I was wondering if one could put a switch on the VSS wire so that I could flip it off while at speed in order to be able to input NAV data without having to stop? If I do, then flip the switch back on, how long would it take for everything to begin working normally?

 

Installing the lockpick/unlockharnesswill achieve the sameresult with much less effort!

 

I realize that, but dont want to spend the money for a lockpick because I really dont use the Nav all that much, but a cheap little switch would allow me to use it on the road in the few instances that a passenger could enter data while driving.

Anyone know how long it would take for all the Nav stuff to go back to normal if I "switched" the VSS wire off and then back on?

Thanks

Should work but will trigger a DTC. The nav unit will either go back to normal operation immediately or on the next key cycle.

 

What is a DTC? And how long would it take to get to the next key cycle?
Thanks

DTC = diagnostic trouble code (warning light on instrument panel).

The next key cycle is when you shut the truck off and restart it.

 

Lets say it trows a code. Will it reset itself when the VSS is reestablished or is it something a dealer will have to correct?

Thanks

Light will stay on for a while or next key cycle and then the problem will be stored in memory for a while but poses no other problem for you.

Judging from your concern my advice is don't monkey with it, get the Lock Pick.
