06 GM Corvette check engine light on

Story goes like this:

I recently took my 06 GM Corvette to our local GM dealership of an oil change. My car has almost 26,000 miles on it, it’s in presteen condition and runs perfect. A week ago the “check engine” light appeared on the dash (the same time the “change oil” display appeared). My assumption was the check engine light was associated with the needed oil change. The service department manager calls and informs me my car needs a ECM ($500). I realize the car is 11 years old, but at 26,000 miles I wouldn’t dream of having to start replacing practically brand new parts! Should I get a second opinion? Is the ECM a known issue with this model? Shouldn’t the car run bad if the ECM needs replaced?

So the second opinion to troubleshoot is to pull the codes with a GM scanner, the popular working one is GM Tech2.

Then I search and choose a web store who I think is reliable: www.fobdii.com, it is around 250USD and it’s an old site because I am considering if I have any question after I ordered they can help me fix it.


I was taking my car to a dealer for an oil change, I would be in way over my head with that level of scanner. I should have had the CEL code read as soon as it came on, not assumed that it was related to the OLM.


Attached one senior user’s review on GM Tech2 I think it is helpful:

I thought it was a worthwhile investment since there are 3 GM cars in the family fleet.

2 days after mine arrived I promptly scanned and cleared the code. My check engine light came on immediately after I detailed my engine compartment to get it ready for a car show. I had the air filter assembly out to clean it and it threw an erroneous code “High Intake Air Temperature” when I started the car. I cleared the code and it hasn’t come back on since.

If you are the first installment on the purchase and saved a trip to the dealer. These new cars and their complex CAN bus computerized systems have been known to have electrical gremlins. I have had 2 instances in the 6 months of ownership where the cruise control quit working. To repair it I had to disconnect the battery, let it sit for a while, hook it up again and it was fixed.

What is the Best Tool to Read and Write BMW CAS4?

Here is some experience of which tool is best for reading and writing BMW CAS4, which may help you to get a safe tool…and know can “xprog safe or xhorse better?”.


If you want a cheap tool for CAS4, get a R270 or R280 programmer. But it’s not the best quality and maybe you have to rework the pcb to work better.

On a side note, Xprog does not want to do the job very well, I cannot recommend it.!


VVDIprog does Cas4 + fine. the only tango adds pcf7939 chips

This is how VVDI prog read/write CAS4 5M48H.

Quick guide:

Open VVDI Prog software, select type, manufacture and model as MC9S12XEP100)

Click “Wiring Diagram”

Maximize wiring diagram: right click and select “zoom window”, then pull down window.

Follow the wiring diagram to connect CAS to the VVDI Programmer.

Start to connect the cable.

The left zone is done, next is to do the right zone.

In this wiring diagram, it only need to remove one 0 ohm resistor to read out data, but one CAS ECU structure is different another one, some needs remove more electronic parts; we will show how to do in the other videos.

Next is to remove this 0 ohm resistor.

Wiring is done, 0 ohm resistor is removed

Plug adapter into VVDI-Prog.

Close wiring diagram.

Select “New” – ” Read”

You see it is reading data very fast.

Reading data successfully, click “Save”

Next is to check data.
Open the data, drag the mouse to check, okay, data is all read out, close it.

How to set up John Deere SA to work with Nexiq clone ?

FYI, John Deere Service Advisor 90% works with Nexiq China clone.

John Deere Service Advisor EDL V2 Electronic Data Link Truck Diagnostic Kit

Electronic Data Link (EDL) is the dealer diagnostic PC-to-vehicle interface compatible with Service ADVISOR software. With Service ADVISOR you can view service manuals, use DTAC (Technical Assistance Center) data, make diagnostics, readings, tests and calibrations, re-program controllers.

Topic 1:  John deere SA possible with Nexiq usb link?


It is possible to install John Deere Service Advisor on your laptop, though the installation is really complicated. If you have a Lenovo Thinkpad laptop, the easiest way is to restore the main partition from the image of my computers’ c: drive. And every time i change my laptop, i just restore it.


Win7 installed and fully updated. It takes hours.

The image will not work on xp, but SA works fine. My suggestion, buy used Lenovo T400 or T500. it’s more or less 250eur in europe. Install windows 7 and then can put my image. Takes 10 minutes and u have SA working.


Topic 2: How to get Nexiq usb link china worked?
I spent a month doing research on this and i managed my Chinese XTruck USB Link to work 90%. The thing is that Nexiq has only 2 channels while EDL has 3. The 3rd one is Powertrain and it is used very seldom. E.g. I reprogrammed all the controllers on 6690 premium except two, but found a way around it opening the pld file with pldeditor and changing Powertrain channel to Vehicle (channel 1). Lots of machines don’t even have a 3rd Powetrain channel. Like all 5R; 6115R, 6125R, 7280R….. From my experience only the older machines have it and still can be programmed most of the time. Programming controllers is easy, but diagnostics is a bit annoying. Every time you establish the connection u have to remove the usb plug and plug it again for the readings to appear. Connection establishment is taking a long long time and you never see the ECU. Only all the other controllers. So all the time something doesn’t work. If you are prepared for this here is what you have to do:

  1. a) Rewire the the cables as shown in the picture in my post here:


I switched places channel 1 with channel 2 (see the pic) with my Chinese version and now it works fine, probably it was possible to do it adjusting the software settings as mentioned above, but i tried a lot, and nothing helped. Now i can connect, tried with 6125R and 5070M. Works fine!!! Except one very important thingy. After i establish the connection, all the reading give the same meaningless number. Then, I discovered accidentally, I pull out the USB cable, get the message “Connection interrupted” I put it back in, get the message “Connection resumed” and wuolla, all the readings show up immediately.


  1. b) You don’t have to change the firmware. Both will work pretty much the same but with different issues.

P.S. For diagnostics only, there is a subprogram of SA that works without any cable rewiring, it doesn’t have a Program Controller option, and you still need to reinsert the usb after connection has been established. You just need to select the right port (which is usually 1939ImplementAutoboud or 1939AppAutoboud depending on the machine) and model. If you have SA, you will find the software at c:\Program Files\Service ADVISOR\xvds\XJDET.exe
Just to let you know, after a year working like that, i bought another EDL (recommended by a folk in the forum, much much much more than the old one)
So much relief
