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.
