IDLE-UP OPERATION CHECK

M1552001600553

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.
Refer to GROUP 11A, On-vehicle Service

− Basic

Idle Speed Adjustment

P.11A-9

.

Standard value: 700

± 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

± 100 r/min

NOTE: . It is not necessary to make an adjust-
ment, because the idling speed is automatically
adjusted by the ISC system. If, however, a devia-
tion from the standard value occurs for some rea-
son, check the ISC system.
