2. Check that the electrical connectors of the relevant components are connected securely and the
fuse is not blown.
3. Perform the troubleshooting as follows; first understand the items to be inspected and the the procedures
comprehensively using Trouble Symptom/Failed Component Cross-Reference Table and then inspect
the appropriate items sequentially.
4. Be sure to perform each component check after disconnecting the relevant connector.

IDLE-UP OPERATION CHECK
1. Before inspection and adjustment, set vehicle in the
pre-inspection condition:
2. Check whether or not the idle speed is the standard value.
Standard value: 700 ± 50 r/min
NOTE
There is no necessity to make an adjustment, because
the idle speed is automatically adjusted by the ISC system.
If, however, there occurs a deviation from the standard
value for some reason, check the fuel control system.
3. When the A/C is running after turning the A/C switch
to ON, check to be sure that the idle speed is at the
standard value.
