Data List Reference Table
The following items of ASC-ECU input data can be read using scan tool MB991958.
The system is normal

| 66 | Engine torque | Displays the engine torque. | |
| 67 | APS | Displays the accelerator pedal opening angle. | |
| 68 | Allow ESP torque request | Allow | |
| 70 | Target gear | When the selector lever is operated | Displays the selector lever position. |
| 71 | Actual gear | ||
| 72 | Master cylinder pressure offset | The difference between the neutral position that was input to the ASC-ECU before the master cylinder pressure sensor calibration and the neutral position after the calibration. | -10 to 10 bar |
| 73 | Lateral G sensor offset | The difference between the neutral position that was input to the ASC-ECU before the G and yaw rate sensor calibration and the neutral position after the calibration. | -0.23 to 0.23 G |
| 96 | G sensor offset | The difference between the neutral position that was input to the ASC-ECU before the G and yaw rate sensor calibration and the neutral position after the calibration. | -0.23 to 0.23 G |
| 97 | Yaw rate sensor offset | The difference between the neutral position that was input to the ASC-ECU before the G and yaw rate sensor calibration and the neutral position after the calibration. | -6.0 to 6.0 deg/s |
| 98 | Steering angle offset | The difference between the neutral position that was sent to the ASC-ECU before the steering wheel sensor calibration and the neutral position after the calibration. | -10 to 10 deg |
| 120 | Parking brake switch (Input) | When the parking brake lever is pulled up: | ON |
| When the parking brake lever is released: | OFF | ||
| 128 | ASC OFF switch | When the ASC control is activated by operating the ASC OFF switch | ON |

NOTE:
While ASC-ECU is disabled by the diagnostic function, the scan tool MB991958 displayed data is different from the actual measurement.
