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

If anyone needs diodes i have 42 left over can send out to whoever needs some. PM your address, im taking a batch to the PO in a cpl hours 1pm (mountain). Anything after will be sent out on Monday

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.

      Gas fill door

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
