How to use GoDiag GT100+ Connect ECM, PCM for Testing or Programming

[@jorgevallegomez9035]

Very good equipment, I am using GoDiag in my garage.

[@AlexAutoFun]

Hi Jorge! yep! same here, it definitely has come in handy!

[@leslie9271]

Thinking about purchasing for mine. Would I be able to know what’s specifically wrong with the computer and replace anything internal? Or is it simply to tell you if it is bad and to just replace?

[@explsvz4170]

Great video. Would be nice if you could show an example of testing the pcm or programming the pcm.

[@AlexAutoFun]

Thanks E! Ah yes the process would be the same as when the PCM is on the car since we can now connect a OBD2 to the PCM and interact with it. Here is a video showing the basic test functions with an OBD scan tool kzbin.info/www/bejne/mYW7c2mOmqymr6M Additionally a more advanced scanner like this one kzbin.info/www/bejne/opbUioGGf5Zpg5Y could be used if you need access to OEM functions Cheers!

Good stuff. I am having a little trouble connecting a 2016 Ram with a GPEC2a ECM but hopefully I'll sort out the right pins and leads to use. But thanks for the info.

[@AlexAutoFun]

You're welcome GroovinJim! ah yes it just takes some patience while figuring out the pin out for each vehicle (if you have the factory service manual it helps tremendously) Cheers!

Great video

Thanks Keen Owl!

[@kambativefemale3083]

Hi and thank you for the video. I’m trying to understand how you knew which OBD wire number to use and when to use the K-line. My wiring diagram shows a CCD BUS(+) and a CCD BUS(-) which I understand to be two wires to connect to all the modules. So which obd wire would I choose for those?

[@AlexAutoFun]

Hi! I would refer to the service manual and wiring schematics, this is the safest way to determine which pins should be connected. Cheers!

[@partoems9376]

Hi, thanks for the video. I got my gt100+. Now the issue is wiring diagrams and interpretation. Can Alientech ECU pinout connections help to connect the ecu properly? Also do share the car schematic video as well. Waiting. Thanks a lot.

[@AlexAutoFun]

You're welcome PartOEMS! I have not familiar with the Alientech ECU system so I can't say if it will help with pinouts. What I use for the pin outs is the service manual as it details each one of the pins on the PCM (which I used for reference for the pinout I showed on this video). Hope this helps, Cheers!

[@adrianrenteriaramos340]

I like the way you explaint,, would you be able to do it with a sensores?

[@AlexAutoFun]

Thanks Adrian! Yes sensors (or sensor simulators) can be connected to this setup to test the PCM. Hope this helps, Cheers!

[@robertfrancisco1193]

how about making a video on basic test functions/ troubleshooting with the BOB thanks

[@AlexAutoFun]

Hi Robert! ah yes the process would be the same as when the PCM is on the car since we can now connect a OBD2 to the PCM and interact with it. Here is the video showing the basic test functions with an OBD scan tool kzbin.info/www/bejne/mYW7c2mOmqymr6M if it helps, Cheers!

[@robertfrancisco1193]

@@AlexAutoFun i guess i was talking about testing in general other than ecu. most of us or i wont mess with pcm plugging in the BOB to DLC and go throw a general troubleshooting test for diagnostic over all health check thanks

[@AlexAutoFun]

@@robertfrancisco1193 Ah I got you, I think you mean how to test individual circuits, that can be done with a voltmeter, some dummy resistances (either some resistors, potentiometer and in some cases the actual sensor itself) I do have a video coming on how to use a multimeter including how to understand different electrical components and their functions, maybe it would make sense to follow that one up with how to use it along with components using the with the breakout box (I would still recommend using the OBD2 scan tool along with the multimeter, since the meter will only give us raw information vs the interpreted data from the PCM to the DLC), good suggestion..

Can this be used with vag key login to find login for module adaptions, abs, steering rack, engine etc ?

[@AlexAutoFun]

Hi Gary! I'm not familiar with the Vag key but if the tool uses a standard OBD2 port, then yes, the ECM can be powered up to access it via the OBD2 port of via the banana jacks if needing to tap into specific lines (some IMMO systems need this step). Here is the full review so you can see how it works kzbin.info/www/bejne/h3LaoayJhLKEi6s Cheers!

[@rockyboss27]

Hi sìr plz help i buy gidiag gt100 pro but i don't no ecu pinout diagram plz tell me i buy wich software or pdf for pinout

[@AlexAutoFun]

Hi Rocky! Correct, it does not come with ECU pin outs (there are too many to be able to include in a single manual. You can get acopy of the service manual for your vehicle from your dealer or you can get one from an online store (some are one time buys and some are subscription based services) Cheers!

[@chanusk7442]

Hello Sir, this kit can used for excavators Ecu

[@AlexAutoFun]

Hi Chanu! I'm not familiar with excavators, but this ECU breakout box works supports 9VDC-24VDC (however the adapter included is 12V) and OBD2 communications protocols (CAN BUS, K Line Pwm, Vpw+, KPW 2000). And here is my full review for the GT100+ if you want to see the rest of it's features kzbin.info/www/bejne/h3LaoayJhLKEi6s Cheers!

[@SS-U23]

Hi, If a car is equipped with immobilizer, how can I power up the ECU with GODIAG on a bench? The other concern is that can I provide a crank signal from a sensor simulator and get ECU outputs like injector driver and ignition trigger? Thank you

[@AlexAutoFun]

Hi! Typically a vehicle with IMMO can be accessed (Key On, Engine Off). The IMMO normally only limits being able to actually turn on the engine. The GT100+ is mean to access the ECM in the Key On, Engine Off state, it's not meant to simulate the vehicle running. However if desired the IMMO function can be accessed with the included jumpers shown on my full review for it kzbin.info/www/bejne/h3LaoayJhLKEi6s or using the GT105 kzbin.info/www/bejne/b6K0gmqoesp7i8U Cheers!

[@SS-U23]

Sounds good! At least we can verify that there's communication with the ECU because sometimes scan tools cannot communicate with the ECUs due to issues with power, ground , network, etc... Thanks again @@AlexAutoFun

[@AlexAutoFun]

Exactly, you're welcome friend!@@SS-U23

[@MrIbrahimeonline]

Hi, i want to connect GoDiag to the instrument on the bench how to know the cable to be connected

[@AlexAutoFun]

Hi Ibrahime! Yes this video shows how to connect an ECM for bench testing (with the pins chosen based on the service manual and wiring schematics for the car being tested). Each car has it's own pin out so some cars will need more or less wires to interface to the PCM (And I do have another video coming in where I cover how to read wiring schematics for those new to them). Cheers!

[@andrewdouglas2609]

Hey I was watching your connection on the video question would those connection be the same for an 06 dodge charger rt seeing the computer are similar if not can you point me in the right direction or which pins should I use, I'm not getting the VPW+ signal on the godiag gt 100 +

[@AlexAutoFun]

Hi Andrew! Ah I would be really careful, while the NGC has been used for a long time and on many vehicles and the pinout may have some similarities I would recommend referring to the Service Manual of the vehicle being tested to confirmed the actual pin out. Hope this helps, Cheers!

[@albertquinto2119]

can i bench test the 24v ecu ??

[@AlexAutoFun]

Hi A! The listing for the GT100+ shows it's rated for 12V-24V And here is the full review for it kzbin.info/www/bejne/h3LaoayJhLKEi6s so you can see the rest of it's features, Cheers!

[@kamilalabd8827]

Please I don’t understand how any why you choose this pins not other pins … please can you explain to us by Video how we can get the pin out

[@AlexAutoFun]

Hi Kamil! As shown on the video I choose those pins based on the service manual wiring schematics for the car. Each car has it's own pin out so some cars will need more or less wires to interface to the PCM (but yes I do have another video coming in where I cover how to read wiring schematics for those new to them).

Hi Otuku! You can see how I use a stadandar OBD2 scanner to connect to the GoDiag as shown on my full review here kzbin.info/www/bejne/h3LaoayJhLKEi6s And here is another video where I show how to use the OBD2 scanner to get live data kzbin.info/www/bejne/mYW7c2mOmqymr6M if you need help with that. Alternatively a multimeter can be used as well, here is my video showing how to use an automotive multimeter kzbin.info/www/bejne/a5PKgYqfgN2meck And finally you can also use a Oscilloscope to get a reading, stay tuned video on how to use one coming up.
