Ignition Timing: Testing and Inspection

Ignition Timing Inspection

Note:
^ Ignition timing is not adjustable.
^ Ignition timing verification requires M-MDS.

1. Verify that the ignition timing (M-MDS: SPARKADV PID) is within the specification using M-MDS.

Ignition timing
Approximately BTDC 8°

2. Verify that ignition timing advances when the engine speed increases gradually.
