Idle-Up Operation Check

Before inspection and adjustment, set vehicle in the following condition:
- Engine coolant temperature: 80 - 90 °C (176 - 194 °F)
- Lights, electric cooling fan and accessories: Set to OFF
- Transmission: "N" or "P" position
- Steering wheel: Straightforward

1. Check whether or not the idling speed is the standard value.

Standard value: 700 ± 100 r/min

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

2. When the A/C is running after turning the A/C switch to ON, and the blower switch to the MH or HI position, check to be sure that the idle speed is at the standard value.




Standard value:

NOTE: It depends on the outside air temperature signal whether a low load, a middle load or a high load is applied to the air conditioning. The PCM receives the signal via the automatic compressor controller and determines whether the air conditioning is working under high, middle or low load.
