there a post on this some where , there is a micro switch in the steering column that can cause this problem

there is a video in youtube about this problem which is caused by a ground strap on the passenger side of the truck

here is the wiring diagram, it looks like you have a power problem not a ground issue. trace the wiring to find the voltage drop trailer wiring.pdf

i have tried them all, duracraps ko2 toyo and the trailrunner that came on the truck. i call them duracrap because they are, at 50 percent tread these tires are dangerous in the winter. bought the ko2 and loved the tire until they were at 50 % and they became very loud but still great traction. then i bought the toyo at3 and it is a good tire but tread life wasnt great and had to be replaced with in a year. i put 40k miles on in a year so tires get expensive. my truck came with the trailrunners and they are ok but at 30k miles they wont make it through a canadian winter. so next i am going to try the bfg trail terrain, it is a step down from the ko2 but gets really good reviews

used the block heater on our 2020 3500 a lot and no issues

do not have z71 package

i cut mine in half and put a heavy duty hinge on one side and a slide latch on the other because it is to long for the bed

any shock is got to be better than what comes stock on the RST, first mod i did on my RST was to change the shocks. i just had a ride in a new trail boss with the rancho shocks and thought it rode quite well considering it has duratracs

need new water pump

got these codes yesterday on my 2020 rst, i have a subscription with gm software, could you tell me where to look for version number to know if the update has been done

yep just measured mine it is 3 inch

that sux, fortunately it does not look like any structural damage should be an easy fix if parts are available

i would check to make sure the pvc system is working properly

they are 433mhz and make sure they are for your year of truck, the new trucks are also 433 but will not work

have you tried hooking to a different trailer, some how you are getting a feed back on the trailer camera wires

that code is for the fuel pump driver and is a known problem, easy fix. as for the stupid horn honking my truck does this also and i also have it turned off

thanks for posting the solution

i believe that was for the 8 speeds, i have searched to find that post and cant

wams, whites automotive services

did you have a 5.3 or 6.2

you would have to get it programmed to your vin

i always change the oil when the olm is at 40 percent, with my 2014 5.3 it would use about half a quart oil, my 2020 2.7 doing the oil change at the same time and the oil wasnt even on the dip stick

the oil solenoid reduces the oil pressure, less stress on the pump and better mpg. it wont hurt the engine at all to run it this way

trailer brake module, chassis control module and fuel pump control module, take the part numbers off them and enter them on a gm parts site and it will show which is which

check the air box drain, sound like you are having a freezing problem
