Scan Tool Data Definitions

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.

The scan tool displays 8-17 volts. The level of battery voltage available at the PSCM.

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.

The scan tool displays the number of times the ignition has been cycled since the last EPS DTC was set.

The scan tool displays 0-17 volts. The level of ignition voltage available at the PSCM.

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.

The scan tool displays 7.0-14.0 volts. The amount of voltage being supplied to the EPS motor while turning right.

The scan tool displays 7.0-14.0 volts. The amount of voltage being supplied to the EPS motor while turning left.

The scan tool displays the number of times the EPS system has entered into overload protection mode.

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).

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.

The scan tool displays 0-255 km/h (0-156 mph). The actual speed of the vehicle.

The scan tool displays the number of times the EPS system battery voltage has gone from 9-11 volts.
