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.

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.
