2. Select “HO2S MNTR (B1)”, in “DATA MONITOR” mode.
3. Running engine at 2,000 rpm under no load (The engine is warmed up to normal operating temperature.),
check that the monitor fluctuates between LEAN and RICH more than 5 times during 10 seconds.
Is the inspection result more than 5 times during 10 seconds?
YES >> GO TO 15.
NO >> GO TO 13.
13.CHECK HEATED OXYGEN SENSOR 1 CIRCUIT
Check heated oxygen sensor 1 and its circuit, refer to.
>> GO TO 14.
14.CHECK “A/F ALPHA-B1”
1. Start engine.
2. Select “A/F ALPHA-B1” in “SPEC” of “DATA MONITOR” mode, and make sure that the indication is within
the SP value.
Is the measurement value within the SP value?
YES >> INSPECTION END
NO >> GO TO 15.1 time : RICH → LEAN → RICH
2 times : RICH → LEAN → RICH → LEAN → RICH

NOTE:
If DTC P0011 is displayed with DTC P1111, first perform the trouble diagnosis for EC-219, "
DTC Logic".
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is between 10V and 16V at
idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE-I
With CONSULT-III
1. Turn ignition switch ON and select “DATA MONITOR” mode with CONSULT-III.
2. Start engine and warm it up to the normal operating temperature.
3. Maintain the following conditions for at least 6 consecutive seconds. Hold the accelerator pedal as steady
as possible.
4. Stop vehicle with engine running and let engine idle for 10 seconds.
5. Check 1st trip DTC.
With GST
Follow the procedure “With CONSULT-III” above.
Is 1st trip DTC detected?
YES >> Go to EC-131, "Diagnosis Procedure"
NO >> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE-II
With CONSULT-III
1. Maintain the following conditions for at least 20 consecutive seconds.
DTC No.Trouble diagnosis

NOTE:
If DTC P1217 is displayed with DTC U1000 U1001, first perform the trouble diagnosis for DTC U1000
U1001. Refer to EC-128, "
DTC Logic".
If DTC P1217 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer
to EC-129, "
DTC Logic".
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.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to CO-11, "
Inspection". Also,
replace the engine oil. Refer to LU-7, "
Draining".
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-20, "
SAE Viscosity Number".
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
DTC CONFIRMATION PROCEDURE
1.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-257, "
Component Function Check".
NOTE:
Use component function check to check the overall function of the cooling fan. During this check, a DTC might
not be confirmed.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Go to EC-258, "
Diagnosis Procedure".

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.
DTC No. Trouble diagnosis name DTC detecting condition Possible cause
