Diagnostic Procedure
1 INSPECTION START
Do you have CONSULT-II?
Yes or No
YescGO TO 2.
NocGO TO 3.
2 CHECK COOLING FAN OPERATION
With CONSULT-II
1. Turn ignition switch ªONº.
2. Perform ªCOOLING FANº in ªACTIVE TESTº mode with CONSULT-II.
SEF646X
3. Make sure that cooling fan-1 operates.
OK or NG
OKcGO TO 12.
NGcGO TO 4.
3 CHECK COOLING FAN OPERATION
Without CONSULT-II
1. Turn ignition switch ªOFFº.
2. Disconnect engine coolant temperature sensor harness connector.
3. Connect 150Wresistor to engine coolant temperature sensor harness connector.
4. Restart engine and make sure that cooling fan operates.

Perform ªTROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENTº.
cINSPECTION END
12 CHECK COOLING SYSTEM FOR LEAK
Apply pressure to the cooling system with a tester, and check if the pressure drops.
Testing pressure: 157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
Higher than the specified pressure may cause radiator damage.
