Diagnostic boundary
A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.
Do not replace the fan motor before checking relay, fuse, control, and ground paths; a control-circuit fault can stop a good fan.
Useful checks before replacing parts
- Check fan fuse, relay, control module, fan motor current draw, ground path, and connector condition.
- Command the fan with a scan tool if supported and compare command state with voltage and fan operation.
- Inspect related coolant temperature, air conditioning pressure, and system-voltage data that influence fan command.
