SPECIAL FUNCTION
Special menu
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.
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.
Display Item
FUEL LOW SIG
[On/Off] Status of fuel level low warning signal to output to AV control unit via CAN com-
munication.
TOW MODE IND
[On/Off] Status of TOW mode indicator lamp judged from TOW mode indicator lamp signal
received from TCM with CAN communication line.
BUZZER
[On/Off] XBuzzer status (in the combination meter) is detected from the buzzer output signal
received from each unit via CAN communication and the warning output condition
of the combination meter.
