How-to’s of 2006 Corvette M6 BCM fix with GM Tech2

ar model and year: 2006 Corvette M6 Symptom description: The new column lock replacement parts have been installed in my 2005 M6 and now I need to instruct the BCM to ignore any odd codes from the column lock as a part of the fix outlined in the TSB. Tool to use: GM Tech2 TIS2000

Guidance: Will need to pick up a Ac Delco subscription for $40 to start with so you can get access to the new firmware file.

Next, if you don’t have a rs-232 port on your laptop, will need to buy the needed USB cable so you can connect the GM Scanner tech II to your laptop on a USB port.

Now the easy part, Put the tech II into pass through mode, connect it to the car with car in run mode motor off, and bring up TDS on your machine to use SPS. Now using TDS SPS, run through it until you get to the modules mode, and and select Body control module.

In the firmware selection screen utility to disable the steering control lock in calibration, and flash that it.

This will cover you to see what to select the firmware file to flash in.

FYI, it’s a new file and one that will not be in TIS2000 unless you have an active account that can connect to GM to pull the needed updated firmware file that was just released this year. Most don’t, so TDS for $40 for two years it the cheaper option.

A frustration to be solved:

Got the usb to rs232 cable and the $40 subscription but cannot for the life of me get the laptop to connect to the Tech2 and the car. I am getting messages from the website to restart my programming interface and when I log in and try to add the VIN, the website takes me to a bunch of warning messages and unread alerts. Once I get SPS up and try to run the process after selecting the Tech2 pass through mode and checking the connection, I just get error messages. I have gone the rough the connection and login process several times and followed the connection instructions on SPS exactly. I don’t know if I need to enter the VIN someplace but can’t seem to do that. The Tech2 connects to the car fine so it has to be the web, laptop, tech2 connections that is not happening..

Solution:

When you start SPS the first time, you have to set it up correctly. There are a few programs that you needed to download and install, as well as allowing a few sites to get through, then final Java updates that are needed.

After this and you have sps start up, when you get the first pop in SPS , did you install the Tech II J2534 driver or not?

Lastly, with Tech II connected to the machine, go in device manager and make sure that the tech II is showing up in the list as well.

Also to point out, not sure where you bought your Tech II kit from, but should have come with a candi module from the start that should be in play.
