For 1990-2009 cars only
Actual Motor Current: The scan tool displays 0.0 amps to 58.0 amps. The actual amount of current the Power Steering Control Module (PSCM) is commanding to the Electric Power Steering (EPS) motor.
Battery Voltage: The scan tool displays 8-17 volts. The level of battery voltage available at the PSCM.
Desired Motor Current: The scan tool displays 0.0 amps to 58.0 amps. The amount of current the PSCM is attempting to command to the EPS motor.
Ignition Cycles Since Last Code Set: The scan tool displays the number of times the ignition has been cycled since the last EPS DTC was set.
Ignition Voltage: The scan tool displays 0-17 volts. The level of ignition voltage available at the PSCM.
Lowest Limiting Current: The scan tool displays up to 65 amps. The amount of current last commanded to the EPS motor before the system went into overload protection mode. 65 amps indicates that an overload protection incident has not occurred.
Motor Voltage +: The scan tool displays 7.0-14.0 volts. The amount of voltage being supplied to the EPS motor while turning right.
Motor Voltage -: The scan tool displays 7.0-14.0 volts. The amount of voltage being supplied to the EPS motor while turning left.
Overload Protection Incidents: The scan tool displays the number of times the EPS system has entered into overload protection mode.
Steering Calibration: The scan tool displays 1-8. The number of the steering calibration the PSCM has chosen based on the VIN. All 8 of the steering calibrations for EPS are stored in the Body Control Module (BCM).
Steering Shaft Torque: The scan tool displays -20.70 N·m to 20.70 N·m (15.2 lb ft). The amount of torque being applied to the steering column shaft when turning the steering wheel. This signal voltage is from the detection coil of the torque sensor which is then converted to N·m by the PSCM. A - value indicates a left turn, a positive value indicates a right turn.
Vehicle Speed: The scan tool displays 0-255 km/h (0-156 mph). The actual speed of the vehicle.
9-11 Volt Battery Occurrences: The scan tool displays the number of times the EPS system battery voltage has gone from 9-11 volts.
Battery Voltage: The scan tool displays 8-17 volts. The level of battery voltage available at the PSCM.
