that is not functioning properly: if there is continuity, replace the control unit; if not, restore
the wiring.
NAVIGATOR: LOGIC ERRORS
Left side Throttle Grip Position (tracks A-B) P0154 - illogical signals.
Error cause
•
Two illogical voltage signals have been detected at PINS 42 and 40 of the VEHICLE con-
nector (tracks A-B)
Troubleshooting
•
Check the parameters of the left Throttle Grip Position Sensor - tracks A and B: 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.
Right side Throttle Grip Position (tracks C-D) P0155 - illogical signal.
Error cause
•
Two illogical voltage signals have been detected at PINS 30 and 44 of the ENGINE con-
nector (tracks A-B)
Troubleshooting
•
Check the parameters of the left 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 - illogical signal.
Error cause
•
The value of the left side sensor (tracks A-B) does not coincide with the value of the right
side sensor (tracks C-D).
Troubleshooting
•
Replace the throttle grip sensor
RESET PROCEDURE
If the Marelli control unit or the throttle grip sensor is replaced, check the Handle self-learning with the
diagnosis instrument: once the check is completed, make sure that the Handle self-learning 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-
