...and the "GYMKO" Clone flavors of this Device.

There is also some information nested in the Documentation that covers the Licensing of the GM Software and the fact that when the System Software becomes out-dated...that the Tech 2s will still continue to function... (wouldn't THAT be a Kick in the Teeth if the Tech 2 Clones just stopped working one day because they hit a programmed Time String that triggered a System Failure to occur?) Anyway... FWIW...this data is ordinarily meant strictly for the Original Market for the GM Tech 2s and will make for an interesting Read:

.... Which translates to mean that my latest Thread on having a Strictly Multi-Media has turned out to be a Bad Idea...


The reason I created the OTHER Thread was to Aggregate the Multi-Media portion of the Tech-2 Training Videos for the ease of people who prefer strictly Visual ...rather than Text Learning. This seemed to make perfect sense to me... but apparent that is not the case. So... @Mooseman ... if you deem it necessary to combine these all under the same Thread... I have no problem with that:

This is a VERY Unusual application of using the "GYMKO" Tech 2 Clone on a 2005 Work-Horse Chassis RV sporting the GM Vortec 8.1L Engine and fitted with the Allison Transmission... when other Scanners would NOT show Hidden Trouble Codes or read information on the Transmission. The VOP (Video Original Poster) sounds like he could NOT be any Happier ...if he was TWINS!:



2005WORKHORSE.jpg

In these two Videos... The VOP (Video Original Poster) covers HVAC Testing of his 2005 Cadillac Escalade. Note that the value here is in being able to observe more 'Hands-On' usage that will assist New Tech 2 Owners by watching how this tool gets used under real diagnostic events:



This is DrShock performing an Automated ABS Brake Pressure Bleed using an After-Market Pneumatic Brake Fluid Hand Pump connected to a Master Cylinder Reservoir Cap along with his "GYMKO" Tech 2 Scanner to Activate the ABS Motor Gear and "Exercise" the ABS System to purge any Air Bubbles out of the System:

A Basic Un-Boxing Over-View of a “GYMKO” Tech 2 with Boot Up and Loop Back Test:


...and from the same VOP (Video Original Poster) ...How to Perform the "GYMKO" Tech 2 CANdi Self-Test:


This one shows what happens when the VCI Loop Back Test that FAILS:


THIS Video is Very Interesting as a User maneuvers through solving Serial Communications between the Tech 2 and his Laptop TIS2000 interactions:


This Video comes from the same VOP above and is a perfect example of why "The Squeaky Wheel ... Gets the Grease...". In it, he complains about God-Damned nearly EVERYTHING about this Inexpensive Clone. But.. he also provides some other good insights about what may need to be taken apart and "tidied up".

He also makes mention of the problem @Mooseman has addressed many times about the Tech2 losing power and shutting down under certain conditions. In any case... its value lies in getting yet another opportunity to "look over the shoulder of a Tech 2 User" and add his experiences to your own:


For anyone struggling with running TIS2000 Legacy Software or TIS2WEB on Computers that Do NOT have Native Nine Pin Serial Ports and also being troubled with problematic USB to Serial Port Adapters... This video and the Comments and Links provided by the VOP on his Youtube Channel could be the solution:

For anyone driving the Saab 9-5 and suffering from single wire-resistor based Horn/Steering Wheel/Airbag/Clock Spring Replacement and Repair issues, this intrepid Scandinavian Youtuber, - Trionic Seven - Uses a Tech 2 to work things out over this close to one half hour long Video:


Spending only 5 Minutes in direct conversation with this “Whiner” would make you want to go Hang Yourself in the Garage… as he describes his Tech 2 Clone Purchase while lacing the dialogue with endless complaints about EVERYTHING… and yet, almost within the same breath… he adds in praises for most of the aspects of his Chinese Clone Purchase. In the end he basically says, "My POS Tech 2.... is REALLY NOT a POS...":


Here is a Saab Owner visiting a Friend who owns a Tech 2 to try it out on his vehicle and then explaining all the Hardware and its utility:



Here is a fraction this this Guy's Classroom Tech 2 Study of the Saab Security Issues using a Virtual Windows-GlobalTIS Application. This one may be a bit complimentary to @southsidesmoka ‘s “How to Set up Windows 7,8,8.1,10 Versions with TIS2000” Thread:

In answering a freshly related Tech2 Question covering "How to Use the Tech2 to Diagnose 4WD Trouble Codes"... This Video was available and the VOP (Video Original Poster) provides EXCELLENT Video of the Tech 2 Scanner Screen as he presses the appropriate Function Buttons to navigate over to TCCM and other Transfer Case Encoder CXXX Trouble Codes. So... if you have your own Tech2 and want to poke around and sort out these GM Truck 4WD Issues... THIS is the Video for YOU!


(NO SOUND) Re-Flashing the PCM of a Chevrolet Silverado… observing SPS Laptop PASSTHRU using a "GYMKO" Tech 2 Scanner to OBD2 Port:


This next Video might interest @littleblazer as it covers a problem with a GMC Duramax 6.6L Diesel going into "Limp Mode" and how the VOP uses his Bosch Vetronix Tech 2 following some complex and seldom seen Test Procedures during these Diagnostics:


...that leads over to a Better Hands On Repair repair of this problem, courtesy Eric "Oh" over at South Main Auto. He investigates another related and similar Duramax Problem and manages to give us a closer at the repair while using a different High End Scanner to Perform the Job. Again... this is just one more set of Videos that can Edify Tech 2 Users about some of the other uncommonly accessed features:


...and WOW! Look at what GM Sent to Eric AFTER watching his Last Video... apparently... they DO Pay attention to what the World Thinks about the problems with some of their Vehicles after watching his South Main Auto Channel and responding to his dilemma... This is Interesting as HELL!

How to Use the GM "GYMKO" Tech 2 Scanner to Disable DRL (Daytime Running Lights)

This Linked procedure (with Excellent Tech 2 "Step By Step" Screen Print Imagery is quite straightforward... However, as with all cases of using your Tech 2 Scanner... Certain critical precautions should be followed to Prevent "Bricking" the PCM or other Modules in the process:

(1) This particular activity ACCESSES AND ALTERS THE BCM MODULE FEATURES... so it is very important to ensure that your SUV-TRUCK Battery is Fully Charged.

(2) The 12 VDC POWER SOURCE MUST come from plugging in the Power Connector into the DLC-to-OBD2 Adapter on the Tech 2 DLC System Cable and NOT into the Base of the Tech 2 Scanner.

(3) Have a Completely Decoded and Accurate RPO Listing for your particular Vehicle Printed Out and Handy for when the BCM Access Screen shows the RPO Options that can either be turned On and Off. Select ONLY the one that either Disables or Enables the DRL Feature.

(4) Follow each Step and Do NOT Turn Off The Ignition Key or Power Down the Tech 2 until ALL procedures and steps have been completed.

How to Use the TECH 2 to Re-Program an Updated Transfer Case Motor Module

DTC C0327 TRANSFER CASE ISSUE


From around 9:55 into this Excellent “How R&R & Update via the TSB the TCCM Transfer Case Module Internal Component” Repair Video from RealFixesRealFast, Duane employs a Mobile Re-Flash Service Technician who came to his Auto Repair Shop and used his Tech 2 and Laptop with SPS Programming via the PASS-THRU Communications to re-program the Repaired Transfer Case Updated Module. Just follow along with his explanation and procedures.

I note that @Mooseman could become "The Man In Canada" for such Tech 2 Go To Repairs if he was looking for the chance to travel and still keep his hand in 'The Game' after his Retirement... :>)

Dr. Shock shows us How to Identify The General Motors Vehicle Product Lines and this first Link allows us to Access, Download and Save this useful additional reference material:




http://iconnect-corp.com/specs/vendors/generalmotors/corporate/gmcorp_desadv.pdf






The VOP (Video Original Poster) directly refers to the General Motors Systems Programming Service Guide (...which I was UNABLE to locate ...a Link form Dr. Shock would have been helpful here) during his explanation of the relationships this important identifying information has to the use of the “GYMKO” Tech 2 Scan Tool:
