SYMPTOM PROCEDURES
13Ad-73
INSPECTION PROCEDURE 27: A/C condenser fan is inoperative
.
CIRCUIT OPERATION
• The battery positive voltage is applied on the
PCM (terminal No. 17) from the condenser fan
motor relay.
• When the PCM switches on its power transistor,
the condenser fan motor relay coil is energized,
causing current to flow in the circuit.
.
TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are: )
• Malfunction of the condenser fan motor relay.
• Malfunction of the condenser fan motor.
• Improper connector contact, open or short-
circuited harness wire.
• PCM failed.

DIAGNOSIS
STEP 1. Check harness connector D-132 at PCM for
damage.
Q: Is the harness connector in good condition?
YES : Go to Step 2.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then confirm that the
malfunction symptom is eliminated.
STEP 2. Measure the output voltage at PCM harness side
connector D-132.
(1) Disconnect the connector D-132 and measure at the
harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 17 and ground.
• Voltage should be battery positive voltage.
(4) Check the condenser fan condition.
• When the terminal No. 17 is disconnected, the fan
should stop.
• When the terminal No. 17 is grounded by the jumper
cable, the fan should run.
(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the voltage and fan condition normal?
YES : Replace the PCM. Then confirm that the malfunction
symptom is eliminated.
NO : Refer to GROUP 55, Introduction To Heater, Air
Conditioning And Ventilation Diagnosis
