i have a toyota pallet jack that has won the fight so far i have done my homework on it with reading the threads on forklift action

i had a c14 code so i replaced the switches at the base of the arm
now i am able to lift and lower the unit and the horn works however the drive function is not working.... the traction controller has a yellow blinking light on it and i am out of ideas i have checked for broken wires and i need some help with this one...
