Electronic Throttle Control Actuator Self-Learning Procedure: Vehicle Setup Condition
• Engine stopped and the ignition switch on.
• Vehicle speed is 0 km/h.
• The Engine Coolant Temperature (ECT) is between 5.25°C and 100.5°C.
• The intake air temperature is more than 5.25°C.
• The accelerator pedal fully released.
• Battery voltage is more than 12 V.
Self-Learning Operating Procedure
Perform the following procedure to activate Self-Learning:
• Turn the ignition switch ON for 10 seconds.
• Turn the ignition switch OFF.
NOTE :
During the procedure, don't operate any other components.
Self-Learning Components
Self-Learning should be performed if the following service procedures have been performed:
• After replacing the ECM.
• After disconnecting and reconnecting the ECM.
• After replacing the Accelerator Pedal or Electronic Throttle Control Actuator.
Self-Learning Condition
The self-learning condition is known as the Electronic Throttle Control Actuator Self-Learning Condition .
CAUTION:
Ensure that the Electronic Throttle Control Actuator self-learning procedure lasts for at least 10
seconds according to the Electronic Throttle Control Actuator self-learning condition. If the self-
learning procedure fails, the engine cannot be started, or the EPC lamp will be lit. If this condition
occurs, the self-learning procedure should be performed again after the DTCs have been erased in
ECM.
