Learning Procedure For Idling In MFI Engine

ENGINE IDLING LEARNING PROCEDURE

PURPOSE

When the ECM is replaced, or when the learned value is initialized, the idle may not be stabilized. Carry out the learning method by following the procedures below.

LEARNING PROCEDURE

1. Start the engine and warm to reach 80°C (176°F) or more.
NOTE:
When the engine coolant temperature is 80°C (176°F) or more, the warm-up is not needed if the ignition switch is in "ON" position once.

2. Turn the ignition switch to "LOCK" (OFF) position.

3. After 10 seconds or more, start the engine again.

4. For 10 minutes, carry out the idling under the condition shown below and then confirm the engine idles normally.

- Transaxle: Neutral (P range on vehicles with TC-SST)
- Operation in ignition-related, fan and attachments: Not to be operated
- Engine coolant temperature: 80°C (176°F) or more

NOTE:
If the engine stalls while idling, check for a dirty (on the throttle valve) of the throttle body and clean if needed. Then perform the service from Procedure 1 again.

INITIALIZATION PROCEDURE FOR THROTTLE ACTUATOR CONTROL MOTOR

When the battery cable is disconnected and reconnected, throttle actuator control motor valve (Fully closed position) is eliminated, so that the throttle valve opening angle control would not be performed correctly. When the battery cable is disconnected and reconnected, initialize the throttle actuator control motor using the following procedure.

1. Turn the ignition switch to the "ON" position then, turn the ignition switch to "LOCK" (OFF) position.

2. For 10 seconds or more, keep the ignition switch in "LOCK" (OFF) position.
