•

if shorted to positive: check the value shown by the parameter of the right Throttle Grip

Position Sensor - track D: disconnect the right side connector and see the value displayed

by the Axone: if the voltage does not vary, there is a short circuit in the cable wiring; replace

the throttle grip sensor if the voltage drops to zero.

•

if the circuit is open, short circuit to negative: check the throttle grip sensor connector and

the Marelli control unit connector. If not OK, restore. If OK, check circuit continuity between

the two cable terminals. If not OK, restore; if OK, check the cable earth insulation (from the

throttle grip sensor connector or the control unit connector): if the cable is not earth insulated,

restore the wiring. If it is earth insulated, and with the switch key set to ON, check that there

is power supply for the potentiometer PIN D and that PIN F is connected to earth. If both are

correct, replace the throttle grip sensor; if not, check the continuity of the cable that is not

functioning properly: if there is continuity, replace the control unit; if not, restore the wiring.

AXONE: 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.
