• Read & Clear Codes across all ECUs, including historic and pending faults.
  
  
• Freeze Frame Data: Capture sensor snapshots at fault occurrence for deeper insight.
  
  
• Detailed Code Library: Manufacturer-defined descriptions guide precise fault interpretation.
  
  

3. Live Data Streaming & Logging

Monitor key parameters in real-time:

• Engine data (boost pressure, timing advance, EGR %, DPF status)
  
  
• Transmission stats (clutch temperatures, gear selector status)
  
  
• Vehicle network info (module voltages, bus errors)
  Graph data streams over time to identify intermittent or load-dependent issues.
  
  

4. Bi-Directional & Active Testing

Trigger and test individual components without manual inputs:

• Prime and bleed fuel systems
  
  
• Cycle cooling fans, AC compressor, fuel pump
  
  
• Perform ABS solenoid activation
  
  
• Calibrate adaptive air suspension and ride height sensors
  
  

5. Module Coding & Adaptation

• Long Coding: Unlock factory settings like daytime running light behavior, mirror fold on lock, seat heating presets.
  
  
• Basic Settings: Reset throttle body adaptations, calibrate idle speed, set new battery configuration.
  
  
• Transmission Adaptation: Reset clutch adaptation on ZF 8HP and JLR 8-speed units.
