Section 3: Riding Profiles, Power Modes & Lighting Management
Dedicated Performance Profiles and Automated Lighting Controls
The T154 interface allows riders to switch performance behaviors on the fly while automating auxiliary electrical accessories.
***Three Integrated Riding Modes:**
***ECO Mode:** Minimizes current draw to maximize overall battery efficiency and cruising range.
***CITY Mode:** Delivers linear, predictable power delivery tailored for urban traffic and daily commuting.
***SPORT Mode:** Unlocks full motor torque and rapid throttle/PAS response for off-road trails and steep ascents.
***Customizable Assist Levels:** Supports configurable assist gear counts from **1 to 8 assist levels**, as well as **Level 0** to disable motor assistance while keeping telemetry active.
***Walk Boost & Cruise Control:** Features a **6 km/h walk-assist mode** for pushing loaded bikes up steep grades, along with toggleable electronic cruise control.
***Intelligent Headlight & Taillight Control:**
* Integrated **photosensitive light sensor** on the display face enables automatic headlight activation when ambient light drops.
* Supports **Manual**, **Auto**, and **Always On** headlight operating modes.
* Taillight parameters support **Disable**, **On/Off** (3-wire brake lights), and **PWM** (2-wire brake lights) configurations.

Section 4: Advanced Motor Tuning, Sensor Calibration & Diagnostics
Torque Sensor Calibration and Real-Time Diagnostic Test Menu
Functioning as a mobile service terminal, the T154 Display gives mechanics direct access to sensor zeroing and hardware monitoring.
***Unloaded Startup Torque Sensor Calibration:** When paired with torque-sensing ToSeven DM01 or DM02 motors, the controller performs an automatic zero-point calibration at startup.
***
Critical Requirement:** The pedals and crank arms **must remain completely free of weight, feet, or mechanical load** during power-on to prevent improper zero-point voltage recording.
***Torque Sensor Parameter Adjustment:** Configure **Sensitive** or **Safe** operating modes, set **ZeroVol** (100 mV to 2000 mV), **MaxVol** (1000 mV to 3300 mV), **StartupNetVol** (200 mV to 2000 mV), and **KeepAngle** (0° to 180°) for smooth pedal engagement.
***Display Diagnostic Test Sequence:**
1. Set assistance to **Level 0**.
2. Short-press **POWER** rapidly until **'Test'** appears, then press **UP (^)**.
3. Short-press **POWER** until **'Drive'** appears.
4. Live monitoring fields verify real-time bus **Voltage (V)**, **Current (A)**, **Motor RPM**, **Controller & Motor Temperatures (°C)**, **PAS CADENCE (RPM)**, **Throttle Voltage**, and **Brake Lever Status (OFF when released, ON when squeezed)**.
