CIRCUIT OPERATION
The fan control module is powered from fusible link number 2. The PCM judges the required revolution speed of radiator fan motor and
condenser fan motor using the input signals transmitted from A/C switch,
automatic compressor controller, vehicle speed sensor and engine coolant
temperature sensor. The PCM activates the fan control module to drive the
radiator fan motor and condenser fan motor.
TECHNICAL DESCRIPTION
The cause could be a malfunction of the fan control module power supply or
ground circuit. The cause could also be a malfunction of the fan control module or the PCM.
TROUBLESHOOTING HINTS
Malfunction of fusible link Malfunction of fan control relay Malfunction of MFI relay Malfunction of fan control module Malfunction of PCM Damaged wiring harness or connector
DIAGNOSIS Required Special Tools:
MB991223: Harness Set MB991923: Power Plant ECU Check Harness
STEP 1. Check the circuit at fan control module connector A-23 (terminal
3).
1. Disconnect fan control module connector A-23, and measure at the
harness side connector.

.
STEP 14. Check the symptoms.
Q: Do the radiator fan and condenser fan operate correctly?
YES: The procedure is complete.
NO: Return to Step 1 .
INSPECTION PROCEDURE 4: Radiator Fan and Condenser Fan do not Change Speed or Stop Radiator Fan and Condenser Fan Drive Circuit Refer to INSPECTION PROCEDURE 3: RADIATOR FAN AND CONDENSER FAN DO NOT OPERATE

condenser fan motor using the input signals transmitted from A/C switch,
automatic compressor controller, vehicle speed sensor and engine coolant
temperature sensor. The PCM activates the fan control module to drive the
radiator fan motor and condenser fan motor.
TECHNICAL DESCRIPTION The fan controller has variable control of the radiator fan motor and the condenser
fan motor speeds using signals transmitted from the PCM. TROUBLESHOOTING HINTS NOTE: If the engine coolant temperature reaches 110°C (230°F) or
higher, the radiator fan control runs the radiator fan for up
to 5 minutes even after the ignition switch is turned to the
"LOCK" (OFF) position [the fan stops its rotation when the
engine coolant temperature decreases to 110°C (230° F) or
lower.]

NO: Replace the radiator fan motor. Then go to Step 7.
STEP 7. Check the symptoms.
Q: Do the radiator fan and condenser fan operate correctly?
YES: The procedure is complete.
NO: Return to Step 1 .
INSPECTION PROCEDURE 5: Radiator Fan does not Operate TECHNICAL DESCRIPTION The cause could be a malfunction of the radiator fan motor or an open circuit
between the fan control module and the radiator fan motor. TROUBLESHOOTING HINTS Malfunction of radiator fan motor DIAGNOSIS Replace the radiator fan motor. INSPECTION PROCEDURE 6: Condenser Fan does not Operate Radiator Fan and Condenser Fan Drive Circuit Refer to INSPECTION PROCEDURE 3: RADIATOR FAN AND CONDENSER FAN DO NOT OPERATE
