Diagnosis Description

INFOID:0000000001702262

SELF-DIAGNOSIS MODE

The following items can be checked during Combination Meter Self-Diagnosis Mode.
• Gauge sweep and present gauge values.
• Illuminates all odometer/trip meters and A/T indicator segments.
• Illuminates all micro controlled lamps/LEDs regardless of switch position.
• Displays estimated present battery voltage.
• Displays seat belt buckle switch LH status.

OPERATION PROCEDURE

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.

• If the diagnosis function is activated with trip A displayed, the mileage on trip A is reset to 0000.0. (Trip B

operates the same way.)

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

MWI-29, "COMBINATION METER : Diagnosis Procedure"

. Replace combination

meter if normal. Refer to

MWI-94, "Removal and Installation"

.
