intake manifold and the ignition system are changed, the following service adjustment procedures are
made. Otherwise, the procedures are the same as that of the existing models.

IGNITION TIMING CHECK

Set the vehicle to the pre-inspection condition.

After turning the ignition switch to the LOCK (OFF) position,
connect the MUT-II to the diagnosis connector.

Connect a timing light.

Start the engine and run it at idle.

Select item No. 22 on the MUT-II and take a reading of the
engine speed. Check that the idle speed is at the standard
value.

Standard value: 750

100 r/min

Select item No. 17 (actuator test function) on the MUT-II,
and set the ignition timing to the basic ignition timing.

Check the basic ignition timing.

Standard value: 5

BTDC

If the basic ignition timing is outside the standard value
range, check the MPI system while referring to GROUP 13B
– Troubleshooting.

Press the CLEAR key on the MUT-II to cancel the basic
ignition timing setting mode by the actuator test function.

Caution
If the mode is not cancelled, the basic ignition timing
setting mode will remain active for 27 minutes, and
problems with engine operation may result if the
vehicle is driven during this period.
