Scan Tool Data Definitions
BATTERY VOLT
Battery voltage is an analog input signal read by the
ECU.
TQS (Torque sensor) POWER SUPPL
This parameter indicates the power supply voltage which
the EPS controller supplies to the torque sensor.
MOTOR VOLT
This parameter indicates the voltage between motor
terminals.
TQS (Torque sensor) MAIN TORQUE
The torque sensor is installed to detect the steering force
and the steering direction. It consists of two
potentiometers and the main torque sensor is one of
these.
TQS (Torque sensor) SUB TORQUE
The torque sensor is installed to detect the steering force
and the steering direction. It consists of two
potentiometers and the sub-torque sensor is one of
these. Its output characteristics are compared with those
of the main torque sensor.
ASSIST TORQUE
This parameter is an internal parameter of the EPS
controller. It is obtained by computing the torque sensor
input signal.
MOTOR (CON)
Based on the input signal, the EPS controller determines
the assist amount and controls the current to the motor
suitable for that assist amount. This parameter indicates
that control value.
MOTOR (MON)
This parameter indicates the actually measured value of
the current flowing to the motor. The motor circuit
condition is diagnosed by comparing this parameter with
“MOTOR (CON)” parameter described previously.
VEHICLE SPEED
The AC voltage signal produced by the vehicle speed
sensor (VSS) is divided and adjusted by the
speedometer and thus the vehicle speed signal is
obtained. The EPS controller determines the amount of
power assist based on this vehicle speed signal and the
torque sensor signal.
ENGINE SPEED
Engine speed signal is fed from the ECM so that it can
be used for trouble diagnosis of the electric power
steering system.
IGNITION SWITCH
This parameter indicates the condition of the power
supply through the ignition switch.
