1. METER GAUGE AND WARNING/INDICATOR GAUGE: GAUGE SPECIFICATIONS Item Detail Speedometer Vehicle speed sensor (Direct line). Tachometer ECM transmits engine speed to the meter to display. ODO/TRIP Meter Combination meter assy. Fuel Displays a fuel level according to a signal from the fuel sender gauge (Direct line). Water Temperature Displays engine coolant temperature according to a signal from the ECM (BEAN). Oil Pressure Receives a signal from the oil pressure sender (Direct line). Volt Meter Displays vehicle voltage according to a voltage from the IG terminal (Direct line). WARNING/INDICATOR: HINT: Combination meter bulb check is performed for 3 seconds after the ignition switch is turned ON. BUZZER: BUZZER SPECIFICATIONS Item Detail Key Reminder Buzzer is ON: Ignition switch is OFF, key is inserted, and door is open. Fasten Belt Buzzer is ON: Ignition switch is ON and seat belt is unfastened.
2. COMBINATION METER IN SEQUOIA HAS THE FOLLOWING FEATURES: Built-in buzzer for the reminder system (key and seat belt) Integrated trip and odometer knobs Press and release knob to scroll through trip "A", trip "B", and odometer features. Press and hold the trip knob to reset trip meter functions. Oil maintenance indicator When 4,500 miles have been traveled, after the ODO/TRIP switch is set, the maintenance indicator begins to blink for 15 seconds after the ignition switch is turned to the ON position. When 5,000 miles have been traveled, after the ODO/TRIP switch is set, the maintenance indicator comes on. Press and hold the trip knob to reset the oil maintenance indicator. Rotate knob to adjust interior illumination

CUSTOMIZE PARAMETERS

HINT

The following can be customized.

Note. After confirming whether the items of the customer's request are applicable or not as customized items, perform customization. Be sure to record the current value before customizing. When troubleshooting, pay attention as there is a possibility that the function has been set to SMALL through customizing (Example: In case of the symptom in which "The key reminder buzzer operation does not function" is displayed, check that the key reminder buzzer operation is not set to SMALL, then perform troubleshooting).

DATA LIST

According to the DATA LIST displayed by the hand-held tester, you can read the values of the switches, sensors, actuators and so on without part removal. Reading the DATA LIST as the first step of troubleshooting is one method to shorten labor time.

1. Warm up the engine.
2. Turn the ignition switch off.
3. Connect the hand-held tester to the DLC3.
4. Turn the ignition switch to the ON position.
5. Operate the hand-held tester according to the steps on the display and select "DATA LIST".
