Ok fellas I took in my 2014 GMC Sierra for an oil change today and see about the PI1288a update for the radio. I have in the past complained to them about the radio's reception. I was told by the service advisor that the PI1288a did apply to my truck but the radio sounded fine to him so their was nothing he couid do. I went to pick up the truck and on the way home guess what fm radio breaking up and sounds muted at times and yes the auto volume is turned off. What do I do now?

I would have the service tech ride in the car with you, and take him to the areas where you know the radio sounds like crap. He can't hide from that

If you are having problems with the dealer call GM infoteam support (the number is in your manual) they will give you a problem number and even contact the dealer for you.

 

This is what dmd277 posted when I mentioned about trouble with the dealer.

Well my radio had bad reception. I was messing around with it yesterday and found a new button may have been there all along. But I haven't noticed it. With radio on press menu go to update channel list press wait for it to finish scanning. Now all kinds of channels come in. Hope this helps some of you guys.

Thanks David. Did this help you receive NEW channels/stations or did it help bring in those you already were receiving better or both?

My radio receives the stations I want to listen to, they just drop in and out.

I asked this a couple of times already in this thread and no one ever answered my question so I will try again to get an answer if someone knows

 

 

is this radio problem specific to just one or two types of radio or displays is it only in certain equipt packages?

 

I have a basic 2WT package so is my radio the same type as those having problems? I don't have issues ATM

I don't know the answer to your specific question. I have the Bose radio with navigation and based on the signatures of others in this thread, I suspect it is all over. I drove a loaner basic model and it had the same issue. If this helps, tbarn posted the update document in post 685 with RPO codes. If your is listed, this probably pertains. You can always send a PM to tbarn for more info (he is a GM tech).

ok, thanks

 

im in process of lemon law buy back for vibration and was trying to understand if this was across the whole line of trucks or just limited to a certain radio package kind of thing.

 

I haven't ruled out another Silverado (2015 cause i'll never get another 2014) and just trying to understand the equipt that is involved so I can see if things change for the 2015's

One thing about the radio is in 2015, they won't have HD...could be they are giving up on it..

I called GM they said they had no idea why the service department did not at least do the PI1288A update they were just as confused as I was. The representative with GM called me back and told me she talked with the dealership and they could not give her a straight answer as to why they did not at least install the radio update being that the problem does not have to be duplicated in order to do just the update but it does have to be duplicated in order for GM to replace the module unless the CET Technician sees fit to replace it. So know I have to take it back in this Sat. to get the update I hope this helps some since I'm wasting my time to go back to the dealership and get them to do what they should have done to start with.

My truck - 8/13 build has a radio p/n of 13591992 Another truck, build 6/14 has p/n 13592804. Mine supersedes to the later number. What anyone can extrapolate from that I don't know. part numbers change all the time and for many reasons. There ya go. Use the info as you wish.

I took my 11/2013 built truck to the dealer on 09/14 so they could apply PI1288A. I told the dealer of the update and even gave them the PI #. They only did a software update and didn't replace the radio module. The HD and FM reception was slightly better but nowhere near what it should be. I spoke to the Service manager by phone and he told me to bring the truck back in so they could change the module. I took the radio module out of the truck and took a photo of it so I will know if it was changed. The part number for my module is #13592715 and it was made 10/2013.

 

I then searched my radio module # online and found this link:

 

http://www.gmpartsgiant.com/parts/gm-radio-13592715.html

 

It appears that my module is now replaced by part #13592804, I would assume that this is the newest module. The truck is currently at the dealer and I am driving a Cruze rental with great reception.

 

I went ahead and picked up a powered amplified antenna and a new connector from Crutchfield that will allow me to plug in a new antenna to the factory radio. If I get the truck back and the reception is still bad I will be bypassing my factory antenna altogether.

Interested in the results for sure.

      Wow I'm in a pickle. (Broke down truck) and a story.

      I will be doing that for sure, but I need to solve who has/ where I can find a bidirectional scan tool that will support OBD 1.5. I'm kicking myself because I ebay'ed a Snap On MT2500 that I didn't think I'd ever need anymore. D'oh!! I'd rather not buy another, so I'll contact a few local shops to see if they have one and how much they'd want to do the procedure. I'd rather have the ability to do it myself... I wish there was a modern tool that could do it all, but I'd have no idea what to buy.   The theory with the pulled timing is that it mimics a rich condition. The delayed spark causes incomplete burn and the O2 sensor picks up low oxygen levels. That's interpreted as a rich condition so the PCM pulls fuel and that shows up in the deeply negative fuel trims.

      An ultra wealthy man had the most beautiful daughter. But, there was a problem. Everything she touched would melt in her hands. No matter what, Metal, Wood, Stone. Anything she touched would melt. She could not feed herself. Because of this, men were afraid of her. Nobody would dare marry her. Her father was despaired. What could he do to help his daughter? He consulted doctors, scientists and anybody who could solve this problem. Finally one of them said, "If your daughter touches one thing that does not melt in her hands, she will be cured." He was overjoyed and came up with a plan. The next day, he held a competition. Any man who could bring his daughter an object that would not melt in her hands would be given billions of dollars to marry her. Three extremely intelligent and handsome young men took up the challenge. The first brought a very heavy steel rod, But alas, when the she touched it, it completely melted in a matter of seconds. He sadly went away. The second brought a beautiful diamond, knowing diamonds were one of the hardest substance in the world and would not melt. But alas, once she held it in her hand, it melted. He too was sent away disappointed. So now, there was one left He was very nervous & sweating. He approached the daughter & said, “put your hand in my pants pocket and feel what is in there." She did exactly what he asked. She felt something very hard. She held it in her hand, squeezing it as hard as she could. It did not melt & remained extremely hard. Her father was overjoyed. Everybody was overjoyed. She was finally cured. Nothing never, ever melted in her hand again. They married and they both lived happily ever after, raising a wonderful family. Question: What was in the the groom’s pants pocket??? Answer below ↓ M&Ms of course! They melt in your mouth, not in your hand. What on earth were you thinking?

      There's a bunch of tea leaves that you've read, but in any case the delayed timing is unusual. Not sure how that relates to the rich at idle vs. 'normal' while driving.   If you're in this deep, might be worth investigating, and re-learning the sensor. What have you got to lose? Plus, it properly fixes the timing cover leak.

      The only problem I have seen this cause is longer crank times.

      Injector is being sent off today for rebuild and I estimate I'll have it back in 10 days or so.   It may not be the injector...of course...now that I've torn down the intake again. But, let's rule out the injector and replace those spider legs that have been almost rubbed through.   The truck has always had negative timing and I'm reading "normal" timing at warm idle should be +16 or so. I'm negative 16 to 25 or more, and it's always been like that since I bought it.   A light turned on upstairs last night in the old noggin. Rare, I know...   This will be wild, if it turns out to be the cause!   In 2001, according to the old service documentation, the muffler was replaced. Why? I have no idea, it wouldn't have been rusted through by then. But they did a crappy job.   In 2019, another shop replaced it and noted the prior install was poorly done on the work order. "Exhaust system vibrates on crossmember". Except...I guess they just left it be? I believe the husband, the couple who were original owners, had passed by then. Maybe she said it's just not worth it to have the exhaust system fixed and declined repairs. Very few miles were driven between 2019 and 2025.   The exhaust system vibrates heavily on the crossmember and you can feel it and REALLY hear it, even today. Not always, but at idle, it gets going pretty good sometimes.   What if....   ....What if that's enough to trigger one or both of the knock sensors? Could it be tricking the sensors into sensing knock, so it's pulling timing aggressively? Pulling timing heavily means it's firing after the piston reaches full height which means incomplete burn which means the O2 sensor is sensing a rich condition, which means I've been chasing my tail, and what I thought was an inconsequential problem (janky exhaust) has been THE issue for this truck for 25 solid years?   That would be wild. Maybe it IS wild.   The service documentation thereafter, for years, shows visits for rough idle, replacing O2's, replacing the cat, replacing plugs and wires, a misfire condition, like they could never solve the issue. The injector has been replaced 4 times in 80k miles, that's just crazy.   The secondary theory....   The engine has clearly had a leak at the front seal for a very long time (the greasy trench...). I think the truck changed hands quickly ~2025 because there's Napa receipts from someone I don't recognize in the ownership history. They apparently replaced the timing cover seal, and they did a terrible job. There's RTV smeared all over and the leak I had reduced to a weep by snugging the front oil pan bolts is now a leak again.   HOWEVER....I read about replacing the crankshaft position sensor. Any time the ckp sensor is disturbed or timing cover is removed, the truck requires relearning, and that can only be done through a bi-directional scan tool. Skippy with the RTV probably didn't do the relearn procedure is my guess. His scan tool is lost in a pile of RTV goo somewhere.   So, it's very possible the sensor has been disturbed and the truck is just running on the old learn data but not setting a code for anything. The distributor has since been replaced and so has the camshaft position sensor, so all bets are off for that thing.   In the theme of one step forward, two steps back, I returned the accumulator for the AC. The gal I've been working with at O'Really's has been great. She refunded it under manufacturer's defect and we compared it to the replacement I ordered, and sure enough, the replacement is machined very differently (and a gauge actually fits on it!).   Got it home, installed it, started vacuuming it down.... and I couldn't get good vacuum.   The high side service port, where I replaced the old GM ball valve suspecting that was a source of the previous leak....well, I've clearly exposed whatever pre-existing crack in the line where the service port is welded, and made it much worse. Blessing in disguise? Except there goes another $25, now I'm waiting for a replacement AC line.   In 10-ish days ALL the parts will be here. Rebuilt injector, new exhaust system, new cat, new high pressure AC line.   Oh, did I mention the squeaking ISN'T coming from the AC pump? The truck still squeaks when started, and there were words after I started it with the new AC pump installed. But, there was more to replacing the AC pump for just a squeak. A truck with good working AC is something of value, for the comfort alone.   I've ordered a new harmonic balancer because, 30 years is a good run for one of those. Rule it out. The squeak may be something more sinister, though. I'm worried about that ckp sensor and if it was shimmed correctly, or if the timing set was installed correctly. The squeak may be coming from UNDER the timing cover.   At this point, once I get it put back together, I'm thinking I'll take a 50 mile victory lap and then promptly put it up for sale. This truck is cursed. Betty, from beyond the grave, doesn't want anyone messing with her Blazer. Or maybe she's getting revenge for 30 years of shop visits with that thing.
