PREPARATION
1. Warm up the engine to normal operating temperature.
2. Shift the selector lever to P range.
3. Turn off all electric loads.
- Headlight
- Blower
- Rear window defroster
- Power steering
4. Wait until the coolant fan is stopped.

Note: If the climate control panel is in DEFROSTER mode, the A/C compressor will be on. Do not set this mode during ignition timing and idle speed adjustment or self-diagnosis start-up.

IDLE SPEED CHECK
1. Perform Preparation.
2. Connect the SST to the data link connector.
3. Verify that the idle speed is within specification using the SST.
(1) Activate the Key On Engine Running self-diagnosis inspection.
(2) After DTC slow code output is completed, unlatch and within 4 sec. latch the "HOLD TEST" button.
(3) A single pulse indicates the entry mode. Then, observe the STO (self-test output) of the SST in the following.
(A) A constant tone or STO LO readout means idle speed is within specification.
(B) A beeping tone or STO LO readout at (8 Hz) indicates that the throttle position sensor is out of range. Adjust the throttle position sensor.

Note: Idle speed adjustment may be necessary after throttle position sensor adjustment.

(C) A beeping tone or STO LO readout at (4 Hz) indicates the idle speed is too fast.
(D) A beeping tone or STO LO readout at (1 Hz) indicates the idle speed is too slow.




4. If not within the specification. Remove the shorting bar from the double wire SPOUT connector.
