Condenser Fan Motor Relay: Testing and Inspection
CONDENSER FAN RELAY/CIRCUIT TEST
1. Verify that engine is cold and the A/C switch and fan switch are OFF.
2. Start the engine and let it idle.
3. Verify that the condenser fan is not operating.
4. If the condenser fan is operating, check the short circuit in wiring between condenser fan relay and PCM terminal 40.
5. Turn the A/C switch and fan switch on.
6. Verify that the condenser fan is operating.
7. Turn the A/C switch and fan switch off.
8. If the condenser fan does not operate, do as follows.
(1) Connect the SSTs (NGS) to the data link connector-2.
(2) Select the SIMULATION TEST function on the NGS display.
(3) Turn the condenser fan relay from OFF to ON by using the "A/C RLY" (MTX) or "FANN" (ATX) and check for the condenser fan operation.
9. If the condenser fan operates, check the A/C SW PID.
10. If the condenser fan does not operate, do as follows:
(1) Turn the condenser fan relay from OFF to ON by using the simulation function. Operate the condenser fan relay and check if the operation
sound of the relay is heard.
(2) If the operation sound is heard, check the following:
1. Wiring harness and connectors (Condenser fan relay - Condenser fan motor)
2. Condenser fan motor
(3) If the operation sound is not heard, check the following.
1. Condenser fan relay
2. Open circuit in wiring harness and connectors (Battery - Condenser fan relay - PCM)
1. Remove the relay.
2. Check for continuity between the relay terminals by using an ohmmeter.
3. If not as specified, replace the relay.
