96 LT4 Corvette PCM Reprogramming by GM tech2 Clone

I purchased a 1996 PCM that was used for short money, my goal was to keep it as a spare for my ’96 LT4 Vette since parts are getting harder to come by.
I removed my PCM and installed this used PCM. I took out my GM Tech 2 Clone, opened my Windows XP Netbook that I had previously installed the TIS 2000 software (this software disk came with the Tech 2 Clone). I opened the TIS 2000 application and went to the “Service Program Application” and followed the steps to “Reprogram ECU”.
Now this used PCM obviously had a different VIN. So during the program when it prompted me to see if the VIN was correct I deleted the old VIN and entered in my cars VIN.
Then I uploaded the program for my VIN into the TECH2 Clone per the prompts, disconnected the Tech 2 Clone from my Netbook and connected my Tech 2 Clone to my OBDII port. I turned the ignition ON without starting the car and selected “Service Programming System” followed the prompts and watched the TECH 2 Clone load my VIN programming for my car.
It worked great, in fact I bought a second 1996 PCM for $150.00 and performed the same procedure and that one worked just as well!
After I used my JET DST to upload my Tune for my engine into the PCMs. The Tech II will obviously only install the factory calibrations. Now I have two spares in case my original fails.
Hope this information is helpful.

TIS2000 Application

Here is where you select Reprogram ECU.

These are the prompts for the Tech 2 setup.

First I only have a 1996 with the OBD II, this is all I could experiment with so I can’t check other years.
I think it can also work on the 94, 95 model years as well, but I could be wrong.
The TIS 2000 software comes with the Tech 2 scanner.

2005 GMC Canyon Crankshaft Position Variation Learn by Tech2

All right, today we’re going to be going through a crankshaft position relearn sequence on a Chevy Colorado or a GMC Canyon. My trucks of 2005 GMC Canyon with 3.5 liter, so the first thing we’re going to do today is to have our GM Tech 2 scan tool to setup here, we’re going to plug it into the DC port down here and we’re going to have the obd2 port hooked up down here. Once we have that all hooked up, first thing we’re gonna do is we wanna start our truck and you want to have it warmed up. You can see I’m about probably at 160 right now I think the bare minimum is about 155, so I’m just above the line of what we need to be.

So we’re going to start it and then once we do that we will hit the power button down in the GM Tech2 scanner. It will run through its initialization sequence here.

Go to “Diagnostics”.

Select my year “2005”.

Select “LD Trk, MPV, Incomplete”.

Enter “GMC Truck”.

And the product line code for our trucks is a S. So if you have a Chevy Colorados can be the same thing, it’s going to be Chevy truck and then S.

Canyon.

Going to “Powertrain”.

3.5L L5 L52.

Speed automatic.

Special functions (We wanna go).

Crankshaft Pos. Variation Learn.

Continue.

Continue.

Make sure your parking brake set, it says “Do not apply brake pedal”. We’re going to click “Enter”. It says apply and hold brake pedal so I’m going to apply the brake pedal down there, turn your AC off and vehicle must remain in park or Neutral. Press Enter to continue.

It says “Accelerate to WOT. Release when fuel cutoff occurs.

And try to get both screens here at the same time. You see it already shut me down.

Test in progress.

Learn status: learned this ignition.

Perfect, it’s exactly what we want.

Press “Exit”.

We wanna go “Diagnostic trouble codes (DTC).

DTC information.

DTC Info.

No diagnostic trouble codes.

Back to “Diagnostic test status”.

Clear DTC information.

Yes to continue.

Go back to “DTC info” and no diagnostic trouble codes.

Conclusion:

You just fix the problem, you’re done.

And that’s how you use GM Tech2 do a crankshaft position relearn on a 2004 – 2012 Chevy Colorado /Canyon.

Thanks .
