| Table 1: | Electronic Brake Control Module Scan Tool Data Parameters |
| Table 2: | Electronic Brake Control Module Scan Tool Output Controls |
The electronic brake control module (EBCM) scan tool data parameters list contains all ABS related parameters that are available on the scan tool. The list is arranged in alphabetical order. A given parameter may appear in any one of the data lists.
Parameter | System State | Expected Value | Description |
|---|---|---|---|
Operating Conditions: Vehicle in Service Mode | |||
ABS Pump Motor Voltage | - | Varies | The scan tool displays the pump motor voltage. |
Antilock Braking System | - | Inactive | The scan tool displays Inactive or Active. Active is displayed when the antilock braking system is in traction control event. |
Antilock Braking System Status | - | No | The scan tool displays No or Yes. If there is an ABS malfunction the scan tool will display Yes. |
Brake Controls Brake Pedal Position Sensor Circuit 1 | - | Varies | This displays volts. This is the brake controls brake pedal position sensor circuit 1 reference value. |
Brake Controls Brake Pedal Position Sensor Circuit 2 | - | Varies | This displays percentage. This is the brake controls brake pedal position sensor circuit 2 that calculates the percentage of brake pedal applied or released. |
Brake Controls Brake Pedal Position Sensor without Offset | - | Varies | This displays mm. This is the value used to compare the position of the primary piston sensors. |
Brake Controls Brake Pedal Position Sen. 5 Volt Supply Voltage | - | Varies | This displays volts. This is the voltage supply to the brake controls brake pedal position sensor. |
Brake Controls Brake Pedal Position | - | Varies | The scan tool displays the brake pedal counts. Learned or Not Learned. This is the brake controls brake pedal position sensor zeroed or learned value. |
Brake Boost Power Status | - | Enabled | The scan tool displays Enabled or Disabled. |
Brake Master Cylinder Pressure Sensor | - | Varies | This displays psi/kpa. This is the current brake applied pressure. |
Brake Fluid Level Sensor | - | Varies | This displays volts. This is the voltage supply to the brake fluid level sensor signal. |
Brake Pedal Position Sensor Signal | Brake pedal released | Released | The scan tool displays Applied or Release depending on the state of the brake pedal. |
Brake pedal applied | Applied | ||
Brake Pressure Sensor | Brake pedal released | 0-1.55 V | The scan tool displays 0-5 V depending on the applied hydraulic brake pressure. |
Brake pedal applied | 1.55-5 V | ||
Dynamic Rear Proportioning Status | - | No | The scan tool displays No or Yes. If the EBCM disables the dynamic rear proportioning due to a fault the scan tool will display Yes. |
Engine Drag Control Status | - | No | The scan tool displays No or Yes. If the EBCM detects an ABS event, it sends a signal to the ECM to reduce engine power and Yes is displayed on the scan tool. |
High Pressure Accumulator Sensor | - | Varies | This displays the pressure of the accumulator. |
Ignition Voltage | - | Varies | This displays volts. This is the voltage status of the electronic brake control module (EBCM). |
Left Front Inlet Solenoid Valve Command | - | Off | The scan tool displays Off or On. On is displayed when the left front inlet solenoid valve is commanded ON. |
Left Front Outlet Solenoid Valve Command | - | Off | The scan tool displays Off or On. On is displayed when the left front outlet solenoid valve is commanded ON. |
Left Front Wheel Speed Sensor | - | 0 km/h (0 MPH) | The scan tool displays km/h (MPH) depending on the current speed of the left front wheel speed sensor. |
Left Rear Inlet Solenoid Valve Command | - | Off | The scan tool displays Off or On. On is displayed when the left rear inlet solenoid valve is commanded ON. |
Left Rear Outlet Solenoid Valve Command | - | Off | The scan tool displays Off or On. On is displayed when the left rear outlet solenoid valve is commanded ON. |
Left Rear Wheel Speed Sensor | - | 0 km/h (0 MPH) | The scan tool displays km/h (MPH) depending on the current speed of the left rear wheel speed sensor. |
Panic Brake Assist Status | - | No | The scan tool displays No or Yes. If the EBCM disables the panic brake assist due to a fault the scan tool will display Yes. |
Regenerative Braking Status | - | Active | The scan tool displays Active or Inactive. |
Right Front Inlet Solenoid Valve Command | - | Off | The scan tool displays Off or On. On is displayed when the right front inlet solenoid valve is commanded ON. |
Right Front Outlet Solenoid Valve Command | - | Off | The scan tool displays Off or On. On is displayed when the right front outlet solenoid valve is commanded ON. |
Right Front Wheel Speed Sensor | - | 0 km/h (0 MPH) | The scan tool displays km/h (MPH) depending on the current speed of the right front wheel speed sensor. |
Right Rear Inlet Solenoid Valve Command | - | Off | The scan tool displays Off or On. On is displayed when the right rear inlet solenoid valve is commanded ON. |
Right Rear Outlet Solenoid Valve Command | - | Off | The scan tool displays Off or On. On is displayed when the right rear outlet solenoid valve is commanded ON. |
Right Rear Wheel Speed Sensor | - | 0 km/h (0 MPH) | The scan tool displays km/h (MPH) depending on the current speed of the right rear wheel speed sensor. |
Steering Wheel Angle Sensor Signal | Steering wheel in straight position | -5 to +5° | The scan tool displays °. This is the current position of the steering angle sensor. |
Steering wheel turned left until stop | 450-550° | ||
Steering wheel turned right until stop | -550 to -450° | ||
System Voltage | - | 11-14 V | The scan tool displays V. This is the current battery voltage. |
