The G3 is equipped with an onboard diagnostic system and can display four different error codes for crucial components.

Throttle error is displayed or no response?

If the throttle is not responding, ensure the brake levers are being reset fully and pressing on the kill switch. If it is not being pushed in, remove the Phillips screw from underneath the kill switch and realign positioning.

You must remove the breastplate and verify that the three-wire connector is still connected. A replacement throttle may be necessary if connected, and an error is still displayed. If the throttle powers the unit but the gear selector control is not changing when pressed, verify that the three-wire connector is seated correctly.

Controller or motor error displayed?

Remove the breastplate, ensure all wire connections are made, and the three Molex plugs are connected.

Brake kill switch error code displayed?

The icon will display every time the brake is applied; this tells the controller to cut the power to the throttle and motor, reducing speed. If the code is displayed with brake levers in the “neutral” position, ensure the brake levers are being reset fully and pressing on the kill switch. If it is not being pushed in, remove the Phillips screw from underneath the kill switch and realign positioning.
