based on the confirmed symptom in
step 4, and determine the trouble diagnosis order based on possible causes and symptoms.
>> GO TO 10.
10.DETECT MALFUNCTIONING PA RT BY DIAGNOSIS PROCEDURE
Inspect according to Diagnos is Procedure of the system.
NOTE:
The Diagnosis Procedure in EC section described based on open circuit inspection. A short circuit inspection
is also required for the circuit check in the Diagnosis Procedure. For details, refer to GI-46, "Circuit Inspec-
tion".
Is a malfunctioning part detected?
YES >> GO TO 11.
NO >> Monitor input data from related sensors or check voltage of related ECM terminals using CON-
SULT. Refer to EC-613, "Reference Value"
.
11 .REPAIR OR REPLACE THE MALFUNCTIONING PART
1. Repair or replace the malfunctioning part.
2. Reconnect parts or connectors disconnected during Diagnosis Procedure again after repair and replace-
ment.
3. Check DTC. If DTC is displayed, erase it.
With CONSULT: Refer to “How to Erase DTC and 1st Trip DTC” in EC-601, "CONSULT Function"

THROTTLE VALVE CLOSED POSITION LEARNING
THROTTLE VALVE CLOSED POSITION LEARNING
DescriptionINFOID:0000000009462555
Throttle Valve Closed Position Learning is a function of ECM to learn the fully closed position of the throttle
valve by monitoring the throttle position sensor output signal. It must be performed each time the harness con-
nector of electric throttle control actuator or ECM is disconnected or electric throttle control actuator is
cleaned.
Work ProcedureINFOID:0000000009462556

1. Turn ignition switch ON.
2. Select “CLSD THL POS LEARN” in “WORK SUPPORT” mode.
3. Follow the instructions on the CONSULT display.
4. Turn ignition switch OFF and wait at least 10 seconds.
Check that throttle valve moves during the above 10 seconds by confirming the operating sound.
WITHOUT CONSULT
1. Start the engine.
NOTE:
Coolant temperature is less than 25 °C (77 °F) before engine starts.
2. Warm up the engine. NOTE:
Warm up the engine until “COOLAN TEMP/S” on “DAT A MONITOR” of CONSULT reaches more than
65 °C (149 °F).
3. Turn ignition switch OFF and wait at least 10 seconds.
NOTE:
