Gen2/System Warning Sequences

This is a quick lookup for the red sequences flashed by the dash System Warning Indicator (a red triangle with an exclamation mark within it).

These are derived from the Official Owners Manual only for roadside reference and owner community annotations and links.

Overview

The red indicator light in the lower part of the display sometimes will flash a repeating sequence.

The Official Owners Manual lists what they mean, usually related to system startup.

Often enough, keying the bike off and on is the way to re-test.

System Warning Troubleshooting

1. Toggle the Instrument Cluster's Display A to show Error Codes.
2. Check the corresponding Error Codes

   Some will be expected like kickstand down based on your context.

   Focus on topical system errors related to the System Warning.

3. Attempt a basic reboot:
   1. Charging: disconnect the external power source from the vehicle.
   2. Key the bike off.
   3. Wait several seconds or a minute in length depending on severity of the error.
   4. Key the bike on, checking for a normal startup sequence, contactors closing, and no errors.
4. If the System Warning persists, and it is related to the BMS, perform a BMS Reset Procedure (soft and then hard reset).
5. If the System Warning persists, attempt to extract MBB logs.

   Urgent/Roadside: Email logs to yourself, then decode using a log parser.

   Non-Urgent or Important: Email logs to Zero.

6. If no clear resolution is at hand, contact Zero and/or your local dealer to schedule servicing.

Warning Blink Sequences

#	Blinks	Description	Cause	Guidance
1	············	Fast constantly	Safety Override is Active
	· · · · · · · ·	Fast intermittently	BMS Isolation Fault	Check the BMS Isolation Fault section of the manual Moisture and/or dirt are the most likely culprits.
	— = 1 long Charge Indicator blinking fast constantly or all blinking dash segments		Charger Not Charging	Probably a CAN Error Unplug the bike and wait a minute to re-engage
	—	1 long	Cutout switch engaged or Kickstand Switch Disabled	Disengage the cutout switch and/or raise the kickstand.
2	··	2 short	Self-test failed
