1. Before inspection and adjustment, set vehicle in
the following condition:
•Engine coolant temperature: 80 − 90 °C•Lamps, electric cooling fan and accessories: Set
to OFF
•Transmission: Neutral ("N" or "P" for vehicles with
A/T)
•Steering wheel: Straightforward
2. Check whether or not the idle speed is the
standard value. <1300, 1600> Refer to GROUP
13A, On-vehicle Service − Basic Idle Speed
Adjustment P.13A-387.
<2000> Refer to GROUP 13B, On-vehicle Service
− Basic Idle Speed Adjustment P.13B-324.
Standard value: 750 ± 50 r/min
3. When the A/C is running after turning the A/C
switch to ON, and the blower switch to the 3(MH)
or 4(HI) position, check to be sure that the idle
speed is at the standard value.
Standard value: 850 ± 50 r/min
NOTE: It is not necessary to make an adjustment,
because the idling speed is automatically
adjusted by the ISC system. If, however, a
deviation from the standard value occurs for some
reason, check the ISC system.
