Scan Tool Data Definition
SCAN TOOL DATA DEFINITION CHART
| Battery Volt (V) | Battery voltage is an analog input signal read by ESP® control module. ESP® control module functions may be stopped if battery voltage falls below or rises above programmed thresholds. |
| Pump Motor Driver (V) | This parameter indicates operational condition of 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 ESP® control module whether the brake is active or not. |
| Master Cyl Press (MPa) | This indicates brake fluid pressure from brake master cylinder. |
| G Sensor (Lateral) (G) | Lateral acceleration is measured by yaw rate/G sensor in ESP® control module. |
| G Sensor (In front and behind) (G) | Acceleration and deceleration is measured by yaw rate/G sensor in ESP® control module. |
| 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. |
| ESP® OFF SW State (ON, OFF) | This indicates state of ESP® OFF switch. |
| Steering Angle Sig (Neutral, Non N) | This indicates steering wheel angle measured by steering angle sensor is in straight-ahead or not. |
