2. Turn the ignition switch to the "LOCK" (OFF)
position and then connect the M.U.T.-III to the
diagnosis connector.
No.1 Ignition coil
3. Set the timing light to the terminal No. 3 power
supply line (white) of the ignition coil No. 1.
4. Start the engine and let it run at idle.
5. Check that ignition timing is at the standard value.
Standard value: approximately 10° BTDC
NOTE: .
•
The ignition timing may fluctuate within
This is normal.
•
In higher altitude, the ignition timing is more
advanced than the standard value by approxi-

mately 5 .
•
Wait till approximately 1 minute passes after
the engine started, and check the ignition tim-
ing when the engine stabilized.
6. Run the engine at 2,000 − 3,000 r/min for 2
minutes.
7. Set the CO, HC tester.
8. Check the CO contents and the HC contents at
idle.
Standard value
CO contents: 0.3% or less
HC contents: 200 ppm or less
9. If there is a deviation from the standard value,
inspect the MPI system (Refer to WORKSHOP
MANUAL GROUP 13 − Troubleshooting).
10.Remove the timing light.
11.Turn the ignition switch to the "LOCK" (OFF)

CHECK ON OPERATING SOUND
Carry out this check after checking that the diagnosis
code is not stored. If the diagnosis code is stored, the
EGR valve (DC motor) could possibly not be
