BASIC IDLE SPEED ADJUSTMENTMlIFHBX
NOTE
1. The standard idling speed has been adjusted, by the en-
gine speed adjusting screw, by the manufacturer, and
there should usually be no need for readjustment.
2. Use the following procedure to adjust when the idling speed drops due to an incorrect adjustment, high idling
speed, or when a load such as the air conditioning is ap-
plied on the engine.
3. The adjustment, if made, should be made after first con- firming that the spark plugs, the injectors, the idle air con-
trol motor, the compression pressure, etc. are all normal.
(I ) The vehicle should be prepared as follows before the inspec- tion and adjustment.
l Engine coolant temperature:
85-95°C (185-203°F)
l Lights, cooling fan and accessories: OFF
l Transaxle: neutral (A/T for
P range)
l Steering wheel: neutral position
(2) Connect the scan tool to the data link connector (white).
NOTE
When the scan tool is connected, the diagnostic test mode control terminal should be grounded.
(3) If the scan tool is not used, follow the steps below.
@I Insert a paper clip into the l-pin connector (blue) shown in the figure at the left.
0 Connect a primary-voltage-detection type of tacho-meter to the paper clip.
