WARNING HISTORY
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 engi ne was restarted after the 0 condition.
- NO W/L ON HISTORY: Stores NO (0) turning on history of warning/indicator lamp.
NOTE:
• W/L ON HISTORY is not stored for approximately 30 seconds after the engine starts.
• Brake warning lamp does not store any history when the parking brake is applied or the brake fluid level gets
low.

4. Check voltage between ambient sensor harness connector and ground.
Is the inspection result normal?
YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK AMBIENT SENSOR POWER SUPPLY FOR OPEN OR SHORT
1. Turn ignition switch OFF.
2. Disconnect combination meter connec tor and ambient sensor connector.
3. Check continuity between combination meter harness connector and ambient sensor harness connector.
4. Check continuity between combination meter harness connector and ground.
Is the inspection result normal?
YES >> Replace combination meter. Refer to MWI-115, "Removal and Installation".
