2. Check that the idle speed corresponds to the nominal value (see section "Checking the idle speed").
3. Set the air conditioner switch to "ON" (A/C ON), the heater fan switch to position "MN" or "HI". Make sure the idle speed is within the rated value with the A/C running.
Rated value:
- Engine 2.4L:
- "A/C OFF" — 700±100 rpm
- "A/C ON" — 850±100 rpm
- Engine 2.7L:
- "A/C OFF" — 700±100 rpm
- "A/C ON" — 870±100 rpm
Note: The amount of increased idle speed is set by the engine management system depending on the signal from the air conditioning electronic control unit.
4. In case of discrepancy between the value of the increased idle speed and the nominal value, check the components of the fuel injection system (see the relevant section of the chapter "fuel injection system (MFI)").
