Hey guys, 

 

I went into my tail light assembly to hardwire an led tail gate light bar. With what I seemed would be an innocent project had my scratching my head…I went to expose the wire to splice into my light bar wires with the truck turned off. I go to turn it back on and it says “check light assembly. Sure enough no power to the back left but right works just fine….thinking it was a fuse I went in and changed what I believe is the fuse # but still nothing….could I have shorted the whole assembly??

I tapped my marker bar with the clear LED backups into the left tail lamp and the B/U lamp circuit and have never had an issue. I did my 2021 and my 2024 the same way.

you will need a scanner to hook up and clear codes in the bcm, it thinks the light is shorted and turns off the power

 I went in with my own scanner, found a code, deleted it, but check engine light is still on and assembly is still not working. Will a standard OBD-2 scanner not work?

Another quick update. I got the code out and engine light is gone but assembly still not working. Is it really possible I fried the whole assembly now?

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.

      Looking for this part for my truck. They don't sell just that one piece and to get it you have to pay over $100 even used for the whole air tube. The piece the hose clamp snaps into that is held on by the screw and nut. If anyone has access to one please let me know.
