RESISTANCE AND CONTINUITY BETWEEN HARNESS-SIDE CONNECTOR TERMINALS 1. Disconnect the connector A-02, and connect special tool ABS Check Harness
(MB991970) to the wiring harness-side connector.
2. Measure the resistance and continuity between the terminals indicated in the
table below. NOTE: Do not measure terminal voltage for approximately three
seconds after the ignition switch is turned "ON." The ABS-

TEST B: RADIATOR FAN & CONDENSER FAN DO NOT CHANGE SPEED OR STOP Technical Description The fan control module has variable control of the radiator fan motor and the
condenser fan motor speeds using signals transmitted from the PCM. Troubleshooting Hints
Malfunction of fan control relay. Malfunction of fan control module. Malfunction of PCM.
Diagnosis 1. Check the fan control relay. See FAN CONTROL RELAY
under
COMPONENT TESTS. If fan control relay is okay, go to next step. If fan
control module is damaged, repair or replace as necessary and retest.
2. Check the harness wire between terminal No. 2 of fan control relay connector
A-10X and terminal No. 3 of fan control module connector A-18. See Fig. 7

and Fig. 8
. If wiring is damaged, repair or replace as necessary and retest. If
wiring is okay, go to next step.
3. Disconnect all the connectors from the PCM. Connect Power Plant ECU Check
Harness (MB991923
) between the PCM and the bod
y-side harness connector.
NOTE: If the engine coolant temperature reaches 230°F (110°C) 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 position. The fan stops its rotation when the engine
coolant temperature decreases to 230°F (110°C) or l ower.
NOTE: Measure the output circuit voltage at terminal No. 10 of
PCM connector B-18 by using Power Plant ECU Check
Harness (MB991923). See Fig. 11
and Fig. 12
.

5. If repair or adjustment is not possible, replace the door assembly.
POWER WINDOW TIMER FUNCTION CHECK After the doors are closed and the ignition switch is turned to the "LOCK" (OFF)
position, the power windows should work within 30 seconds. The timer expires if
the front door is opened during that 30 second time. If it does not, carry out the
timer troubleshooting in SYMPTOM CHART
.
POWER WINDOW OPERATING CURRENT CHECK 1. Remove the power window fuse and connect an ammeter as shown in the
illustration.
2. When the power window switch is pressed in the "UP" position, a large amoun
t
of current flows from the time the window starts to close until it is fully closed,
Measure the current during this time
Standard value (A): 5 +/-1A [Power supply voltage 14.5 +/-0.5V, 25°C (77°
F)]
3. If the operation current is outside the standard value, refer to INPUT SIGNAL
CHART

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
.
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 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.]
