FUEL INJECTION SYSTEM
Sensor operation data display verification table
NOTE:
• Check the intake temperature and coolant temperature as close as possible to the area in which
the respective sensor is mounted.
• If it is not possible to check it with an atmospheric pressure gauge, judge it by using 760 mm Hg
(29.92 in Hg) as the standard.
• If it is not possible to check the intake temperature, use the ambient temperature as reference
(use the compared values for reference).
Diag code Item Description of action
Data displayed on meter
(reference value)
01
Throttle angle Displays the throttle angle.
• Check with throttle fully closed.
• Check with throttle fully open. 0 ~ 125 degrees
• Fully closed position (15 ~ 17)
• Fully open position (97 ~ 100)
02
Atmospheric pres-
sure Displays the atmospheric pressure.
* Use an atmospheric pressure gauge to check the atmo-
spheric pressure.
Compare it to the value dis-
played on the meter.
03
Pressure difference
(atmospheric pres-
sure - intake air pres-
sure) Displays the pressure difference (atmospheric pressure -
intake air pressure).
Engine stop switch is on.
* Generate the pressure difference by cranking the engine
with the starter, without actually starting the engine.
10 ~ 200 mm Hg
(0.39 ~ 7.87 in Hg)
05
Intake temperature Displays the intake air temperature.
* Check the temperature in the air cleaner case. Compare it to the value dis-
played on the meter.
06
Coolant temperature Displays the coolant temperature.
* Check the temperature of the coolant. Compare it to the value dis-
played on the meter.
07
Vehicle speed pulse Displays the accumulation of the vehicle pulses that are gen-
erated when the tire is spun. (0 ~ 999; resets to 0 after 999)
OK if the numbers appear on
the meter.
08
Lean angle cut-off
switch Displays the lean angle cut-off switch values. Upright: 0.4 ~ 1.4 V
Overturned: 3.8 ~ 4.2 V
09
Fuel system voltage
(battery voltage) Displays the fuel system voltage (battery voltage).
Engine stop switch is on. 0 ~ 18.7 V
Normally, approximately 12.0 V
20
Sidestand switch Displays that the switch is ON or OFF. (When the gear is in a
position other than neutral.) Stand retracted: ON
Stand extended: OFF
21
Neutral switch Displays that the switch is ON or OFF. Neutral: ON
In gear: OFF
60
E2PROM fault code
display • Transmits the abnormal portion of the data in the E2PROM
that has been detected as a self-diagnostic fault code 44.
• If multiple malfunctions have been detected, different codes
are displayed at 2-second intervals, and this process is
repeated.
(01 ~ 04) Displays the cylinder
number.
(00) Displays when there is no
malfunction.
61
Malfunction history
code display • Displays the codes of the history of the self-diagnosis mal-
functions (i.e., a code of a malfunction that occurred once
and which has been corrected).
• If multiple malfunctions have been detected, different codes
are displayed at 2-second intervals, and this process is
repeated.
11 ~ 50
(00) Displays when there is no
malfunction.
62
Malfunction history
code erasure • Displays the total number of codes that are being detected
through self diagnosis and the fault codes in the past his-
tory.
• Erases only the history codes when the engine stop switch
is turned from OFF to ON. If the engine stop switch is ON,
turn it OFF once, and then turn it back ON.
00 ~ 21
(00) Displays when there is no
malfunction.
70 Control number • Displays the program control number. 00 ~ 255
