Shift Force Sensor (if fitted)
The shift force sensor is used to detect when a force is applied to the gear change pedal.
Voltage Characteristics
NOTICE
The voltage characteristics for the shift force sensor will vary depending on the type of
foot controls fitted to the motorcycle.
Rocket 3 GT models are fitted with foot controls that are mounted towards the front of
the engine as standard (forward mounted foot controls). In this configuration, the shift
force sensor is in tension during up shifts.
Rocket 3 R and Rocket 3 TFC models are fitted with foot controls that are mounted
towards the rear of the engine as standard (rear mounted foot controls). in this
configuration the shift force sensor is in compression on up shifts.
Accessory kits are available to allow owners to equip their motorcycle with either
forward or rearward mounted foot controls. A function is available in the Triumph
diagnostic tool to allow the shift force sensor voltage characteristics to be adjusted to
match the type of foot controls installed. The Triumph Shift Assist system will not
function if the shift force sensor voltage characteristics are not correctly adjusted to
the type of foot controls installed. Refer to the fitting instructions provided with
accessory foot control kits for further details.
The sensor output voltage changes as follows during normal operation:
Sensor State
Voltage
At rest
2.6 V
In compression
1.6 V
In tension
3.6 V
The sensor voltage can be read using the Triumph diagnostic tool.
Further diagnostics
Refer to Shift Force Sensor Circuit (Triumph Shift Assist) for details of pinpoint tests
relating to diagnostic trouble codes P1702 and P1703.
