On-Vehicle Inspection

  1. CHECK THROTTLE BODY ASSEMBLY 
    NOTE: Always perform the inspection after installing the throttle body or removing/installing other components.
    1. Remove the EFI MAIN and ETCS fuses at the same time and then reconnect them after waiting 60 seconds or more.
    2. Install the throttle body, and then turn the power switch ON (IG) without operating the accelerator pedal.
      NOTE: If the accelerator pedal is operated, begin the procedure again from the beginning.
    3. Inspect engine idle speed (see ON-VEHICLE INSPECTION )
