Shift Force Sensor Diagnosis (if fitted)
The shift force sensor is used to detect when a force is applied to the gear change pedal.
Voltage Characteristics
The sensor output voltage changes as follows during normal operation:
Sensor State | Voltage |
|---|---|
At rest | 2.5 V |
In compression (up shift) | 2.5 V to 0.5 V |
In tension (down shift) | 2.5 V to 4.5 V |
The sensor voltage can be read using the Triumph diagnostic tool.
Further diagnostics
Refer to P1702, P1703 - Shift Force Sensor Circuit (Triumph Shift Assist) for details of pinpoint tests relating to diagnostic trouble codes P1702 and P1703.
Adaption
If Triumph Shift Assist is fitted as standard, the motorcycle is delivered from the factory with the shift force sensor fully adapted.
If the Triumph Shift Assist has been fitted as an accessory, the shift force sensor must be adapted as part of the accessory kit installation process.
The shift force sensor adaption must be reset and the sensor re-adapted under the following conditions:
If a shift force sensor malfunction occurs (DTC P1702 and P1703, see P1702, P1703 - Shift Force Sensor Circuit (Triumph Shift Assist)).
The sensor has been removed or disconnected for any reason.
Refer to Shift Force Sensor Adaption (if fitted).
