Brake Pedal Travel - -50 to 200 mm (-1.97 to 7.87 in)

This data represents the chord length translation position of the brake pedal through its normal range of movement.

BPP Sensor Rate - 0 to +10%/25 ms

This data indicates the rate of change of the brake pedal.

BPP Sensor Input Voltage - 0 to 5 Volts

This data represents the voltage being supplied to the BPP Sensor as measured by the EHPS system.

BPP Sensor Output Voltage - 0 to 5 Volts

This data represents a raw brake pedal position indicated by the voltage being received by the EHPS module from the BPP Sensor as measured by the EHPS system.

EHPS 42 V Bus Voltage - 0 to 76 Volts

This data indicates the voltage of the 42 V bus at the EHPS module.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
