4. Select the item No.30 of the MUT-
II
Actuator test.
NOTE
This holds the idle speed control servo at the basic step
to adjust the basic idle speed.
5. Check the basic idle speed.
Standard value: 750
±
50 r/min
NOTE
(1) The engine speed may be 20 to 100 r/min lower
than indicated above for a new vehicle [driven
approximately 500 km or less], but no adjustment
is necessary.
(2) If the engine stalls or the engine speed is low even
though the vehicle has been driven approximately
500 km or more, it is probable that deposits are
adhered to the throttle valve, so clean it.
6. If not within the standard value range, turn the speed
adjusting screw (SAS) to make the necessary adjustment.
NOTE
(1) Use a screwdriver which is shorter than 30 mm to
turn the SAS.
(2) If the idling speed is higher than the standard value
range even when the SAS is fully closed, check
whether or not there is any indication that the fixed
SAS has been moved. If there is an indication that
it has been moved, adjust the fixed SAS.
7. Press the MUT-
II
clear key, and release the idle speed
control servo from the Actuator test mode.
NOTE
Unless the idle speed control servo is released, the
Actuator test mode will continue 27 minutes.
