WITH CONSULT-II
1. Start engine and warm it up to normal operating temperature.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Hold engine speed at 2,000 rpm and check one of the following.
–“HO2S1 (B1)/(B2)” voltage should go above 0.70V at least once.
–“HO2S1 (B1)/(B2)” voltage should go below 0.21V at least once.
If the check result is NG, perform EC-469, "
Diagnostic Proce-
dure" .
If the check result is OK, perform the following step.
4. Let engine idle at least 5 minutes.

On Board Diagnosis LogicABS006VA
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.
This self-diagnosis has the one trip detection logic.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to CO-11, "
Changing Engine
Coolant" . Also, replace the engine oil. Refer to LU-9, "Changing Engine Oil" .
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-13, "
Anti-Freeze Coolant Mixture Ratio" .
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckABS006VB
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.
