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.
