Switch the dash display 1 to the error code display to see a cycling list of the 2-digit error codes currently in effect.
- Check the official manual for what they mean; some are normal safety interlocks and others are about various systems.
- The following are paraphrased interpretations of those codes with (progressively) some basic troubleshooting leads to follow.
|Code||Description (official)||Manual Section||Community Notes|
|0||No Error||Almost abnormally normal!|
|1||High Throttle||Throttle||Likely throttle connection or potentiometer issue|
|2||Motor Temperature Warning Stage 1||Motor||Near upper temperature limit; corresponds to blinking temperature light on the dash|
|3||Motor Temperature Warning Stage 2||Motor||Reached upper temperature limit; might involve cutbacks or shutdown|
|4||Controller Temperature Warning Stage 1||Controller||Near upper temperature limit; corresponds to blinking temperature light on the dash|
|5||Controller Temperature Warning Stage 2||Controller||Reached upper temperature limit; might involve cutbacks or shutdown|
|6||BMS Throttle Enable Wire Error||Throttle|
|7||Low Battery Voltage||Contactor Limits||Should only happen near/below 0% SoC or 84V dynamic pack voltage.
|8||High Battery Temperature Status||Contactor Limits||Can happen during a >4kW charge or while operating at speed in a hot environment.
|9||Low Battery Temperature Status||Contactor Limits||Can happen in winter storage; will prevent charging.
