DTC P0481: A/C Condenser Fan Control Circuit Malfunction: Condition
WARNING: This page is about a different car, the 2002 Suzuki Esteem. However, it is still accessible from the selected car via links, so may be relevant.
DTC is set when Engine Control Module (ECM) detects that condenser fan motor relay input voltage is low when engine coolant temperature is less than 230°F (110°C) and ECM does not output A/C on signal to A/C amplifier. ECM continuously monitors this circuit. MIL is illuminated when ECM detects malfunction during 2 consecutive drive cycles. Possible causes are:
- Short or open circuit between ignition switch and ECM.
- Condenser fan relay malfunction.
- ECM malfunction.
