Ignition Timing: Testing and Inspection
Ignition Timing Inspection
Note:
^ The ignition timing cannot be adjusted.
^ The M-MDS is required to verify the ignition timing.
1. Complete the engine tune-up preparation. (See Engine Tune-up Preparation.) Testing and Inspection
2. Connect the timing light to the front rotor housing on the leading side.
3. Turn the test mode on using the test simulation function.
4. Verify that the eccentric shaft position plate alignment mark (white) and the front cover mark (white) is aligned.
Note: When using the M-MDS, verify that the ignition timing (M-MDS: SPARK-T or SPARK-L PID) is as follows:
Ignition timing
Trailing side: BTDC 10°
Leading side: BTDC -5°
^ If there is malfunction, refer to "ENGINE SYMPTOM TROUBLESHOOTING".
5. Turn the test mode off using the test simulation function.
