Electronic Brake Control Module Scan Tool Information
WARNING: This page is about a different car, the 2010 Chevrolet HHR. However, it is still accessible from the selected car via links, so may be relevant.
| Parameter | System State | Expected Value | Definition |
|---|---|---|---|
| Operating Conditions: Ignition ON | |||
| ABS Active | - | No | The scan tool displays Yes or No. The scan tool displays Yes if the ABS system is performing antilock braking. |
| ABS Failed | - | No | The scan tool displays Yes or No. Yes is displayed if there is an ABS fault. |
| Battery Voltage Signal | - | Varies | This displays volts. This is the voltage supplied to the EBCM. |
| Brake Fluid Level Status | - | OK | The scan tool displays OK or Low. This is the state of the brake fluid level sensor. |
| Brake Pressure Sensor Input | - | Varies | The scan tool displays 0-5 Volts. This voltage signal indicates the master cylinder hydraulic pressure applied to the system |
| BPP Signal | - | Released | The scan tool displays Applied or Released. The scan tool displays the applied state of the brake pedal position sensor. |
| Delivered Torque | - | 0% | The scan tool displays 0-100%. The duty cycle of the signal is used to transmit how much engine torque the ECM is delivering. Normal values are between 10-90 percent duty cycle. The signal is at low values (approximately 10 percent) at idle and at higher values under driving conditions. |
| DRP Active | - | No | The scan tool displays Yes or No. The scan tool displays if the EBCM is performing dynamic rear proportioning. |
| DRP Disabled | - | No | The scan tool displays Yes or No. The scan tool displays if the EBCM is no longer able to perform dynamic rear proportioning. |
| Engine Drag Control Failed | - | No | The scan tool displays Yes or No. Indicates if the EBCM disabled engine drag control due to a malfunction. |
| Lateral Accelerometer Input | - | 0.0 m/s 2 | The scan tool displays m/s 2 . This is the current rate of the vehicle acceleration or deceleration as reported by the lateral accelerometer sensor. |
| LF Wheel Speed Sensor | - | 0 km/h (0 mph) | This displays km/h (mph). This is the current speed of the left front wheel speed sensor. |
| LF Inlet Solenoid Command | - | Off | The scan tool displays On or Off. On is displayed when the left front inlet valve solenoid is commanded on. |
| LF Outlet Solenoid Command | - | Off | The scan tool displays On or Off. On is displayed when the left front outlet valve solenoid is commanded on. |
| LR Wheel Speed Sensor | - | OK | The scan tool displays OK or Low. This is the state of the washer fluid level. |
| LR Inlet Solenoid Command | - | Off | The scan tool displays On or Off. On is displayed when the left rear inlet valve solenoid is commanded on. |
| LR Outlet Solenoid Command | - | Off | The scan tool displays On or Off. On is displayed when the left rear outlet valve solenoid is commanded on. |
| Panic Brake Assist Failed | - | No | The scan tool displays Yes or No. Indicates if the EBCM disabled Panic Brake Assist due to a malfunction. |
| Pump Motor Command Voltage | - | Varies | This displays Volts. The scan tool displays the voltage applied to the ABS pump motor. |
| Requested Torque | - | 0% | The scan tool displays 0-100%. The duty cycle of the signal is used to transmit how much torque the EBCM is requesting the ECM to deliver. Normal values are between 10-90 percent duty cycle. The signal should be at 90 percent duty cycle when traction control is not active and at lower values (approximately 10 percent) when traction control is active. |
| RF Inlet Solenoid | - | Off | The scan tool displays On or Off. On is displayed when the right front inlet valve solenoid is commanded on. |
| RF Outlet Solenoid | - | Off | The scan tool displays On or Off. On is displayed when the right front outlet valve solenoid is commanded on. |
| RF Wheel Speed Sensor | - | 0 km/h (0 mph) | This displays km/h (mph). This is the current speed of the right front wheel speed sensor. |
| RR Inlet Solenoid Command | - | Off | The scan tool displays On or Off. On is displayed when the right rear inlet valve solenoid is commanded on. |
| RR Outlet Solenoid Command | - | Off | The scan tool displays On or Off. On is displayed when the right rear outlet valve solenoid is commanded on. |
| RR Wheel Speed Sensor | - | 0 km/h (0 mph) | This displays km/h (mph). This is the current speed of the right front wheel speed sensor. |
| Steering Position Sensor Signal | - | Varies | This displays degrees. This is the signal received from the steering angle sensor. |
| TCS Active | - | No | The scan tool displays Yes or No. The scan tool displays if the EBCM is requesting torque reduction from the ECM. |
| TCS Failed | - | No | The scan tool displays Yes or No. The scan tool displays if the EBCM is no longer able to perform traction control. |
| VSES Active | - | No | The scan tool displays Yes or No. 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 | - | 0.0 °/sec | The scan tool displays the signal received from the yaw rate sensor. |
