Idle-Up Operation Check

IDLE-UP OPERATION CHECK

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

1. Check whether or not the idle speed is the standard value.
Refer to Engine mechanical On-vehicle Service - Idle Speed Check. <2400>
Refer to Engine mechanical On-vehicle Service - Idle Speed Check <3000>

Standard value: 650 ± 50 r/min

2. Turn on the A/C switch and the blower speed selection dial. Engine idling speed should be within the standard value:

Standard value: 8000 ± 50 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.
- 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 or some reason, check the ISC system. (Refer to Engine mechanical On-vehicle Service - Idle Speed Check <2400> or Engine mechanical On-vehicle Service -Idle Speed Check <3000>)
