ADDITIONAL SERVICE WHEN REPLACING ECM
Description
INFOID:0000000009022480
When replacing ECM, perform additional service.
NOTE:
After replacing with a blank ECM, programming is required to write ECM information. To perform the opera-
tion, always follow the work instructions. Refer to
.
Work Procedure
INFOID:0000000009022481
1.
CHECK ECM PART NUMBER
Check ECM part number to see whether it is blank ECM or not.
NOTE:
• Part number of blank ECM is 23703 -
×××××.
• Check the part number when ordering ECM or with delivered package label.
Is the ECM a blank ECM?
YES
>> GO TO 2.
NO
>> GO TO 4.
2.

ACCELERATOR PEDAL RELEASED POSITION LEARNING
Description
INFOID:0000000009022482
Accelerator Pedal Released Position Learning is a function of ECM to learn the fully released position of the
accelerator pedal by monitoring the accelerator pedal position sensor output signal. It must be performed each
time harness connector of accelerator pedal position sensor or ECM is disconnected.
Work Procedure
INFOID:0000000009022483
1.
START
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch ON and wait at least 2 seconds.
3. Turn ignition switch OFF and wait at least 10 seconds.

THROTTLE VALVE CLOSED POSITION LEARNING
THROTTLE VALVE CLOSED POSITION LEARNING
Description
INFOID:0000000009022484
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 harness connec-
tor of electric throttle control actuator or ECM is disconnected or electric throttle control actuator inside is
cleaned.
Work Procedure
INFOID:0000000009022485
1.
START
With CONSULT
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:
Engine coolant temperature is 25
°C (77°F) or less before engine starts.
2. Warm up the engine.
NOTE:
Raise engine coolant temperature until it reaches 65
°C (149°F) or more.
3. 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.
