Scan Tool Data Definitions

The scan tool displays 6.5-16.5 volts. The amount of battery voltage available at the Power Steering Control Module (PSCM).

The scan tool displays ambient temperature to 135°. The estimated power steering system temperature calculated from a combination of commanded motor current, voltage levels and input from a temperature sensor internal to the PSCM.

The scan tool displays 0-65 amps. The amount of current the PSCM is commanding to the power steering motor.

The scan tool displays 14.20 to -14.20 N.m (10.50 ft-lbs). the amount of torque being applied to the steering column shaft. A positive value indicates a right turn, a negative value indicates a left turn.

The scan tool displays 0.0-5.0 volts. the amount of signal voltage from the steering wheel position sensors signal 1 circuit.

The scan tool displays 0.0-5.0 volts. the amount of signal voltage from the steering position sensor's signal 2 circuit.

The scan tool displays 1 or 2. The number of the steering tuning selected for the vehicle. electric power steering (EPS) requires different tuning for different levels of assist depending on vehicle content. Steering tuning 1 is for vehicles with a 4 cyl engine, steering tuning 2 is for vehicles with a 6 cyl engine, steering tuning 3 is for the extended sedan.

The scan tool displays 562° to -562°. The amount of degrees the steering wheel has been turned from center. A positive value indicates a right turn, a negative value indicates a left turn.

The scan tool displays 0.25-4.75 volts. the amount of signal voltage from the torque sensor's signal 1 circuit.

The scan tool displays 0.25-4.75 volts. the amount of signal voltage from the torque sensor's signal 2 circuit.

The scan tool displays 0-255 km/h (0-158 mph). The actual speed of the vehicle.
