3.Set the timing light to
the power supply line (terminal No.1) of the ignition coil
No.1.
note |
The power supply line is
looped and also longer than the other
ones.
|
4.Start the engine and let it run at
idle. 5.Use the M.U.T.-III to measure engine idle
speed and check that it is within the standard
value. Standard value: 700 ± 100
r/min 6.Select No. 17 of the M.U.T.-III
Actuator test. 7.Check that basic ignition timing
is within the standard value. Standard value:
5° BTDC ± 3° 8.If the
basic ignition timing is outside the standard value, inspect
the MPI system
(Refer to GROUP 13A - Troubleshooting -
Inspection Chart for Diagnosis Code <Except
for Hong Kong and Singapore> or GROUP
13B - Troubleshooting - Inspection
Chart for Diagnosis Code <Vehicles for Hong Kong and
Singapore> ).

If the test is not cancelled,
a forced driving will continue for
27 minutes. Driving under this condition may
damage the engine.
|
9.Press the M.U.T.-III clear key (Select a
forced driving cancel mode) to release the Actuator
test. 10.Check that ignition timing is at the
standard value. Standard value: approximately
10° BTDC
note |
- The ignition timing may fluctuate within
± 7° BTDC. This is
normal.
- In higher altitude, the ignition timing
is more advanced than the standard value
by approximately 5°.

11.Remove the timing light. 12.Turn
the ignition switch to the "LOCK" (OFF) position and then
