Electronic Brake Control Module Scan Tool Data Parameters
| Parameter | System State | Expected Value | Description |
|---|---|---|---|
| Operating Conditions: Ignition ON | |||
| ABS Active | - | No | The scan tool displays Yes or No. Yes is displayed if the ABS system is engaged. |
| 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 status of the electronic brake control module (EBCM). |
| Brake Fluid Level Status | - | OK | The scan tool displays OK or Low. This is the state of the brake fluid level. |
| BPP Signal | - | Released | The scan tool displays Applied or Released. This is the state of the brake pedal. |
| DRP Active | - | No | The scan tool displays Yes or No. This is the state of the dynamic rear proportioning (DRP). |
| DRP Disabled | - | No | The scan tool displays Yes or No. This is the state of the dynamic rear proportioning (DRP). |
| Engine Drag Control Failed | - | No | The scan tool displays Yes or No. The state of the engine drag control depends on the state of traction of the tires and engine RPM. |
| 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. |
| Panic Brake Assist Failed | - | No | The scan tool displays Yes or No. The state of the panic brake assist depends on the state of traction of the tires and engine RPM. |
| Pump Motor Command Voltage | - | Varies | This displays Volts. This is the voltage status of the EBCM pump motor command. |
| Requested Torque | - | Varies | The scan tool displays 0-10%. The scan tool displays the duty cycle of the Requested Torque PWM signal. The duty cycle of the signal is used to transmit how much engine torque the EBCM is requested. |
| RF Inlet Solenoid Command | - | Off | The scan tool displays On or Off. On is displayed when the right front inlet valve solenoid is commanded on. |
| RF Outlet Solenoid Command | - | 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. |
| Rear Inlet Solenoid Command | - | Off | The scan tool displays On or Off. On is displayed when the right rear inlet valve solenoid is commanded on. |
| Rear Outlet Solenoid Command | - | Off | The scan tool displays On or Off. On is displayed when the right rear outlet valve solenoid is commanded on. |
| Rear Wheel Speed Sensor | - | 0 km/h (0 mph) | This displays km/h (mph). This is the calculated speed of the rear wheels from the ECM. |
| TCS Active | - | No | The scan tool displays Yes or No. This is the state of the traction control system (TCS). |
| TCS Failed | - | No | The scan tool displays Yes or No. This is the state of the traction control system (TCS). |
Electronic Brake Control Module Scan Tool Output Controls
| Output Control | Description |
|---|---|
| ABS Motor Test | This is used in order to command the ABS pump motor On or Off. |
| Automated Bleed | This is used in order to bleed ABS hydraulics. |
| LF Inlet Valve Solenoid | Commands the solenoid ON and OFF. |
| LF Outlet Valve Solenoid | Commands the solenoid ON and OFF. |
| RF Inlet Valve Solenoid | Commands the solenoid ON and OFF. |
| RF Outlet Valve Solenoid | Commands the solenoid ON and OFF. |
| Rear Inlet Valve Solenoid | Commands the solenoid ON and OFF. |
| Rear Outlet Valve Solenoid | Commands the solenoid ON and OFF. |

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
