Combination Meter Self-DiagnosisNJEL0447PERFORMING SELF-DIAGNOSIS MODENJEL0447S011. 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 then self-diagnosis will start. The
sequence (A to L) 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.

G)Meter/gauge test
(Sweeping movement)
SEL440X
Tachometer, speedometer, fuel level gauge and water
temperature gauge have sweeping movement test.
(The meter/gauges operate MIN.®MAX., MAX.®MIN.
for 2 times)
The odo trip meter segment flushes during the sweep
movement.

H)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.

When no signal is detected for 30 minutes continuously
with the ignition ON, it should be judged as signal failure.
(If input signal is detected later, then the judgement will be
canceled immediately.)1

Abnormal input signal
When any signal of frequency which would not exist in nor-
mal conditions is detected, it should be judged as signal
failure.2

Combination Meter Calibration
After replacing a combination meter, it might be necessary to cali-
brate the fuel gauge/low fuel warning lamp. In case the fuel warn-
ing lamp is flashing after replacing the combination meter perform
the following:
1. Press both reset buttons.
2. Turn the ignition ONand keep the reset buttons depressed
for at least 5 seconds.
3. Release both reset buttons.
The low fuel warning lamp will stop flashing and the combina-
tion meter will show CALL and possibly CALL FAIL. Showing
CALL FAIL does not indicate a concern as this might be related
to the current (unexpected) amount of fuel in the tank.
