Hi guys,
Had an operator pinch the battery cables in the battery door today, which shorts to frame, blows fuses, etc,
In many cases, it blows one of the control boards in the process, and the odd time this happens, we replace the (visibly fried) board and it usually solves it,
In this instance, one of the fuses blew, so we replaced it. The truck powered on when the key switch is flipped,
Displays no codes, when you try any of the functions at the control lever, drive, lift, tilt, etc, the truck will start beeping (like there is a trouble code) but NO CODES ARE DISPLAYED, ONLY BEEPING (when controls toggled, no beeping when controls are idle)
Swapped every control board with known working ones, checked all fuses, swapped battery, examined most of the wiring visually,
nothing appears to be out of place,
No error codes, only an error-code-like beeping from the display when you toggle the drive or lift controls,
Any ideas guys? This one has me stumped... Only thing I can think of is some damage occured to the wiring somewhere... but I went through all the input tests, and the control board(s) are reading all control inputs just fine!
Dead man is okay too.
Ideas?

sounds like you put the truck back to how it was supposed to be with your battery short repair. maybe someone had something jumped out before you did the right thing? have fun with the csi.
well as an update, managed to fix this one, although I don't know if I can explain it,
So these trucks have a 3-wire key switch, half these toyota trucks in our fleet have an aftermarket keyswitch retro fitted, with only 2-wires hooked up,
They seem to operate just fine, and thats how this one was working, FINE, until today, with just two-wires hooked up to the keyswitch,
Well out of just dumb luck, stripped the third, unconnected keyswitch wire, and touched it to one of the keyswitch posts...
yea this somehow brought all the functions back to working condition... go figure... how it was working completely fine on just two wires at the keyswitch until today's massive short... is a best guess until i look a bit closer...
