I just picked up a set of 2022 ZL1 seats for my 2018 RCSB and I know the truck has to have the heated seat option so the BCM knows to trigger the heat signal in order to make it plug and play in any way. 

 

Since White Auto isn't currently modifying BCMs to turn that signal on, I'm trying to think outside the box in order to get the heat and cooling feature in the seats to work. 

 

What I don't know is how the actual on/off is triggered for the respective features works. (negative/positive switched relay?) 

 

I'm getting ready to install an Alpine ILX F511 head unit and they offer an accessory that adds "switch" options. 

 

I'm pretty sure the Alpine's KAC-001 (External Accessory Control Module) runs a negative switch relay system, so I'm wondering if we can simply bypass the BCM, and wire the heat/cool feature to a relay that activates the heat and (separately) the cooling system in the seats and control it with the head unit. 

 

That's not as desirable as being able to use the factory switches, but it'd be a great start towards making the seat functionality improved above simple forward/back/up/down/tilt

 

Thanks for looking!

I have zero to offer,  just interested in the seat fitment.  Any pics? 

 

They actually bolt in directly. (the seat base is exactly the same as the 14-18 Silverado, as far as I can tell)

 

Getting the seat to move and articulate doesn't seem to be a huge issue either, but getting the heat and cooling to work is the real trick. 

 

Not my pics or video

If the wiring is the same you should just need to swap out the switches for the heat/cool switches and add the 2 wires between the two seats.

It looks like the truck has to have the BCM command to control the seat heaters and so far it doesn't look anyone's figured out how to get the cooling circuit to work. (you need to already have the heated seat option from GM.)

 

For now, I'm going to work on getting the seats installed and working, and I'll worry about the heating and cooling features once White Auto has some availability.

Oh. I misread the post I thought you had heated seat function in the truck. I put 2020 yukon denali seats in my 2014 sierra.  But I had heated seat capabilities already.  

Do the camaro seat have adjustable lumbar support and manual reclining?

I'm not 100%,but I'm pretty sure they're power lumbar and reclining, but I'm not 100% on that. 

 

I'd look, but they're at my place in south Florida and I'm in NC right now, or course. 😕

Ok, let me know what you find out when you get home.

Quick Google says no lumbar, which blows my mind.

Well that is some crap. Maybe you can cannibalize the truck seats and put it in the camaro seats.

Once I get them back to the truck (I keep the truck in NC), I think I'm going to strip both seats and see what kind of alignment I can get from harness to harness. 

 

In another post, someone said the harness was a direct swap and most things worked, so I'll see what I get, take some pics, and report back once I'm sure. 

 

I really need to focus on one project at a time, is the real issue. 

 

I'm flying back to Florida to drop an LS2 408 into a 2002 Z06 and if I can get it tuned, I may try to drive it back with the seats for the truck stuffed inside. 😁

Nice. I hear you with the one project at a time. They tend to get away from ya some times.

Did you ever get the seats to NC and work on this project?  Curious to find out how the seats worked out.

      I hope to high heaven this is wrong. My Chevy farm trucks frame is lasting way longer than a newer Nissan Titan XD I got for a steal, and it only pulls trailers. A decade younger and it's frame is already way rustier than the waxed Chevy I drive across longs and ditches. Also, hasn't Ford been having tones of troubles with rusted frames?

      Batteries don’t always show signs of a few years ago my vehicle started fine in the morning and took me to work. After work the battery was completely dead and I needed a jump. No, I didn’t leave anything on and the battery was only a couple months old. It was replaced under warranty.

      AFM is confirmed in the Corvette engine, so I'm assuming the higher volume trucks will get it as well

      If his battery was that bad I would think it would have been showing signs before this that were ignored. Stinks that it happened the way it did in rush hour traffic, but this seems like a pretty fringe scenario. I don't mind it that bad and never turn it off. The only slight annoyance for me is the slight delay between brake to gas, but I have gotten used to it and figure if it can save a little gas why not.

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

      By bluev8 · Posted

      That is a good correction. I think “severity” was probably the wrong word for what I meant. What I really mean is closer to event priority, relevance, and actionability — not “this code is severe” or “replace this part.” I agree that a truck can have a lot of trivial or historical communication codes, and if the product starts pushing alerts for every stored or low-value event, people will ignore it very quickly. So the alert logic would need to be filtered. For example, I would not want a random old communication code to generate a push notification by itself. A useful alert would probably need to be based on things like: - new vs historical - active vs stored - repeated vs one-time - duration of the event - whether it happened near the driver-marked symptom - whether it happened together with voltage drop, reset, bus-off, misfire, oil-pressure change, etc. - whether the same pattern repeats under similar conditions So instead of saying “severity,” maybe the product should organize events by affected system and priority. For example: Misfire event: Show misfire counts / roughness first, then fuel trims, RPM/load, DFM/AFM state if available, coolant/oil temp, voltage, and related DTCs. Oil-pressure event: Show oil pressure first, but only in context — RPM, load, oil temperature, coolant temperature, DFM/AFM state if available, voltage, and baseline comparison. Communication event: Show which module/network/message dropped, whether voltage dropped, whether the recorder reset, whether it was active or historical, and whether it repeated. Voltage/reset event: Show battery voltage, crank/wake/sleep state, module reset, communication dropouts, and what came back online first. That also solves the display-order problem you mentioned. The main report should not always show the same fixed list first. It should show the system that appears abnormal first, and then the supporting values for that system. I also agree that the truck already has an oil pressure gauge and MIL. The point would not be to duplicate those. The value would be in showing what else was happening before and after the warning or symptom. For example, if the MIL comes on for a misfire, the truck already told the driver there is a problem. The useful part would be: - which cylinder or bank looked abnormal first - whether it happened after an AFM/DFM transition - whether fuel trims were already moving - whether oil pressure or voltage changed at the same time - whether the same pattern happened previously without a MIL On the OBD port point, I think you may be right for a consumer-facing version. OBD is much easier for the average owner: - easier install - easier removal - inside the cabin - easier phone connection - easier data download - easier to include a pass-through port for another scanner OBD is also the right place for DTCs, freeze frame, VIN, calibration information, Mode 6, and normal scan-tool parameters. The reason I was looking at ECM-side recording is that some events may be gone by the time someone plugs in a scanner, and some powertrain-side network evidence may not be available the same way through the DLC. But I agree that if an OBD-based version can capture enough useful evidence for most owners, that is probably the cleaner consumer product. Maybe the split is: - OBD/DLC version for most consumers - ECM-side version only if it proves it adds evidence that the OBD version cannot get - shop/pro version if deeper powertrain-side event evidence is actually useful So I would not want to force the inline approach if the OBD workflow solves most of the real-world problem. Your last point is probably the key product requirement: the report should be specific to the system showing the abnormality. Not “here are 50 parameters.” More like: “Misfire-related event detected. Here are the misfire/fuel/DFM/context values.” or “Oil-pressure-related event detected. Here is oil pressure compared with RPM/load/temp/baseline.” or “Communication event detected. Here is what dropped, when, and whether voltage/reset happened first.” That is a much better way to think about the report.
