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 leave a high fan control circuit unresolved because fan run-on and battery drain can result.

Useful checks before replacing parts

Review fan 3 command, control voltage, relay state, fan module feedback, coolant temperature, A/C request, charging voltage, and freeze-frame data.
Inspect for short-to-voltage faults, stuck relays, open grounds, melted connectors, damaged fan module wiring, and backfeed from prior repairs.
Verify whether fan 3 or the related speed stage remains energized when not commanded and isolate relay, module, and harness branches.
