## Gauges Self-diagnostic Procedure

The gauge assembly has a self-diagnosis function.

- The beeper drive circuit check
- The indicator drive circuit check
- The LCD segments check
- The gauges drive circuit check (Speedometer, Tachometer, Fuel gauge, Coolant temperature gauge)

## Entering the self-diagnosis function

Before doing the self-diagnosis function, check the No. 8 (15A) fuse in the under-hood fuse/relay box and the No. 3 ( 7.5A) fuse in the under-dash fuse/relay box.

1. | Push and hold the trip/reset button.

2. | Turn the lighting switch ON.

3. | Turn the ignition switch ON (II).

4. | From 2 sec. to less than 5 sec., turn the lighting switch OFF, then ON and OFF again.

5. | Within 5 sec., release the trip/reset button, then push and release the button three times repeatedly.

NOTE:

- While in the self-diagnosis mode, the dash lights brightness controller operates normally.
- While in the self-diagnosis mode, the trip/reset button is used to start the Beeper Drive Circuit Test and the Gauge Drive Circuit Check.
- If the vehicle speed exceeds 2 km/h (1.2 mph) or the ignition switch is turned OFF, the self-diagnosis mode ends.

## The Beeper Drive Circuit Check

When entering the self-diagnosis mode, the beeper sounds five times.

## The Indicator Drive Circuit Check

When entering the self-diagnosis mode, the indicator lights blink.
The following indicators blink:
Seat belt indicator light, Coolant high temperature warning light, Coolant low temperature warning light, Low fuel indicator light, Brake system light (without ABS).

## Switch Input Check

After the intermittent beeper sounds at the initial stage of self-diagnosis, a beeper sounds continuously while any of the following switch inputs are switched from OFF to ON.
The following switches cause the beeper sounds:
Seat belt switch, Trip/reset switch.

## The LCD Segment Check

When entering the self-diagnosis mode, the odo/trip segments and outside air temperature segment blink five times.

## The Gauge Drive Circuit Check

When entering the self-diagnosis mode, the speedometer, the tachometer, and the fuel gauge needles sweep from the minimum position to maximum position, then return to the minimum position.

NOTE:
After the beeper stops sounding and the gauge needles return to the minimum position, pushing the trip/reset button starts the Beeper Drive Circuit Check (one beep) and the Gauge Drive Circuit Check again.
The check cannot be started again until the gauge needles return to the minimum position.

If a needle fails to sweep or the beeper does not sound, replace the gauge control module.

## Ending the self-diagnosis function

Turn the ignition switch OFF.
NOTE: If the vehicle speed exceeds 2 km/h (1.2 mph), the self-diagnosis function ends.
