The 3582 and 3543 are basically the same and deal with the SCR conversion efficiency. Since there is a 3748 present I would ignore those 2 faults. For the 3748 there is basically no troubleshooting. The troubleshooting directs you to replace the intake nox sensor.The 3712 and 3714 are just derate faults due to the other fault codesI would replace the intake nox sensor and then manually clear all of the faults. The 3582/3543 will not go away without manually clearing them.Thank you for providing the engine serial number. I was able to see that there is an open campaign for your engine. It involves replacing the SCR even if you don't have warranty coverage. I would advise that you replace the nox sensor and then take the truck to a dealer to have the SCR replaced under the campaign.
