Scan Tool Data Definition
SCAN TOOL DATA DEFINITION
| Battery Volt (V) | Battery Voltage is an analog input signal read by the ESP® control module. Certain ESP® control module functions will be modified if the battery voltage falls below or rises above programmed thresholds. |
| Pump Motor Driver (V) | This parameter indicates the operational condition of the pump motor driver (transistor). |
| RF Wheel Speed, LF Wheel Speed, RR Wheel Speed and LR Wheel Speed (km/h, MPH) | Wheel speed is ESP® control module internal parameter. It is computed by reference pulses from the wheel speed sensor. |
| Brake Switch (ON, OFF) | This switch signal informs the ESP® control module whether the brake is active or not. |
| G Sensor (G) | Vehicle acceleration is measured by yaw rate/G sensor assembly and output to ESP® control module by pulse signal for 4WD vehicle. |
| Master Cyl Press (MPa) | Brake fluid pressure from brake master cylinder. |
| G Sensor (lateral) (G) | Lateral acceleration is measured by yaw rate/G sensor assembly and output to ESP® control module by pulse signal. |
| Yaw rate sensor (Deg/s) | Yaw rate sensor is measured by yaw rate/G sensor assembly and output to ESP® control module by pulse signal. |
| Steering angle Sen (°) | Steering wheel rotation angle is measured by steering angle sensor and output to ESP® control module by pulse signal. |
| Stability control (ACTIVE, INACTIVE) | This indicates stability control in activation/deactivation. |
| TCS control (brake) (ACTIVE, INACTIVE) | This indicates brake function of TCS in activation/deactivation. |
| TCS control (engine) (ACTIVE, INACTIVE) | This indicates torque control of TCS in activation/deactivation. |
| ESP® off state (cont) (ESP® ON, ESP® OFF) | State of ESP® OFF switch. |
| Steering angle Sen (Neutral, Non-Neutral) | This indicates steering wheel angle measured by steering angle sensor is in straight-ahead or not. |
