SELF-DIAGNOSIS FUNCTION

The following items can be checked during Combination Meter Self-Diagnosis Mode.

  1. Gauge sweep and present gauge values.
  2. Illuminates all odometer/trip meters and A/T indicator segments.
  3. Illuminates all micro controlled lamps/LEDs regardless of switch position.
  4. Displays estimated present battery voltage.
  5. Displays seat belt buckle switch LH status.

HOW TO INITIATE COMBINATION METER SELF-DIAGNOSIS MODE

Note. Once entered, Combination Meter Self-Diagnosis Mode will function with the ignition switch in ON or START. Combination Meter Self-Diagnosis Mode will exit upon turning the ignition switch to OFF or ACC.

To initiate Combination Meter Self-Diagnosis Mode, refer to the following procedure.

  1. Turn the ignition switch ON, while pressing the odometer/trip meter switch for 5-8 seconds. When the diagnosis function is activated the odometer/trip meter will display tESt. NOTE: Check combination meter power supply and ground circuit when self-diagnosis mode of combination meter does not start. Refer to " «POWER SUPPLY AND GROUND CIRCUIT INSPECTION»(ref-272357-S06239046642007111800000) ". Replace combination meter if normal. Refer to " «COMBINATION METER»(ref-272364-S06033080672007111800000) ".
