that truck has an EV100LXT control system
the error codes are the same as any EV100 system

-code 2 or (-02) is a directional (forward) switch closed on power up

-code 4 or (-04) is 'start switch input low after initial start up' , it could be either fwd or reverse switch closed on power up, excessive leakage from TB2 to battery negative.

-code 7 or (-07) is 'accelerator input voltage too high', cause could be an out of adjustment accelerator input or defective. Open circuit between TB1 and battery neg in accelerator input circuit. A short circuit from battery positive to wiring in accelerator input circuit.

hope this helps, good luck :o)

Fact of the week
Bluetooth is named after the 10th-century Viking king, Harald Bluetooth, who united warring tribes in Denmark and Norway. In 1997, Jim Kardach from Intel gave the name to the technology because of its ability to unite different communication protocols, just as Harald united various tribes.
