Data Definitions

WARNING: This page is about a different car, the 2004 GMC Sierra, 2004 GMC Cab & Chassis Sierra, 2004 Chevrolet Silverado, and 2004 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

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.
