We have no verified code table for this system, so we do not publish code meanings. The exact meaning comes from the manufacturer's diagnostic tool or manual.
Safe test steps
- Record the exact code and when it appears (power-up, load, charging).
- Power-cycle the system; remove/refit the battery; does the code return?
- Inspect external connectors and harness (breaks, corrosion, pushed-back pins).
Tools needed
- Digital multimeter (CAT III, fused inputs)
- Basic hand tools, insulated screwdrivers
- Manufacturer dealer diagnostic tool/software (if available)
Safety
- Power down (remove the battery) before unplugging connectors. Never apply pack voltage to data wires.
