Timing Check
NOTE:
If engine will not start, go to TEST A - NO START . If engine starts but stalls while testing, go to DIAGNOSIS BY SYMPTOM TEST.
- Turn ignition key off, and then wait 10 seconds. Verify that SELF-TEST has been activated. Restart engine and check timing while in SELF-TEST mode. You are allowed 2 minutes to check timing from the time the last code is displayed.
- Correct SELF-TEST timing equals base ignition timing (10° BTDC on all engines) plus 17-23° BTDC. If timing is not 27-33° BTDC, go to TEST MM - SPARK TIMING CHECK . If timing is 27-33° BTDC, go to KEY ON/ENGINE RUNNING (KOER) SELF-TEST .
