W/L ON HISTORY

• Stores histories when warning/indicator lamp is turned on.

• “W/L ON HISTORY” indicates the “TIME” when the warning/indicator lamp is turned on.

• The “TIME” above is:

- 0: The condition that the warning/indicator lamp has been turned on 1 or more times after starting the engine

and waiting for 30 seconds.

- 1 - 39: The number of times the engine was restarted after the 0 condition.

- NO W/L ON HISTORY: Stores NO (0) turning on history of warning/indicator lamp.
