I'm 12 hours from home with the family on vacation.

 

2016 Sierra SLE and up until this trip everything has worked correctly with connection to my phone.

 

Now I get a "Communication error 8" when I try plugging my phone in after a brief disconnect of the battery.

 

Bluetooth showed as available for just a moment and now I can't get it to connect.

 

I checked with the GMC dealership where I'm at and their response was to buy a new stereo or a new truck.

 

How can I reset or get the radio to work with my phone again?

If you are talking about the trucks battery, maybe disconnect it for a longer period of time to allow all components to completely discharge, then try it again.

I am disconnected the battery and left it disconnected for 30 minutes before trying this again. And result is the same I'm still not able to connect my phone to Android auto and the truck and getting a error screenshot included. I've tried three different cables.

How old is the battery in the truck?

 

When they start to fail, it will cause all kinds of weird electrical issues.

Did you check the date and time settings of your truck? including time zone?

it has to match your phone.

 

Communication Error 8

This means authentication failed between the car and the phone. This can happen when the date and time are set incorrectly in your vehicle’s display. Try the following:

• Park your car, unplug your phone, and go into your vehicle’s date or time settings.

• Set the date and time to the correct information. Check that your car radio has the correct time zone set up. If it allows time zone settings, check if your vehicle has winter or summer (daylight) setting and make sure it matches the setting on your phone.

• Reconnect your phone after confirming the new information is saved — you should be good to go!

• If it still doesn’t work, please ensure that Google Play Services is up to date  and try again.

I had manually set the time and then clicked for it to sync over cell network. No option for time zone.

 

I had turned the truck back on and connected the phone again and it's once again working.

 

Thank you all for your help!

 

The following includes what steps were required for mine to connect and work again1. Disconnect the battery for 30 minutes

2. Remove the connection to my phone

3. Connect via Bluetooth

4. Set time and date, then select to sync automatically

5. Wait 10 minutes while the redio plays and the Bluetooth is on.

6. Turn truck off and on again. 

7 connected successfully via USB and android auto

 

Wheeeewww

      Bench seat swap for 2021-2024 suburban

      By davester · Posted

      probably won't get a response from that user, as they haven't returned to the site since making that one post.  users don't (at least I don't, and I haven't seen any setting which would notify me via say, email) get any notification other than going to this site, and checking if they got a response on their thread...

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

      By Atlas · Posted

      Thanks - I wasn't quite caffeinated this morning. 2:1 makes sense, turning the crankshaft 360 degrees will turn the cam 180 degrees, and had I done that, the cam's dot would be at 6 and the crank's at 12 again.   I went ahead and took the sprocket off anyway, aligned everything dot-to-dot including the balance shaft just for s&g. I'm glad I did because I discovered no Loctite on the timing sprocket bolts. Maybe it's not required, but at only 20 ft-lb torque spec, those bolts aren't in there very tight. Cleaned and reassembled with some thread locker and torqued.   A general observation: Less is more with RTV. If a little doesn't stop a leak, a LOT probably won't, either. RTV is thinly veiled revenge, in a tube...

      The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge

      Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).

      PF63 Oil Filters Going Away?

      By Grumpy Bear · Posted

      The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.
