My 2018 has an anti-sleep function and built-in seat and steering wheel massage.   To activate the anti-sleep function, just get up to cruising speed on the highway.  The vibrating and deep

I couldn't figure out what what going on when my high beams started turning on by themselves, I later found out that if you double tap the brights it turns the auto high beam feature on/off.

I wasn't even towing and as I was coming to the bottom of the Ben Franklin Bridge I looked at the DIC and saw "Grade Brakjng Activated", not sure why.

While towing my new travel trailer last week, slowing down for a turn, slight downhill but not braking, the truck suddenly down-shifted and revs went up to 5,000+.

 

Looked down and the DIC said "Grade braking activated". Cool! I thought that was only on diesels.

 

EXHAUST braking is only on diesels.  All the new GM trucks have GRADE braking.  It works differently between "regular" mode and Tow/Haul mode.  You can also turn it off if you don't like it but you need to do it each time the truck is started.

 

The operation of it is explained in the owners manual ...

I apologize in advance if this is a duplication but when I get a phone call on my paired Samsung Note 8, it displays the phones' battery status and signal strength on the screen. :)

MY 18 displays the phone vitals and Wi-Fi strength in the top left hand corner of the nav/radio screen at all times.

Likewise when connected via CarPlay. But it’s different on the intellink screens vs when you’re in the car play screens. Like in intellink it shows battery life, on CarPlay it only shows signal strength and data type at the left side above the home button:

Don't use Car Play, just connected with Bluetooth.

 

Think this feature started with the introduction of Wi-Fi in the trucks.

When traveling with my dogs, I always put them in the bed. I have a rubber mat on the floor to keep them from sliding around and have a topper on it. I have the sliding rear window on the cab and the windows are tinted. I usually have the slider opened as well as front window on the topper so I can try to keep an eye on them. Besides the bed lights, I have a dome light on the topper that is hooked up via the bed lights. At night, especially with the tinted cab sliding window, it is very hard to see what they are doing back there. I knew that while moving, just pushing the cargo light switch wouldnt work. Just for kicks, I tried switching into neutral while rolling down the road, and sure enough, the bed lights and topper dome light came on. Now I can check on them any time I want at night.

The bed lights don't work while in gear?  Weird.

Thought about that… Probably to keep the overhead centermounted cab high light from shining in the faces of drivers behind you.

Good to know, when someone comes up behind me with their high beams on I turn on the cargo lamp. Worked great in my 2001 Sierra, didn't know it was disabled in the newer ones.

Today, I remote started my ‘15. 

 

It wasn't until I unlocked the doors, got in, turned the key and shifted to drive that I was alerted the right rear door wasn’t fully closed. 

 

I didn’t think it would start under that circumstance.

Navigation top green icon on radio screen changes with direction. 

 

I always payed attention to the cluster and after 1.5 year of ownership just noticed it changes on radio screen as well.

      2023 DRW Wheel Liners

      By SFC Retired · Posted

      Did have to make 1 modification because of the WeatherTech rear mud flaps and that was needing 3 longer screws than what came with the install package. 😄

      Picked up the liners yesterday. Installed passenger side WITHOUT any modifications. All mounting holes lined up perfectly. Rain is interfering today with drivers side. Very Happy! Will add pics when finished

      OCI, not when but why?

      As a matter of amusement I’ll leave this conversation with this. Do you beat the government average fuel estimate? Statistics are a guide to me. Not a rule. Someone once said I have to have the last word. If true and possible may be. I’ll blame that on working in a family business.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That is a fair point, and I agree that trying to log “everything in the truck” would be the wrong direction.   There are a lot of modules and a lot of traffic. If the product became a full-truck datalogger, the amount of data would get huge very quickly, and most owners would never use it.   I think the first useful version would need to be narrow: - powertrain-side event evidence - selected high-value parameters - communication / voltage / reset events - pre/post event window - short report first, raw log only as backup   One distinction I should make is between active OBD/PID polling and passive bus capture. If you are polling PIDs through OBD, then yes: the more parameters you request, the lower the effective sample rate becomes, and you are adding diagnostic traffic to a vehicle that is already busy running itself. With passive CAN capture, the recorder is not asking all the modules for data. It is listening to traffic that is already on the bus. So it does not consume vehicle bus bandwidth in the same way that a scan tool polling hundreds of PIDs would. But your point still applies in a different way.   Even if passive capture does not add bus traffic, the recorder still has limits: - processing rate - storage rate - timestamp accuracy - decoder workload - event filtering - report size - user attention span   So the answer cannot be “log everything and let the user figure it out.” The product would need to store enough raw evidence to be useful, but only decode, graph, and present the important parts around the event.   A practical report should probably show: - what triggered the capture - how much pre/post data was preserved - which selected parameters changed - how those values compared to baseline - whether the same pattern happened before - whether any voltage, reset, bus-off, lost-message, or communication fault occurred - selected graphs around the event - raw data only as supporting evidence   So I agree with you. More data is not automatically better. The real product is the reduction from raw data into a useful event report.

      By bluev8 · Posted

      That makes sense, and I agree with most of that.   I think the product would need both: 1. a default powertrain template, so it is useful out of the box; 2. user-selected priority parameters, so the owner or shop can choose what they want to see first.   Different users are going to care about different things. One owner may care about oil pressure and voltage. Another may care about misfire trend, AFM/DFM behavior, or U-codes. A shop may want communication events and repeatability first. Your baseline point is probably the most important one. Raw data is not very useful unless the report can show what normal looked like for that vehicle under similar conditions.   The way I would think about it is: - start with a basic known-good baseline - learn normal behavior for that specific vehicle over time - allow the event to be overlaid against baseline - show whether the event was a one-time spike or a repeatable pattern - provide a simple severity level, but with clear limits on what that severity means   For example, early severity could be something like: - Info: event captured, no obvious abnormal pattern - Watch: value moved outside baseline, but not repeated - Warning: repeatable abnormal pattern under similar conditions - Critical: communication loss, voltage drop, bus-off, reset, or severe repeated event   I would not want the first version to say “replace this part.” That would be overclaiming unless there is repair-confirmed data behind it. It would be more honest to say “this pattern deserves inspection.”   On the OBD port question, I think OBD absolutely has a role. OBD is probably the right place for: - DTCs - freeze frame - VIN - calibration information - normal scan-tool parameters - Mode 6 / enhanced diagnostic data if available The reason I am still looking at an ECM-side recorder is that the failure may happen before anyone connects a scan tool. If the owner plugs in a scanner after the event, the pre-event evidence may already be gone unless the ECU happened to save it. So I do not see this as “OBD versus ECM-side.” I see it more like: - ECM-side recorder: always armed, rolling buffer, event evidence - OBD/DLC companion: DTCs, freeze frame, VIN, calibration, normal scan data - phone/cloud: status, notes, upload, report generation, notifications   I agree that phone connection and push notifications would be useful. I just would not want the phone or cloud connection to be required for capture. The recorder should save the event locally even if the phone is not connected. The phone should help with event marking, download, notes, upload, alerts, and report viewing.   For a default GM V8 event report, would this list make sense? - RPM - calculated load / MAP - throttle position - vehicle speed - gear / torque converter state if available - coolant temperature - oil pressure - oil temperature if available - battery voltage - commanded AFM/DFM state if available - actual AFM/DFM state if available - misfire counters / roughness by cylinder if available - fuel trims - relevant U-codes / communication events - bus-off / lost periodic message / module reset / voltage drop events Which of those would you remove, and what would you add?
