Q: What does code P1502 mean?

Radiator Fan Function Problem. P1502 on a Subaru means the engine control module (ECM) has detected a problem with the radiator fan circuit, typically an open, short, or unexpected voltage on the fan control wire. The ECM commands the fan on and monitors the circuit through the fan relay or control module, and when the feedback does not match the command, it stores this code and may illuminate the check engine light.
