reprogramming a 2017 Chevy malibu
Trying to do an update on a pcm for codes P2097 post catalyst fuel trim system high, code comes and goes and there are 3 tsb's on it when I get to the part to download software the stabilitrac light starts flashing and then it shows an error E6961 unknown error during service program. after 3 tries the next error is E4491 reprogramming error, and E4423. called help desk and they had me switch to internet explorer, did that, reloaded the wrapper. definitely sped up the process as opposed to Microsoft Edge, but still getting the same error codes. anyone run into this? the stabilitrac flashing I don't remember on other vehicles. it wont let me back out of tis either, goes into a constant loop of trying to reprogram.
What tool are you usding to flash with? Had a similar issue on a 2011 Silverado recently. I had to use my MDI instaed of my J tool
snap on passthru pro
I use Mongoose GM Pro. So far any problem yet.
How many miles are on it?
Which Snap On Pro 2 3 4 ???
I use my Cardaq Plus 3 on brand new 2019 GMs weekly ,never any issues. It's the same box as the Snap On Passthru pro 4 as far as I know.
There's a good chance that's your problem. Don't quote me on that but I would bet a newer version J box or MDI2 would be fine. What's your operating system,processor, etc??
I agree. The Snap On pro 2 is quite outdated. You need to be at least using an equivalent of a Snap On pro 3 (J2534-2) On a vehicle this new.
I'm with everyone else and the passthrew is the issue. These newer vehicles have faster networks and would recommend drew tech 3 or MDI.
Thanks for the info everyone. I was able to get it to run through on a loaner. gonna buy a new one tomorrow
Cody, not trying to pick a fight. Just asking a question too learn. Is the High Speed CAN on pins 6 an 14 on a 2017 Malibu really actually faster than say the High Speed CAN on pins 6 an 14 on an 08 Tahoe?? If you look at the Description and Operation on GM SI for both High Speed CAN networks on these vehicles, it will tell you they are both 500kbps. So what's the actual difference?? More data…
Hi Caleb: Since you said "for discussion purposes". I guess "technically" there is a speed difference. Well, there is when the signal doesn't go through. Think this $40 component may have anything to do with it? diag.net/msg/m5on82rckc… Marty can be thanked for that. Guido
