DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK OUTPUT SIGNAL FROM ECM. Turn ignition switch to OFF. Connect test mode connector at the lower portion of instrument panel (on the driver's side), to the side of the center console box. Turn ignition switch to ON. While operating radiator fan relay, measure voltage between ECM and chassis ground. NOTE: Radiator fan relay operation can be executed using Subaru Select Monitor. For procedure, < Ref. to COMPULSORY VALVE OPERATION CHECK MODE . > Connector & terminal (B134) No. 14 (+) - Chassis ground (-):	Is the measured value within 0 to 10 V?	Even if MIL lights up, the circuit has returned to a normal condition at this time. In this case, repair poor contact in ECM connector.	Go to step 2.
2 CHECK SHORT CIRCUIT IN RADIATOR FAN RELAY CONTROL CIRCUIT. Turn ignition switch to OFF. Remove main fan relay and sub fan relay. (with A/C models) Disconnect test mode connector. Turn ignition switch to ON. Measure voltage between ECM and chassis ground. Connector & terminal (B134) No. 14 (+) - Chassis ground (-);	Is the measured value more than 10 V?	Repair battery short circuit in radiator fan relay control circuit.	Go to step 3.
3 CHECK MAIN FAN RELAY. Turn ignition switch to OFF. Remove main fan relay. Measure resistance between main fan relay terminals. Terminal No. 5 - No. 7:	Is the measured value less than 1 Ω?	Replace main fan relay.	Go to step 4.
4 CHECK SUB FAN RELAY. Remove sub fan relay. Measure resistance between sub fan relay terminals. Terminal No. 22 - No. 24	Is the measured value less than 1 Ω?	Replace sub fan relay.	Go to step 5.
5 CHECK POOR CONTACT. Check poor contact in ECM connector.	Is there poor contact in ECM connector?	Repair poor contact in ECM connector.	Replace ECM. < Ref. to ENGINE CONTROL MODULE . >
