Fault codes 4, 3 and 2 are for direction selected before acceleration or parking brake on when driving. Make sure wires to direction select switches in column are ok then check your key switch and battery power. Should not drop below 32 volts under load or you have bad battery. Codes in controllers could be anything it all depends on when they happen according to hour meter now.
