Diagnosis code list
Diagnosis
codeInspected item System responseTachometer display
(0 ~ 10,000 r/min)
00 — — —
01 Voltage The tachometer displays the volt-
age ´ 500.
Example:
If the voltage is 12.5 V, the tachome-
ter displays 12.5 ´ 500 = 6,250 r/min.0 r/min (0 V) –
10,000 r/min (20 V)
02 Atmospheric
pressureThe tachometer displays the atmo-
spheric pressure sensor signal.
Example:
If the atmospheric pressure is 760
mm Hg (29.9 in Hg), the tachometer
displays 8,000 r/min.
03 Intake air pres-
sureThe tachometer displays the differ-
ence between the minimum intake
air pressure sensor signal and the
atmospheric pressure sensor signal
after the main switch is turned to
“ON” in the diagnosis mode.0 r/min (0 mm Hg)
– 1,000 r/min
(100 mm Hg)
04 Throttle position
sensorThe tachometer displays the throttle
position sensor signal.1,300 r/min (0.68 V) –
5,900 r/min (2.93 V)
05 Throttle position
sensorThe tachometer displays the mini-
mum throttle position sensor signal.5,500 r/min (0.68 V) –
10,000 r/min (1.25 V)
06 Intake air temper-
atureThe tachometer displays the intake
air temperature signal.4,800 r/min (20˚C) –
5,700 r/min (30˚C)
07 Coolant tempera-
tureThe tachometer displays the coolant
temperature sensor signal.4,900 r/min (20˚C) –
9,200 r/min (100˚C)
08 Speed sensor The tachometer displays the speed
sensor signal when the rear wheel is
rotated by hand.0 –
09 Fall detection
switchThe tachometer displays whether
the fall detection switch is on or
whether it is off or disconnected.0 r/min (on), 8,000 r/
min (off) or 10,000 r/
min (disconnected)
10 Sidestand switch The tachometer displays whether
the sidestand switch is on or off.
The tachometer displays 0 r/min
when the sidestand is down (switch
on) and 10,000 r/min when the side-
stand is up (switch off).0 r/min (on) or
10,000 r/min (off)
