Idle-Up Operation Check

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: OFF
- Transmission: Neutral ("N" or "P" position)
- Steering wheel: Straightforward

2. Check whether or not the idle speed is the standard value.

Standard value: 680 ±100 r/min

3. Turn on the air conditioning switch and the blower speed selection dial. Engine idling speed should be within the standard value:

Standard value
At low pressure: 680 ±100 r/min
At middle pressure: 730 ±100 r/min
At high pressure: 750 ±100 r/min

NOTE: The powertrain control module determines whether the A/C load is low or high according to the output signal from the A/C-ECU.

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.
