Data Definitions

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.

EHPS Ignition 0- OFF/ON

This data represents the voltage of the Accessory signal at the EHPS module as read by the EHPS system.

EHPS Ignition 1 - OFF/ON

This data represents the voltage of the Ignition 1 signal at the EHPS module as read by the EHPS system.

EHPS Demand - -100 to +100%

This data represents the percentage of the available EHPS pump output being delivered as determined by the EHPS system.

EHPS Demand Speed - 0 to +7500 RPM

This data represents the current pump speed being commanded as determined by the EHPS system.

EHPS ECU Temperature - -180 to +180°C (-238 to +302°F)

This data represents the temperature of the EHPS module in the EHPS system as determined by the EHPS system.

EHPS Manifold Temperature - -180 to +180°C (-238 to +302 °F)

This data represents the temperature of the manifold in the EHPS system as determined by the EHPS system.

EHPS Motor Current - 0 to +200 A

This data represents the current being used by the EHPS motor as measured by the EHPS system.

EHPS Motor RPM - 0 to +7500 RPM

This data represents the rotational speed of the EHPS motor as determined by the EHPS system.

Steering Wheel Rate - 0 to 2048°/s

This data represents the approximate degrees per second change of the steering wheel as determined by the EHPS system.

Steering Wheel Sensor Phase A Volts - Low/High

This data represents the state of the Phase A digital output of the steering wheel sensor at the EHPS unit as currently read by the EHPS system.

Steering Wheel Sensor Phase B Volts - Low/High

This data represents the state of the Phase B digital output of the steering wheel sensor at the EHPS unit as currently read by the EHPS system.

Vehicle Speed - km/h (mph)

This data represents the calculated speed of the vehicle as determined by the PCM.
