N00b Questions You (Probably) Have But Were Afraid To Ask!

3) DEF is urea and water (basically urine. i.e. Pee) it is used to convert compounds in exhaust to more environmentally friendly gases. The truck is programmed to D-rate if the process is not taking place. Other than the programming and the possibility of the filter becoming clogged it is not truly necessary to the function of the engine.you could remove the filters and erase the programming concerning the DPF system at the engine would work fine

DEF is made from synthetically produced urea at a much higher concentration than found in urine mixed with deionized water. It also has less byproducts in it than urine. Just in case anyone else was wondering if they could pee in their DEF tank.

Regarding locking differentials, G-Town says:

I also use it when dropping a load at any Walmart with a pitched dock ramp (down towards the bay doors). Otherwise when spanning the crest of the "hump", after dropping the trailer, might be spinning your wheels.

Well, that enlightens me about the docks at Menards. I wondered why I could not escape their force field; I engaged the Diff Lock and drove right out of that hole but did not know why it happened.

Also,

Always, always, always turn this "on" or "off" only when completely stopped.

Why?

Gears.

There's nothing​ resembling synchromesh there.

Local NW drivers use channel 17 on the CB. I usually have my radio set to scan 19 and 17.

Most of the trucks I have driven,...cruise control is disabled when the wipers are on. There are signs all over our driver's area; "no cruise control in the rain or snow".

Actually - ALL TRUCKS have this as a feature set in the ECU Feature set. It's typically enabled by most every company - but it CAN actually be turned off (so that you CAN use CC with the wipers on).

If you're in weather adverse enough to use the wipers, you need to be ALERT & ENGAGED - not relaxed with your feet up on the dash & the CC on.

Primes truck will run on cruise with wipers on. Found that out in training. I tried it on both my trucks cause I read that before.

The only time prime trucks won't run cruise is when the radar plate gets covered with ice or dead bugs.. Then you gotta scrape them off....eeeewwwww yuck lol

Interesting...

Have a friend that works for a smaller company, doesn't hire newbs - and his truck shuts CC OFF when the wipers are on.

Kinda surprised Prime, with it's large number of inexperienced drivers, would leave CC enabled in potentially adverse conditions.

Hmmmmmm...

So if there's a little bit of rain you have to sit there holding your foot on the floor for 11 hours a day? Yeah, I think he needs to let his experienced drivers drive the trucks.

Do they disable the jake brakes when it's raining, too?

I never use cruise control. I don't find it tedious at all to keep my foot in it.

Really? It's just cool to sit there holding your foot on the floor for 11 hours for no reason? I don't see the point, but I don't see the harm either.

In a light rain tapping the windshield washer button will invoke the wipers but not interrupt CC
