The gauge assembly has a self-diagnostic 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)

Before doing the self-diagnostic 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, then check for ECM/PCM DTC(s). Troubleshoot and repair the cause of
the DTC(s) first.

1. Push and hold the trip/reset button.

2. Turn the lighting switch ON.

3. Turn the ignition switch ON (II).

4. Within 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-diagnostic mode, the dash lights brightness controller operates normally.
• While in the self-diagnostic 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 1.2 mph (2 km/h) or the ignition switch is turned OFF, the self-diagnostic mode ends.

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

When entering the self-diagnostic mode, the following indicators and sequential sportshift mode segments blink.
Seat belt indicator, Door/hatch indicator, Brake system light, Charging system light, Low fuel indicator, Maintenance
required indicator (USA), Washer fluid level indicator (Canada),
A/T gear position indicator (except P, R, N) and sequential sportshift mode segments.

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

When entering the self-diagnostic mode, the speedometer, the tachometer, the fuel gauge, and the coolant
temperature gauge needles move 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 to the minimum position.

In the self-diagnostic mode, after the odo/trip LCD segments check, the self-diagnostic starts the communication line
check.
If all segments come 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, the keyless control unit, and the ECM/PCM.

Turn the ignition switch OFF.
NOTE: If the vehicle speed exceeds 1.2 mph (2 km/h), the self-diagnostic function ends.
If any of the checks do not function as specified, replace the gauge assembly.

The needles sweep from the
minimum position to the
maximum position, then return
to the minimum position.
