Idle-Up Operation Check

1. Before inspection and adjustment, set vehicle in the following condition:
- Engine coolant temperature: 80 - 90 °C (176.0 - 194.0 °F)
- Lights, 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 idling speed is the standard value.

Standard value:
<2.4L engine> 750 ± 100 r/min
<3.0L engine> 700 ± 100 r/min

NOTE: Check after 4 minutes since the start of idle operation.

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.
Refer to On-vehicle Service

Standard value: 850 ± 100 r/min

NOTE: The engine control module /the powertrain control module determine whether the load by A/C is low or high according to the output signal from the automatic compressor controller.

NOTE: There is no necessity to make an adjustment, because the idling speed is automatically adjusted by the ISC system. If, however there occurs a deviation from the standard value for some reason, check the ISC system.

NOTE: Check after 4 minutes since the start of idle operation.
