2. Turn the ignition switch ON (II), and select the PGM-FI, INSPECTION, and then RADIATOR FAN on the HDS.
Does the radiator fan and the A/C condenser fan run?
YES - Fan Circuit is OK.
NO - Go to step 3.

3. Turn the ignition switch OFF.
4. Disconnect the radiator fan control (RFC) unit 3P connector.





5. Check for continuity between RFC unit 3P connector terminal No. 2 and body ground, then terminal No. 3 and body ground.
