Combination Meter Self-Diagnosis
PERFORMING SELF-DIAGNOSIS MODE
1. Turn the ignition switch to the ªLOCKº position.
2. Press both reset buttons on the combination meter and keep them depressed.
3. Turn the ignition switch to the ªONº position, while keeping the reset buttons pressed.
4. Release both reset buttons within 5 seconds after ignition switch is ªONº, then self-diagnosis will start. Thesequence (A to I) is activated by press the either reset buttons.
NOTE:
If either reset button is not pressed for 20 seconds at each step or if the ignition switch is turned OFF, the
self-diagnosis mode is exited.

F) Meter/gauge test
(Sweeping movement)
SEL440X
Tachometer, speedometer, fuel level gauge and water tem-
perature gauge have sweeping movement test.
(The meter/gauges operate MIN.
,MAX., MAX. ,MIN. for
2 times)
The odo trip meter segment flashes during the sweep move-
ment.
G) Error 1
(Bit 0 - Bit 3)
SEL441X
The segment of each bit displays ª0º, meaning no failure. If
the bit(s) displays figures other than ª0º, the item of the bit
has failed.
For details, refer to ªFailure chart for Error 1 and Error Eº
below.

SymptomPossible causes Repair order
Odo/trip meter indicates
malfunction in Diagnosis
mode. Unified meter control unit
Replace unified meter control unit.
Multiple meter/gauge indi-
cate malfunction in Diagno-
sis mode.
One of speedometer/
tachometer/fuel gauge/
water temp. gauge indicates
malfunction in Diagnosis
mode. 1. Meter/Gauge
2. Unified meter control unit
1. Check resistance of meter/gauge indicating malfunction.
If the resistance is NG, replace the meter/gauge.
2. If the resistance of meter/gauge is OK, replace unified- meter control unit.
Symptom Chart 2 (No Malfunction is Indicated in Diagnosis Mode)
Symptom Possible causes Repair order
One of speedometer/
tachometer/fuel gauge/
water temp. gauge is mal-
functioning. 1. Sensor signal
- Vehicle speed signal
- Engine revolution signal
- Fuel gauge
- Water temp. gauge
2. Unified meter control unit 1. Check the sensor for malfunctioning meter/gauge.
