| LF Outlet Solenoid Command | - | Off | The scan tool displays Off or On. The scan tool displays ON when the left front outlet valve solenoid is commanded on. |
| RF Inlet Solenoid Command | - | Off | The scan tool displays Off or On. The scan tool displays On when the right front inlet valve solenoid is commanded on. |
| RF Outlet Solenoid Command | - | Off | The scan tool displays Off or On. The scan tool displays On when the right front outlet valve solenoid is commanded on. |
| LR Inlet Solenoid Command | - | Off | The scan tool displays Off or On. The scan tool displays On when the left rear inlet valve solenoid is commanded on. |
| LR Outlet Solenoid Command | - | Off | The scan tool displays Off or On. The scan tool displays On when the left rear outlet valve solenoid is commanded on. |
| Lateral Accelerometer Signal | - | 2.5 V | The scan tool will display 0-5 V. The scan tool displays approximately 2.5 V when the ignition is ON, and the vehicle is stationary. |
| Pump Motor Relay Command State | - | Off | The scan tool displays Off or On. The scan tool displays On when the pump relay is commanded on. |
| Pump Motor Relay Feedback State | - | Off | The scan tool displays Off or On. This is feedback state of the relay, to show the actual state of the pump relay. |
| Pump Motor Commanded Voltage | - | 0.0 V | The scan tool displays Voltage when the pump motor is commanded on. |
| Steering Wheel Position | Steering wheel at center | 0° | The scan tool will display the steering wheel angle. The scan tool will display the signal received from the steering wheel angle sensor. |
| Steering wheel at left lock | -720° | ||
| Steering wheel at right lock | 720° | ||
| TCS Active | - | No | The scan tool displays No or Yes. The is the state of traction control system (TCS). |
| TCS Failed | - | No | The scan tool displays No or Yes. This is the state of traction control system (TCS). |
| TCS On/Off | - | No | The scan tool displays On or Off. This is the requested status. |
| VSES On/Off Status | - | No | The scan tool displays On or Off. This is the requested status. |
| VSES Active | - | No | The scan tool displays No or Yes. The scan tool displays Yes when VSES is active, and No when VSES is inactive. |
| VSES Failed | - | No | The scan tool will display Yes or No depending on the state of the ABS indicator. |
| Yaw Rate Sensor Input | - | 2.5 V | The scan tool will display Volts, depending on the angle of the vehicle. |
