Hi, my name is ***** ***** you for asking your question, I will try and help you out.
In order to change passwords you need the dealer passwords unless you can guess the old customer passwords.
I'll give you some tips at getting it to go through,, it's worth a shot instead of paying Dealer to come out.
Not always do they install customer passwords,, it comes from the factory with anyone of the following passwords,
all 1's then go through up to 9 so try them all
Next we used to use the last part of truck serial number for customer passwords, so whatever tech went out to fix the truck would be able to guess them or use serial number.
Now if you know what dealer used to do the work on the lift truck (they always install stickers on truck or paperwork under cover)
use just the initials of the company,,then initials with a 1,,2,,ect.
So if the name of repair place was mikes lift truck repair use passwords MLTR,,MLTR1,,,ect
We used initials 1 for customer passwords,, and initials 2 for dealer passwords.
If you can't get it the only other way to get this done without the Dealer is install a new personality module,,it's just a control board,,if you do end up doing it this way don't pull board until you get new one,,then with battery removed change it,,note do not turn on key with board unplugged.
The only other option is have a Dealer tech come out and hook up laptop to change parameters which usually runs around $250 depending on how far they have to drive and what their labor rate is.
Hope this helps.
