You can turn on your diad with truck running
. Your truck should not be MOVING while you are fiddling with diad, which GPS can prove.
If this is wrong, I stand corrected, but I've never had any warning over diad being turned on while truck is running, do it all of the time.
In my area even if truck is idle and parked you still cant activate diad.
Even if key is turned having power to truck but not started. Think about it. Just like your personal car, if key is turned to power but car not on key turned still powers up your electrics like radio, power windows, etc... Telimatic sensors power up the same way so long as key is turned.
Seat belt on before you turn key. Seat belt stays on till truck is OFF!!!! do not remove seat belt while turning key off cause timing could cause it to flag u. It does happen. Many drivers complained but hey, it is what it is. A pain in the butt.
Drivers even in air ops that have truck on but parked were getting in trouble entering in shuttle codes.
Rule of thumb: do not touch any button on diad while key is turned. Some trucks even have a sensor that knows if Diad has been pulled from it's slot in truck.
If I really need to. I will shut truck off while stoped at light to look at Diad scrolling through a crap trace. Or i will pull over somewhere safe and shut off truck to look at EDD. If I'm desperate and screwed on time commitments I will through the stick in neutral as I roll down a no traffic street turn key off and as I coast I'll quick peak at my trace. That last one is risky and should be done at high descretion with extreme awareness of your surroundings.
if u get an ODS--- shut her down or make them wait.
If you need to relook at your trace--- Shut her down.
If you need to close out a pick up that waves u off cause they have nothing today--- shut her down.
If your board and just gotta touch the DIAd--- Shut her down.
Make shure key is off before you touch the board.
I had a truck for a day that had a problem with bulk head door not staying latched. Every time I hit a bump or did an hard turn just the right way the bulk head would fly open. Telematics flagged the crap out of me that day and even though I wrote up the door I still had to sit in office and explain myslef. I was Peaved!!
I have a habit of leaving my DIAD in my side pouch cause I don't want the extra step of putting it away and then taking it again for my next stop. If I keep it with me at all times it saves me a step. Well, some trucks know when board is not in truck slot so even if you don't use diad it assumes u are handling it cause its not in slot while truck is on. Toke me awhile to get used to putting it in slot every freaking time. Not many trucks have that though but u never know what truck has that sensor and what truck doesn't so save face and assume that it does.
