DTC CONFIRMATION PROCEDURE
1.INSPECTION START
Is it necessary to erase permanent DTC?
YES >> GO TO 6.
NO >> GO TO 2.
2.PRECONDITIONING
If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following proce-
dure before conducti ng the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.
>> GO TO 3.
3.PERFORM DTC CONFIRMATION PR OCEDURE FOR MULFUNCTION A-I
1. Start engine and warm it up to normal operating temperature.
2. Turn ignition switch OFF and wait at least 10 seconds.
3. Turn ignition switch ON.
4. Turn ignition switch OFF and wait at least 10 seconds.
5. Start engine and let it idle for 5 minutes and 10 seconds.
6. Check 1st trip DTC.
Is 1st trip DTC detected?
YES >> Proceed to EC-803, "Diagnosis Procedure".
NO >> GO TO 4.
4.PERFORM DTC CONFIRMATION PR OCEDURE FOR MULFUNCTION A-II
With CONSULT
1. Select “DATA MONITOR” mode with CONSULT.
2. Check that “COOLAN TEMP/S” indicates above 70 °C (158 °F).
If it is above 70 °C (158 °F), go to the following steps.
DTC No. Trouble diagnosis
(Trouble diagnosis content) DTC detecting condition Possible cause
P0196 EOT SENSOR
[Engine oil temperature (EOT)
sensor circuit range/perfor-
mance] A)
Rationally incorrect voltage from the
sensor is sent to ECM, compared with
the voltage signals from EOT sensor
and intake air temperature sensor. • Harness or connectors
(The EOT sensor circuit is open or
shorted)
• EOT sensor
B) The comparison result of signals trans-
mitted to ECM from each temperature
sensor (IAT sensor, ECT sensor, FTT
sensor, and EOT sensor) shows that the
signal voltage of the EOT sensor is high-
er/lower than that of other temperature
sensors when the engine is started with
its cold state. • Harness or connectors
(High or low resistance in the EOT
sensor circuit)
• EOT sensor

1st trip DTC might not be confirmed.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Proceed to EC-803, "Diagnosis Procedure"
.
6.PRECONDITIONING
If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following proce-
dure before conducting the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
• Before performing the following procedure, do not add fuel.
• Before performing the followin g procedure, check that fuel level is between 1/4 and 4/4.
• Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.
>> GO TO 7.
7.PERFORM DTC CONFIRMATION PROCEDURE B
1. Start engine and let it idle for 60 minutes.
2. Move the vehicle to a cool place.
NOTE:
Cool the vehicle in an environment of ambient air temperature between −10 °C (14 °F) and 35 °C (95 °F).
3. Turn ignition switch OFF and soak the vehicle for 12 hours.
CAUTION:
Never turn ignition s witch ON during soaking.
NOTE:
The vehicle must be cooled with the food open.
