With the harness from Gen5DIY, is it correct that you would need to manually turn on the fog lamps while on low beam in order that they fogs would be on when activating the high beam lights?

This was on the Duramax forum. I believe it is for a GMT 900. But the principles are likely applicable to a K2. Use this information cautiously. ------------------------------------------------------

OK, After struggling thru the schematics and online mods of past models all evening, I figured it out. This is for a Sierra and should be the same for the Silverado. It involves pushing one Diode in

Does this work on 2016?

 

Anyone perform this on 2016?

 

We're the cable colors/locations different?

 

And issues with the BCM or electrical?

I literally just created an account to thank you all for the help. I can't even describe how easy this was to do... I have some of those smz vled headlights on back order so I'll post an updated picture then, but this is how it looks now... And I dig it

I just did the 10-22 on my 2016 Silverado LT and it works perfectly. The fog light wire at pin 10 was brown and the parking light wire at pin 22 was blue. The locations are exactly the same as previously mentioned in this thread. As far as the issues with the BCM, I would remove the diode whenever having the truck at the dealership to avoid any complications that people were having.

So did you get it to work?

unfortunately not

I read one post where the person used some wire cutters on the diode and cut the wire on an angle which put sort of a pointed end on the wire which made it easier to insert into the plug.

You guys having difficulty inserting the diode may want to try sharpening the lead with a file or snipping it on a steep angle like mentioned above. Also, try moving around the socket/pin to another side. These sockets/pins can be pulled over to one side or another. Another thing to look at is the gauge (diameter) of the lead on the diode. Some are smaller than others. I don't think the diode size is critical in our application. Buy a smaller one.

I have been performing this mod since whenever fog lights started going off when you turned on the high beams.

 

I would like to say that I was the originator of this mod as I used to sell diodes with instructions at local car and truck meets, swap meets and over the counter at my parts counterman job.

 

It's good to see someone started posting this online - it's probably one of the coolest mods you can do to a Chevy Truck.

can this be done with a resistor instead of a diode? used all my diodes and have a bunch of resistors lying around

NO!

 

Think of a resistor as a flow restrictor orifice and a diode as a one way check valve.

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.

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

      By bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
