POSSIBLE FAULT
Faulty solenoid - faulty terminal at
solenoid or at engine connector
- Dirt stuck on solenoid blades
and/or terminals - wires from the
ECM to the solenoid shorted to
a power source
Damaged encoder wheel -
damaged CPS - metal dirt stuck
on CPS - CPS wires damaged
and/or shorted to the engine
or frame - squeezed CPS wires
between the magneto cover and
engine
Damaged encoder wheel -
damaged CPS - metal dirt stuck
on CPS - CPS wires damaged
and/or shorted to the engine
or frame - squeezed CPS wires
between the magneto cover and
engine
Damaged encoder wheel -
damaged CPS - metal dirt stuck
on CPS - CPS wires damaged
and/or shorted to the engine
or frame - squeezed CPS wires
between the magneto cover and
engine
Faulty primary ignition coil - wire
shorted to battery 12 V
Faulty relay - faulty terminal under
the relay or at engine connector -
Dirt stuck on relay blades and/or
terminals - wires from the ECM
to the relay cut
Faulty relay - faulty terminal under
the relay or at engine connector -
Dirt stuck on relay blades and/or
terminals - wires from the ECM
to the relay shorted to a power
source
Faulty relay - faulty terminal
under the relay or at engine
connector - Dirt or water stuck
on relay blades and/or terminals -
wires from the ECM to the relay
shorted to a GND
Faulty IACV - disconnected
connector - faulty terminals - cut
wires - shorted wire
ACTION
Check for damaged or disconnected
starter solenoid, damaged circuit wires,
damaged connectors or damaged ECM
output pins. Check circuit from solenoid
ORANGE/BROWN wire to ECM pin L3.
Check circuit between CPS and ECM
pin E1 and D1. Check CPS coil resistor
value approx. 260 ohm. Check CPS AC
voltage value approx. 0,95 V. Check CPS
wires. Check if CPS is dirty with metal
particle. Check encoder wheel.
Check circuit between CPS and ECM
pin E1 and D1. Check CPS coil resistor
value approx. 260 ohm. Check CPS AC
voltage value approx. 0,95 V. Check CPS
wires. Check if CPS is dirty with metal
particle. Check encoder wheel.
Check circuit between CPS and ECM
pin E1 and D1. Check CPS resistor value
approx. 260 ohm. Check CPS AC voltage
value approx. 0,95 V. Check CPS wires.
Check if CPS is dirty with metal particle.
Check encoder wheel.
Check for 1 +/-0.5 ohm between ignition
coil pins. Check circuit between ignition
coil (-) and ECM pin M1 and M2 if shorted
to 12 V.
Check cooling fan and acc. fuse. Look
for damaged or disconnected cooling fan
relay, damaged connectors or damaged
ECM output pins. Check circuit from relay
pin 1 to ECM pin B3. Check circuit from
relay pin 1 to cooling fan and acc. fuse.
Check cooling fan and acc. fuse. Check
for damaged or disconnected cooling fan
relay, damaged circuit wires, damaged
connectors or damaged ECM output pins.
Check circuit from relay pin 1 to ECM
pin B3.
Check for damaged or disconnected
cooling fan relay, damaged circuit wires,
damaged connectors or damaged ECM
output pins. Check circuit from relay pin 1
to ECM pin B3.
Make sure IACV connector is fully inserted.
Check circuits between idle valve motor
pins and ECM pins D3-1, E4-2, C4-3 and
D4-4.
