- when the starter switch is held down for more than 4 seconds, causing the warning
light to flash
- when the ignition circuit cut-off system stops the engine or prevents it from starting
** This condition code is also displayed when the engine is operated at 5,000 r/min for at
least 30 seconds with the rear wheel at standstill.
*** This condition code is also displayed when the engine stop switch is turned to “ ”
while riding with the transmission in gear. Condition

11 Camshaft sensor • No incoming sig-
nalThe ECU pairs the ignition of cyl-
inders #1 and #4 and cylinders #2
and #3. The motorcycle can be
ridden.
12* Pickup coil • No incoming sig-
nalThe motorcycle cannot be ridden.
13 Intake air pressure
sensor• Disconnected
• Short-circuitThe ECU stays set to an intake air
pressure of 760 mm Hg (29.9 in Hg).
The motorcycle can be ridden.
14 Intake air pressure
sensor hose and
negative pressure
hose• Improper connec-
tion
• Bending
15 Throttle position
sensor• Disconnected
• Short-circuitThe ECU stays set to a wide throt-
tle opening.
The motorcycle can be ridden.
16 Throttle position
sensor• Locked
21 Coolant tempera-
ture sensor• Disconnected
• Short-circuitThe ECU stays set to a coolant
temperature of 80˚C (176˚F).

ture sensor• Disconnected
• Short-circuitThe ECU stays set to an intake air
temperature of 40˚C (104˚F).
The motorcycle can be ridden.
23 Atmospheric pres-
sure sensor• Disconnected
• Short-circuitThe ECU stays set to an atmo-
spheric pressure of 760 mm Hg
(29.9 in Hg).
The motorcycle can be ridden.
41 Fall detection
switch• Disconnected The main relay stays switched off.
The motorcycle cannot be ridden.
42** Speed sensor • Incorrect signal The ECU stays set to 6th gear.
