WARNING: This page is about a different variant/trim than selected.

Air fuel ratio initial learning of ECM to learn the air fuel ratio that keeps each engine idle speed within the specific range. It must be performed under any of the following conditions:

When ECM is replaced ^*
When engine assembly is replaced ^*
When electric throttle control actuator is replaced ^*
When mass air flow sensor is replaced
When fuel injector is replaced

Refer to Work Procedure .

CAUTION: *: Must be performed "IDLE AIR VOLUME LEARNING" when electric throttle control actuator or ECM is replaced. Refer to Description .
