| Table 2: | Electronic Brake Control Module Scan Tool Output Controls |
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 . |
Scan Tool Output Control | Description |
|---|---|
Automated Bleed | This is used in order to bleed ABS hydraulics. Refer to Antilock Brake System Automated Bleed Procedure . |
Steering Angle Sensor Centering | This is used to center the steering angle sensor. |
