Combination Meter Self-DiagnosisNJEL0447PERFORMING SELF-DIAGNOSIS MODENJEL0447S011. Turn the ignition switch to the “LOCK” position.
2. Press both reset buttons on the combination meter and keep
them depressed.
3. Turn the ignition switch to the “ON” position, while keeping the
reset buttons pressed.
4. Release both reset buttons then self-diagnosis will start. The
sequence (A to J) 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.

(The meter/gauges operate MIN.,MAX., MAX.,MIN.)
The odo trip meter segment flushes during the sweep
movement.

Check items Display Remarks
H)Error 1
(Bit 0 - Bit 3)
SEL441X
The segment of each bit displays “0”, meaning no failure.
If the bit(s) displays figures other than “0”, the item of the
bit has failed.
For details, refer to “Failure chart for Error 1 and Error E”
below.
I)Error E
(Bit 4 - Bit 7)
SEL442X
J) Fuel warning lamp test
SEL443X
Fuel warning lamp is on and odo trip meter segment
“FUEL” flashes.

When no signal is detected for a few seconds 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
