| Table 2: | Electronic Brake Control Module Scan Tool Output Controls |
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 Warning Lamp | -- | Off | The scan tool will display On or Off depending on the state of the ABS indicator. |
Brake Switch | -- | Released | The scan tool will display Applied or Released depending on the state of the brake switch. |
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). |
EBTCM to PCM Requested Torque | -- | Varies | The scan tool displays 0-100 percent. 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 torque the EBCM is requesting the PCM to deliver. Normal values are between 10 and 90 percent duty cycle. The signal should be at 90 percent duty cycle when traction control is not active and at a lower value approximately 10 percent when the traction control is active. |
Engine Speed | -- | 0 | The scan tool will display between 0 to 10200 RPM which is a digital tachometer display. |
Ignition Voltage | -- | B+ | The scan tool displays 0-17 Volts. The scan tool displays the level of ignition voltage at the EBCM. |
LF Inlet Solenoid Command | -- | Inactive | The scan tool displays Inactive or Active. Active is displayed when the left front inlet valve solenoid is commanded on. |
LF Outlet Solenoid Command | -- | Inactive | The scan tool displays Inactive or Active. Active is displayed when the left front outlet valve solenoid is commanded on. |
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. |
Low Traction Lamp | -- | Off | The scan tool will display On/Off. This will indicate the state of the LOW TRAC Indicator. |
LR Inlet Solenoid Command | -- | Inactive | The scan tool displays Inactive or Active. Active is displayed when the left rear inlet valve solenoid is commanded on. |
LR Outlet Solenoid Command | -- | Inactive | The scan tool displays Inactive or Active. Active is displayed when the left rear outlet valve solenoid is commanded on. |
LR 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. |
Motor Relay State | -- | Off | The scan tool display On/Off. This is the commanded state of the relay. |
PCM to EBTCM Delivered Torque | -- | Varies | The scan tool displays 0-100 percent. The scan tool displays the duty cycle of the Delivered Torque PWM signal. The duty cycle of the signal is used to transmit how much engine torque the PCM is delivering. Normal values are between 10 and 90 percent duty cycle. The signal is at low values approximately 10 percent at idle and at higher values under driving conditions. |
RF Inlet Solenoid | -- | Inactive | The scan tool displays Inactive or Active. Active is displayed when the right front inlet valve solenoid is commanded on. |
RF Outlet Solenoid | -- | Inactive | The scan tool displays Inactive or Active. Active 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. |
Rough Road Parameter | -- | 0 | The scan tool will display g. The scan tool will display the EBCM calculation of the road surface roughness. This information is then sent to the PCM over the class 2 serial data line. This information is used by the PCM for misfire detection. |
RR Inlet Solenoid Command | -- | Inactive | The scan tool displays Inactive or Active. Active is displayed when the right rear inlet valve solenoid is commanded on. |
RR Outlet Solenoid Command | -- | Inactive | The scan tool displays Inactive or Active. Active 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. |
Speed Range 1-4 Calibrated | -- | Yes | The scan tool displays Yes or No. Yes is displayed when the speed range has been calibrated |
Speed Range 1-4 Tire Pressure | -- | Yes | The scan tool displays Yes or No. Yes is displayed when the speed range and tire pressure are set. |
TCS Active | -- | No | The scan tool displays Yes or No. This is the state of the traction control system (TCS). |
TCS Switch State | -- | On | The scan tool displays On/Off. The scan tool will display the state of the Traction Control Switch. |
TCS Warning Lamp | -- | Off | The scan tool will display On or Off depending on the state of the TCS indicator. Valve Relay State |
TPM Indicator/Message | -- | Off | The scan tool displays Yes or No. This is the state of the tire pressure monitoring indicator/message. |
TPM System Enabled | -- | Yes | The scan tool displays Yes, or No. Yes indicates the TPM System has been enabled in the RCDLR. No indicates the TPM System has not been enabled in the RCDLR. |
Valve Relay Status | -- | On | The scan tool will display On/Off depending on the state of the VSES relay. |
Output Control | Description |
