ERROR 04/05: Throttle error and throttle does not work
Error 04/05 is a throttle fault. Below are steps to help resolve the error code and throttle issue:
1. Unplug and replug your throttle making sure to line up the arrows and pins to ensure proper connection. Make sure the throttle pins aren't bent or damaged.
2. If Step 1 does not solve the error, unplug and replug all of the connections on your kit Main Wiring Harness (display, throttle, brake levers), including the Main Wiring Harness connection with the motor lead and Battery connections with the motor leads. Make sure no pins are damaged on the Main Wiring Harness and line up the arrows and pins when reconnecting everything to ensure proper connection.
3. If Step 2 does not solve the error, unplug just the throttle from your kit. Does the error go away? If so, you most likely need a new throttle.
