I have a 2013 GMC Sierra 1500 that the stereo went Waco in. It goes into the scan mode on it's own, and I cannot use the stereo at all. I purchased a used stereo from Ebay, but I need to know how to unlock it. Does anyone here know how to do it without getting ripped off from the dealer? My stereo is pictured below.

Would this scanner work on my 2013 Sierra? They don't indicate which software it comes with, but they say "Latest Software" https://www.ebay.com/itm/Tech2-Scanner-Diagnostic-tool-for-GM-cars-trucks-SAAB-etc/254841357062?_trkparms=ispr%3D1&hash=item3b55ba8306:g:mvwAAOSwAXhgCkN2&amdata=enc%3AAQAFAAACcBaobrjLl8XobRIiIML1V4Imu%2Fn%2BzU5L90Z278x5ickkrDx%2B2NLp21dg6hHbHAkGMZNLKY93QliFSiF%2Fr4bsN11zNFtEldo8es%2BBPzyx3tboT6V8DLC0Hjxy30PIodTM1iZfc8wnf0pchfixtLM4lFhfl12Ydb7ihr3iXxLpV0CHkGMz2HzdNz3sYXKIezR4vbGvDrVX7fGiPdXkUw8eRTQUhHC%2BUgBCtROIJj7IU3J4ulcins6gOja5a0XkeW7NHAdLlTI50UXgVSMrzyM4BWg3LkzhKiKClzxnvGpdkVJYgClwUrxxMaIzA9S45KQSiJ0fqs9YXb06nggvuWwkZ4ivKDC1PCqAy%2BMjmgTpSfYVTWl5BvkSzA8rYk0OkmtOqMshNxImEIT1hWRi0eX46547h8v3%2FPgSPnL70n%2B7bRYZI5aSd6XKdVLuayvN6T6hFZri6%2B0qadXuKWDIhzMjrss9TzMQNLObJJxVGVfX4Q8K%2F%2FrfODmtnDSqluraWFRBvxEhvqYEwxdXN0V25RywJ0SY8Gve7oHMKEkr8SMMgbOQtELkOQvXAs0C7Cf9Z%2FcINHxb6zDeBjmrt%2BskF8mYpQoqqdQn%2BbbaOSkBBt6jTX%2BfbAuwia6wpp6%2BxVQrnO5%2FH%2BdaCdxmtjiXctyUBTaSJne%2BZV0k2nFKvfdNrzKZpUmSxjbix8cf2JWuHeYndrG%2BG8MRWubWf6JZrx5iss%2FPSvnOlZkJ4gZ5lItafoPTJPZo%2BEvbC6Ou2ekHRVeIiCuoYqajP9ORcAohRQsI13RGG6OCMUF4MVc7rClr5rKLd0w3Ro6XIzgnXDIMCUokXOxiLQ%3D%3D|cksum%3A254841357062d4e0abf72add400890ba8e2672896b1e|ampid%3APL_CLK|clp%3A2334524

I'm between a rock and a hard spot on this. I thought the dealer would be able to figure this out. My only hope now to get this solved is that the new mechanic next week can get to the bottom of this. This has gone on way too long.

I think you are right Cameron, and I don't relish the idea of another $2000 to install cats and not fix the problem. I talked with a different mechanic shop, and they want to look at it next Friday. So from what you have said, and the fact that both Oxy sensors responded when they squirted brake cleaner into the intake and got 800 MV spike, maybe it's the ECM.

Hi guys . I took my truck back to the Chevy dealer today, and they did a free diagnostic. They are still insisting it's the Cats causing my problem. They said the got these codes.: PO155 / P0059 / P0050 / P0154 They want $1750.00 for the parts plus labor to install the Y pipe. I trust you guys more than ny dealer at this point. Let me know what you think now.

Hi everyone. I took my truck back to the Chevy dealer today, and the still insist it's the Cats causing my problem. They said they found codes PO155 / P0059 / P0050 / P0154 Here is their Diagnosis. Please let me know what you guys think. I trust you more than these guys. They want $1750.00 just for a Y pipe ..... plus installation.

I found a little shop in Missoula with a good reputation, and he's going to try and figure it out. It seems I'm just getting the P00530 code now with the running poorly after it is driven, shut off, then run again. I'll suggest what you said to him and see what he says.(If the wiring for the O2 sensors is good, then it is time for a new ECM.)

I just had the 2 front sensors out and swapped them around. I didn't see any oil on the sensors, and they are brand new Delco sensors. Something is causing it to set the codes and to run very poorly.

I have to agree that the Cats are probably not the culprit. Everyone I have talked to has said these after market Cats work just fine. I don't know what to do at this point. I arguably paid the bill and picked up my truck today. It still misses and runs crappy just like before, especially when I drive it, then park for a while, then drive it again. Code P0050 was reset when I parked it and started it again at home. Could it possibly be something like one of these and the shop tech just doesn't know what he's doing?

So this is where it stands now. They found Codes PO523 / PO155 / POO59 and POO50 ..... All on Bank 2 Sensor 1 They charged me 8 hours labor total, and they did not find the main problem with the mis-fire. Most of the $800 plus labor was their diagnosing the misfire, and they didn't fix it. They blame it on the after market cats. I am happy with the tranny flush, and the door wire fix. Tell me what you guys think. I am desperate here.

This is my bill from our dealership. 3 pages, so I will have to do 3 posts $1000.00 and they say now that it's the aftermarket Cats causing the problem. And the codes are still on.

Well, I took my truck to the Chevy Dealer in Missoula (Karl Tyler) and here's what they're telling me. They found the oil. cap missing, I have no idea what happened to that. They say this could set off codes and there was a code on bank 2. They cleared the codes. They are saying that the Cats I had installed are not original GM Cats, and that I need to install the factory Cats. I paid almost $600 for these Cats, and paid a muffler shop $250 to install them. They told me the parts alone for them to install GM Cats is over $1700

I just watched a video on the GM Tech2, and it looks like I would be wasting my money unless I took a course on how to use it. I only have Apple Mac and iPd also.

I swapped the Front 02 Sensors last night. I'll drive to town today and see if that P0030 code comes back. Where can I buy one of those Tech-2 meters?

Swap the Front, not the Rear sensors? Also, on the battery, I was getting the PO420 code before I changed the battery, but I'll have this new one checked.

I installed a new battery just a couple of weeks ago at Walmart. The PO420 code was coming on before that though. Wow, this sounds like a bit more than I am capable of doing because I don't know how to do anything with my scan tool except erase codes. Maybe I should just take my truck to a dealer and have them put it on the scope at $125.00 an hour. I forgot to mention, my oil pressure gauge quit working also. Since I have the BCM, maybe I should go ahead and replace it. I was told that after install, I just need to turn the key on and let it learn the key code. Is this correct?

I mentioned all my other electrical problems to a friend tat is pretty sharp on GM trucks. These are other issues I am having right now: 1. Cannot set clock on radio. Other radio buttons don't work such as some favorites buttons. 2. Driver's door does not turn on courtesy light, radio plays for 20 minutes after exiting. 3. Cannot get one of my parking assist sensors to work, brand new. Service parking assist displays on dash and I have to scroll out of it every time I drive the truck. 4. Driver's window does not work part time. 5. Oil pressure gauge stopped working. 6. Truck misses and runs poorly after warmed up, then parked for 10 minutes, and re-started. Any way, he said it sounds like a bad body control module.. Could this be causing that issue? I will try swapping the two rear 02 Sensors. I have a brand new OEM Body Control Module to install, but have not put it in yet.

OK Guys, Here's an update. I had the new Y Pipe installed, and now I'm getting a P0030 Code. My engine is still Mis-Firing after I drive to town, shut it off, and go in a store. When I come back out of the store and start it up, it misses for about a block, then straightens back up. I have replaced all 4 O2 sensors with OEM Sensors. This is really starting to get to me. Could this be a probelm with the Body Control Module or possibly Engine Control Module?

I have looked at the plug and terminals, and cleaned them with contact cleaner. There is nothing touching the sensor. ........ Still nothing.

Can someone tell me where the BCM model is located on my truck? And, does this look like the right module?

I should get the Cat Y-Pipe any day now.

I have a Cat Y pipe ordered. I don't know why it takes 2 or 3 weeks to get it. Must be coming across the pond on a rubber raft from China.

I replaced a sensor that wasn't working, but I have one that doesn't work even after replacing it. Can someone shed some light on this and help me out?

OK, got my new thermometer today and measured the temps on driver side Cat at Front - 421* Rear - 437*
