control module functions will be modified if the
battery voltage falls below or rises above
programmed thresholds.
Pump Motor Driver (V): This parameter indicates the
operational condition of the pump motor driver
(transistor).
RF Wheel Speed, LF Wheel Speed, RR Wheel Speed
and LF Wheel Speed (km/h, MPH): Wheel speed
is an ABS control module internal parameter. It is
