Idle Speed Inspection

NOTE: Before checking the idle speed, check these items:

1.Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.


2.Start the engine. Hold the engine speed at 3,000 rpm (min-1) without load (in neutral) until the radiator fan comes on, then let it idle.

3.Check the idle speed without load conditions: headlights, blower fan, radiator fan, and air conditioner off.

Idle speed should be: 850±50 rpm (min-1) 

NOTE: If the idle speed is not within specification, go to the symptom troubleshooting.
