INSPECTION AND ADJUSTMENT EC-123 < BASIC INSPECTION > [QR25DE] C D E F G H I J K L M A EC N P O >> GO TO 9. 9. PERFORM IDLE AIR VOLUME LEARNING Perform idle air volume learning. Refer to EC-124, "Idle Air Volume Learning" >> END VIN Registration INFOID:0000000009480758 DESCRIPTION VIN Registration is an operation to registering VIN in ECM. It must be performed each time ECM is replaced. NOTE: Accurate VIN which is registered in ECM may be required for Inspection & Maintenance (I/M). OPERATION PROCEDURE With CONSULT 1. Check the VIN of the vehicle and note it. Refer to GI-24, "Identification Number" . 2. Turn ignition switch ON and engine stopped. Accelerator Pedal Released Position Learning INFOID:0000000009480759 DESCRIPTION Accelerator Pedal Released Position Learning is an operation to learn the fully released position of the accel- erator pedal by monitoring the accelerator pedal position sensor output signal. It must be performed each time the harness connector of the accelerator pedal position sensor or ECM is disconnected. OPERATION PROCEDURE 1. Make sure that accelerator pedal is fully released. Throttle Valve Closed Position Learning INFOID:0000000009480760 DESCRIPTION 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 the electric throttle control actuator or ECM is disconnected or electric throttle control actuator inside is cleaned. OPERATION PROCEDURE With CONSULT 1. Turn ignition switch ON. 2. Select “CLSD THL POS LEARN” in “WORK SUPPORT” mode of “ENGINE” using CONSULT. 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.
