2014 Chevrolet Cruze Eco 1.4L (B LUV) 6-spd (6T40)
Crank / No Start

I got called out to check out a 2014 Cruze. It was a theft recovery. The shop had replaced the lock cylinder. They provided a new key. I swapped the blade from the donor key to the new one. I had tried on a previous trip to program used donor key to this car and failed. With the new dealer key, I expected no issues. I first tried the im608 and failed. I then attempted with SPS2 and got a strange error that the BCM was not recognized. One of the suggested steps was to re-program the BCM. I started the process and could see one of the calibrations was not recognized. There were quite a few updates listed so I went ahead and programmed to the latest and greatest. Another 12 minute cycle and I was able to complete the learning process. Modern SPS2. Gotta Love it.

Almost every time I program a later model GM, I see whole bunches of not recognized calibrations…

This is the method GM is using to push out the “cheater” programming solutions. By making older calibration levels “unrecognized”, programming methods that depend on a localized database cannot get a programming lock on that memory slot, effectively making it unprogrammable. This is starting to show up on the much older stuff - any TIS2000 compatible models that got “touched” by SPS at some…

Jeff, it might be possible that GM is thinking this way but I would think they have bigger fish to fry. Its confusing for sure because despite all the unrecognized calibrations (using new modules) its never kicks out for that. Can you explain what is "cheating" about using a purchased, non-expiring, TIS2000 subscription? The EULA says its OK. Last week we had a job on a 2007 Grand Prix where…

“Cheating” in this context means “not providing a continuing revenue stream to the OE”. More than half the work I do is “cheating” in this respect. It means to “make improvisational adjustments to the procedure, process or method that, while imperfect or somewhat less than standard, yield an acceptable result and completion of the task at hand.” Its an old sailing term - ie “cheating into the…

What is SPS/SPS2?

SPS and SPS2 (Service Programming System) are the programs used by GM to program their modules through a sign up and fee via the ACdelco TDS website.

It wouldn't surprise me and sounds a bit like they tried to replace the lock cylinder with a matching bcm from another car to try and get around paying someone to make and program a new key.

BCM VIN matched the vehicle. Unlikely that BCM had been swapped.

If by some miracle the BCM had the latest files already, would you not be able to program/update it to accomplish your goal of learning the key?

I don't think I would have had the error if all of the files were up to date. SPS2 is a new frontier and seems to change on a regular basis.

As a note: GM key transponders lock to the IMMO or BCM when programmed, so you cannot use a used key in another vehicle unless it is “unlocked” with tools and software capable of doing so, none of which are OEM. GM also states that you should never install used modules on Global AA or AB vehicles. You can cause damage to other modules on the network and “brick” the car for trying. Here is a…
