When I turned the key on, it would show the Precharge Fault and and High Pedal, which both cleared up after the precharge completed and the led stopped flashing. However, the contactor would not close.The led stayed on and would start flashing on applying throttle. However, the contactor would not close.

I have been trying to trace the fault. With the controller on the bench again, I checked the voltage at pin 2 of the optoisolator U9, and it reads 4.91V on switching on and 3.75V after precharge. There is no change at pin 4 though.
