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 then self-diagnosis will start. The
sequence (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.

Failure No failure
0Speedometer input
signalNo input signal
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
0
Abnormal input signal
When any signal of frequency which would not exist in normal
conditions is detected, it should be judged as signal failure.2

When short circuit of the signal line is detected for 5 seconds
or more, it should be judged as short-circuit failure.1
