Possible causes

- Connector or cable fault
- Internal component fault
- Software/configuration mismatch
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).
Workshop reference values

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.
