<\/figure>\n<\/div>\n\n\nCause<\/h3>\n\n\n\n\n- One or more components connected to the CAN bus have no connection to the CAN bus or are defective. Components connected to the CAN bus:
\n\n- Omni<\/li>\n\n\n\n
- Controller (MCU)<\/li>\n\n\n\n
- Supernova M99 Pro Lighting (ST2S, ST5 and ST7*)<\/li>\n\n\n\n
- Distribution Board (ST5, old version 2018)<\/li>\n\n\n\n
- Blubrake ABS (for models with ABS)<\/li>\n\n\n\n
- Battery
starting around November 2023 with the Supernova M99 Pro 2 and without a CAN bus
<\/li>\n<\/ul>\n<\/li>\n\n\n\n - Poor contact between the battery socket and the Rosenberger connector in the battery compartment below, or the charging socket in the down tube above, e.g., due to dirt, metal particles, water, or corrosion<\/li>\n<\/ol>\n\n\n\n
Solutions to:<\/h3>\n\n\n\n\n- Kontrolliere alle Steckverbindungen zu den Stromerkomponenten (Supernova, Controller etc.).
Um eine defekte Komponente zu identifizieren kann man den SIT (System Integration Test bzw. Test Runner) im Servicemen\u00fc verwenden.

For corrosion on the socket or charging connector, use isopropyl alcohol and a fiberglass brush for cleaning.
