Electrical system
•
Example value with key ON: 3560 mV
•
Example value with engine on: -
Voltage value of the rear potentiometer track C
White rear connector throttle grip position sensor - track D
•
Example value with key ON: 3555 mV
•
Example value with engine on: -
Voltage value times 2 of the rear potentiometer track D
Throttle grip position sensor
•
Example value with key ON: 1107 mV
•
Example value with engine on: -
Voltage corresponding to the potentiometer track A
Throttle grip opening percentage
•
Example value with key ON: 0 mV
•
Example value with engine on: -
With a released throttle grip, the value read should be 0%, whereas 100 % should be read with throttle
grip fully twisted.

CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING, CAREFULLY READ THE GENERAL TROU-
BLESHOOTING CONCEPTS FOR ELECTRICAL DEVICES AT THE BEGINNING OF THE CHECK
AND CONTROL SECTION IN THE ELECTRICAL SYSTEM CHAPTER.
DIAGNOSTICS INSTRUMENT: ELECTRICAL ERRORS
Blue front connector throttle grip position sensor - track A P0150
•
short circuit to positive / open circuit, short circuit to negative
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 39 of the ENGINE con-
nector. If the circuit is open, shorted to negative: voltage equal to zero has been detected
at PIN 39 of the ENGINE connector.
Troubleshooting
•
shorted to positive: check the value shown by the parameter of the BLUE front connector
Throttle Grip Position Sensor - track A: disconnect the connector and read the value indi-
