3. OUTLINE OF DIAGNOSIS

Model without push button start

Detect abnormal continuity in the starter SW1.

Judge as OFF NG when the starter SW 1 signal remains OFF.

Model with push button start

Detect abnormal continuity in the starter SW 2.

Judge as OFF NG when the starter SW 2 signal remains OFF.

4. EXECUTION CONDITION

Secondary Parameters

Execution condition

Battery voltage

≥ 8 V

Engine speed

Increase from 0 rpm to 500 rpm or more

Vehicle speed
