1Was “ENGINE DIAG. FLOW TABLE” performed?Go to Step 2.Go to “ENGINE DIAG.
FLOW TABLE”.
2Check Radiator Cooling Fan Relay and Its Circuit.
1) Turn ignition switch ON.
2) Check for voltage at terminal C02-18 of ECM
(PCM) connector connected, under following
condition. See Fig. 1.
When engine coolant temp. is lower than
92C, 197F and A / C switch turns OFF:
10 – 14 V
Is voltage as specified?Intermittent trouble or
faulty ECM (PCM).
Check for intermittent
referring to “Intermittent
and Poor Connection”
in Section 0A.Go to Step 3.
3Check Radiator Cooling Fan Control Relay.
1) Turn ignition switch OFF and remove radiator
cooling fan relay.
2) Check for proper connection to the relay at
“B/W” and “P/G” wire terminals.
3) If OK, then measure resistance between
terminals a and b. See Fig. 2 and 3.
Is it 100 – 150 Ω?“B/W” or “P/G” circuit
open or short.
If wires and connections
are OK, substitute a
known-good ECM
(PCM) and recheck.Replace radiator
cooling fan relay.

INSPECTION
STEPACTIONYESNO
1Check Fan Control System.
1) Connect scan tool to DLC with ignition switch OFF.
2) Start engine and select “DATA LIST” mode on scan tool.
3) Warm up engine until coolant temp. is 97.5C, 208F or
higher and A / C switch turn OFF. (If engine coolant temp.
does not rise, check engine cooling system or ECT sensor.)
See Fig. 1.
Is radiator cooling fan started when engine coolant temp.
reached above temp.?Radiator cooling
fan control
system is in good
condition.Go to Step 2.
2Check Radiator Cooling Fan Relay and Its Circuit.
1) Check DTC and pending DTC with scan tool.
Is DTC P0480 displayed?Go to DTC
P0480 Diag.
Flow Table.Go to Step 3.
3Check Radiator Cooling Fan Relay.
1) Turn ignition switch OFF and remove radiator cooling fan
relay.
2) Check for proper connection to relay at terminals “c” and “d”.
3) If OK, check that there is continuity between “c” and “d” when
battery is connected to terminals “a” and “b”. See Fig. 2.
Is check result satisfactory?Go to Step 4.Replace radiator
fan relay.
4Check Radiator Cooling Fan.
1) Turn ignition switch OFF.
2) Disconnect cooling fan motor connector.
3) Check for proper connection to motor at “Bl / R” and “B”
terminals.
4) If OK, connect battery to motor and check for operation.
See Fig. 3.
Is it in good condition?“Bl / W”, “Bl / R” or
“B” circuit open.Replace radiator
cooling fan
motor.

REMOVAL
1) Relieve fuel pressure according to procedure described in
“FUEL PRESSURE RELIEF PROCEDURE” of Section 6.
2) Disconnect negative cable at battery.
3) Drain cooling system.
WARNING:
To help avoid danger of being burned, do not remove
drain plug (2) and radiator cap while engine and radiator
(1) are still hot. Scalding fluid and steam can be blown out
under pressure if plug and cap are taken off too soon.
