Idle-up Speed Control Inspection

NOTE:
  • The idle speed cannot be adjusted.
  • The M-MDS is required to verify the idle speed.
  1. Complete the engine tune-up preparation. (See ENGINE TUNE-UP PREPARATION .)
  2. Verify that the idle speed according to each load (M-MDS PID: RPM) is within the specification using the PID/data monitor function of the M-MDS (except idle speed decrease after applying load). (See PCM INSPECTION .)
    • If the engine speed is not within the specification when a specified load is applied, inspect the related input parts, wiring harnesses, and connectors.

    Idle-up speed (MTX: Neutral position, ATX: P position or N position) 

    A/C on: 700-800 RPM
