•
incongruent signal
Error cause
•
Two illogical voltage signals have been detected at PIN 23 and 11 of the ENGINE connector
(tracks A-B)
Troubleshooting
•
Check the parameters of the white upper connector Throttle Grip Position Sensor - tracks
C and D: if one of the two values clearly deviates from 600-1400 mV, it means that this
potentiometer is defective. Check the throttle grip sensor connector and the control unit
connector: if not OK, restore. If OK, check that cable resistance between the throttle grip
sensor connector and the control unit is a few tenths of Ohm: if this is not the case, restore
wiring. If the value is correct, replace the complete throttle grip sensor
Throttle grip position P0156
•
incongruent signal
Error cause
•
The value of the lower side sensor (tracks A-B) does not coincide with the value of the upper
side sensor (tracks C-D)
Troubleshooting
•
Replace the throttle grip sensor
DIAGNOSIS INSTRUMENT: ADJUSTABLE PARAMETERS
Throttle grip self-acquisition: -
RESET PROCEDURE
•
If Marelli control unit or its mapping are replaced or if you carry out control unit EEPROM
zero setting or if you replace the throttle grip sensor, it is necessary to carry out the handle
grip self-acquisition procedure with the diagnosis instrument: once the check is completed,
make sure that the throttle grip Self-acquisition status indicates: carried out
CAUTION
THE TWO CONNECTORS WHICH GET TO THE THROTTLE GRIP SENSOR ARE ALIKE BUT THEY
SHOULD NEVER BE INVERTED. MARK OR CHECK THE CONNECTOR MARKING BEFORE RE-
MOVING THEM (BLUE STAMP + BLUE BAND). THE BLUE CONNECTOR AND COLLAR ARE
PLACED DOWNWARDS AND THE WHITE CONNECTOR AND COLLAR ARE PLACED UPWARDS.
