Worked on my first LMM

[Duramaster]

Had an SES light. P003A, P0401. I ended up replacing the Turbo Vane position sensor for the intermitent P003A and there was some updated calibrations for the PCM already. :)

What do those calibrations do? Just wondering if it fixes some of the minor annoyances...

BTW, if water pools in the bed, it deactivates the rear park assist when you take off. The water falling out of the back of the truck meets one of the criteria for the truck to turn it off.

Also, have you ever turned on the rear camera option for the radio when the truck didn't come with it from factory? I want to add a rear camera and even the aftermarket company (coastaletech) says I have to have the dealer reprogram the truck for it.

Thanks,
