Instrument Panel, Gauges and Warning Indicators: Testing and Inspection

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)
- The communication line check (the coolant temperature signal line between the gauge and ECM/PCM)

Entering the self-diagnosis function:
Before doing the self-diagnosis function, check the No.9 (7.5 A) fuse in the under-hood fuse/relay box and No.10 (7.5 A) 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. With in 5 sec., turn the lighting switch OFF, then ON and OFF again.
5. With in 5 sec., release the trip/reset button, then push and release the button four times repeatedly.

NOTE:
- While in the self-diagnosis mode, the dash lights brightness controller operate 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 about 1.2 mph (2 km/h) 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 and sequential sportshift mode segments blink.
The following indicators blink:

Seat belt indicator light, Door/hatch indicator light, Brake system light, Charging system light, Low fuel indicator light,

Maintenance required indicator light (USA), Washer fluid level indicator light (Canada).

A/T gear position Indicator (except [P],[R],[N]) and sequential sportshift mode segments

The LCD Segment Check:

When entering the self-diagnosis mode, the odo/trip segment blinks five times.

The Gauge Drive Circuit Check:




When entering the self-diagnosis mode, the speedometer, the tachometer, the fuel gauge, and the coolant temperature gauge needles 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 until the gauge needles return the minimum position.

The Communication Line Check:




In the self-diagnosis mode, and after the odo/trip LCD Segments Check, the self-diagnosis starts the Communication Line Check.

If all segments comes on, the communication line is OK.

If the word "Error" is indicated, there is a malfunction in the communication line between the gauge assembly, the multiplex control unit, and the ECM/PCM.

Ending the self-diagnosis function:
Turn the ignition switch OFF.

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