Just a Quick Rant and Question

Michael Mobile Technician Utah Posted   Latest   Edited  

Called to a shop today that usually does their own programming. They ask me to program a 2012 Cruze with FOB key. New PCM. I start out like normal. Get 50% through programming and the vehicle goes to sleep. Try again with door closed. Turn on emergency flashers. 50% and the vehicle goes to sleep. Turn on radio. 50% and the vehicle goes to sleep. Ended up watching the start button. When it went out I quickly hit it again before the bus went to sleep. Finally got through the programming. Is this why I was called? Did their tech crash and burn? I am sure there are instructions in the service information on how to keep the vehicle alive during programming. Can anybody tell us off the top of their head?

Then comes the second part. Immobilizer. "Put key into programming pocket" Look on Google, it is kind of like Huh? Lots on programming FOBs for door locks. So I dig into the owners manual. There it is, in a triangle shaped cubby under an insert.

Thanks GM, that was easy to find. Follow instructions... I pat my head and rub my belly, turn the key on and off, then it starts doing something. OK, this process is easy, no more 12 minute learn. WRONG ANSWER! The timer starts and I wait. Pat your head, rub your belly, key on, key off, 5 seconds, 10 seconds, HOLD in, WAIT..... OK it is programmed start car. Car starts.

Third Part. Warm vehicle to operating temp. Do crank learn. Reset Oil Life, Reset O2 sensor calibration, I don't remember but I think there was another task. So after 1.5 hours I am done. Customer tapping their foot. Decide not to explain. I just say. "These new ones take a little longer." BTW, the customer only left the shop with one key. I made sure they knew the other keys would likely not work. Hey GM, why not have a process that retains the keys and shares that info with the PCM when programming? Got to love it! 

So GM techs, what is the flat rate on programming a new PCM on this Cruze? I get that after one you know the drill, but lots of busy work to go along with the process.

They eat-it hard on programming at GM. Need three cars going at once to make enough hours to buy lunch. At least according to all the GM dealer techs posting on iATN.

My first rule of programming! Never program with customer waiting 😎

So what do you use for service information then?

I use motologic. I was in a hurry and did not look it up. Most of the time programming is pretty intuitive. I kind of doubt they would have the info anyway. EDIT: I did look in the SI and there was no special procedure for push button start. I have done updates on these and the system only adds the part of the file needed to fix specific problems. With a blank PCM the process takes longer. Maybe…

Hi Mike: There's no "magic voltage" spec across all of the vehicles that I'd bet my life on. While this a was a GM, I've seen different voltages on different modules in the same Chrysler vehicle. I've had situations where I've had to apply a load during programming to get the voltage down because the power supply was kicking it too high followed by programming failure. (Don't misunderstand…

Have you discovered the trick to keep it awake Guido? I think that's what Mike really needs here.

Hi Geoff: Nope, no tricks. I use the service information or the owner's manual. Yeah, I know. There are 2 things that you'll rarely find in a glove box, an owner's manual and a pair of gloves. Seeing you reply to a thread like this is kind of funny in a way. Of all the members in this network, you're possibly the only one who doesn't lose money programming. ;) Guido

By the time he gets to his first one he is going to be terrified. His hands will shake so bad he won't be able to touch the right buttons or keys. lol Sorry Geoff. And It's really not that bad, everyone just makes it seem that way so no one wants to do it. They want to keep all the gravy work for themselves.

I start shaking just thinking about trying anything with Windows. Never ever works for me. Really glad customers never need it but once a year, and there is a guy who can come over on Saturdays from the other side. I watched him once. What a mess. I'd rather be back in the desert getting shot at.

LOL, yeah, I'm morbidly curious about the giant shit-show that programming with Windows seems to be. The simple fact that most of the programs will tell you to update to a version of Java that won't even work is all the "don't try this" incentive I need. Every video I've watched glosses past the parts where I would get lost; like when pop-ups tell you "Windows things" that mean nothing to me.

How were you putting the car into service mode?

Joe, So the original question was how to do this on a 2012 Chevy Cruze? (put the car into service mode) I have yet to find it in Motologic. I am sure it is available in GM documentation somewhere. Of all the GMs that I have flashed, the pushbutton start variety have been the most challenging. All the tricks known to me were described in my post. Obviously I did not use the correct process. I…

Michael i have done various different modules (not PCM) on late model Cruze - Luckily i have not yet ran into this issue --- I am interested in the answer! For what its worth late model BMW you need to keep the drivers seat belt buckled....

Hi Michael, From GM SI - Path -->Power and Signal Distribution-->Wiring Systems and Power Management-->Description and Operation GM Doc 2540116 The ignition mode switch has 2 LEDs that indicate the vehicle power mode. When the vehicle is in the off mode, both LED’s will be off. Pressing the ignition mode switch button once (without the brake pedal applied), the vehicle enters the…

Thanks Scott, I did notice the light went from orange to green. ACC to Run. It seems it was real touchy and it seemed like it was not straight forward getting it to go to green. It was switching from orange to off without going to green. I do remember it being orange during programming so it was in ACC mode. After programming and immobilizer was done it worked normally. -Mike

Identifix has it listed in the Control Module References chart which is a very nice chart that has columns with links to the Control Module?Scan Tool Information, Schematics, Repair Instructions and Programming and Setup for each module. I use it regularly when programming all types of GM modules. The Programming and Setup column link takes you right to the procedure for each module. Looking at…

If you want to put a GM into programming mode (KOEO) with push button start, the best thing you can do is hold down the push button for 15 seconds, the car will never shut off.

Joe has your answer, just hold it down till it comes alive. The other step you missed in your OP was idle/throttle relearn LOL. I just did one earlier this week. One thing I've noticed lately with SPS is the "replace control module" prompt when doing replace and program. It doesn't populate on some cars, like the Cruze I did earlier. I just took it upon myself and replaced after it read the…

Hi Lane, Well, the check engine lamp stays on until it is done. I did not get called back so I would say I neglected to note it in my rant but surely it was completed. Thanks for catching that. -Mike

"Third Part. Warm vehicle to operating temp. Do crank learn. Reset Oil Life, Reset O2 sensor calibration, I don't remember but I think there was another task." I was just harassing ya about the above statement in your original post. No harm intended.
