Scan Tool Output Controls

WARNING: This page is about a different car, the 2004 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
Electronic Brake Control Module (EBCM)

Scan Tool Output Control Additional Menu Selection(s) Description
ABS Active Indicator Normal Mode Eavesdrop / No Phase Displays the status of the ABS indicator.
ABS Failed Lamp Command Normal Mode Eavesdrop / Phase 1-4 Displays the status of the ABS indicator.
ABS Reference Speed Normal Mode Eavesdrop / Phase 1-4 Displays the vehicle speed from the average of all four wheel speeds.
Automated Bleed - Used to bleed the ABS hydraulics. Refer to ABS Automated Bleed Procedure .
Automated Test - Cycles each solenoid valve and the pump motor in order to verify component operation. This test is identical to the Initialization Sequence. If a malfunction is detected, the EBCM will set the appropriate DTCs. The DTCs will be displayed upon completion of the test.
BPP Sensor Normal Mode Eavesdrop / Phase 1-4 Displays the current status of the BPP sensor.
BPP Sensor Calibration - Calibrates the BPP sensor.
CVRSS Equipped Normal Mode Eavesdrop / Phase 1-4 Indicates if the vehicle is equipped with road sensing suspension.
Engine RPM Normal Mode Eavesdrop / Phase 1-4 Displays the crankshaft rotation speed.
Engine Type Normal Mode Eavesdrop / Phase 1-4 Displays the type of engine in the vehicle.
Estimated Trans. Gear Normal Mode Eavesdrop / Phase 1-4 Displays the estimated state of the transmission gear.
Lateral Acceleration Normal Mode Eavesdrop / Phase 1-4 Displays the lateral acceleration from the lateral accelerometer signal.
LF Inlet Valve Solenoid Solenoid Test Commands the solenoid ON and OFF.
LF Outlet Valve Solenoid Solenoid Test Commands the solenoid ON and OFF.
LF TCS Isolation Valve Solenoid Test Commands the solenoid ON and OFF.
LF TCS Prime Valve Solenoid Test Commands the solenoid ON and OFF.
LR Inlet Valve Solenoid Solenoid Test Commands the solenoid ON and OFF.
LR Valve Outlet Solenoid Solenoid Test Commands the solenoid ON and OFF.
Normal Mode Eavesdrop - Monitors the serial data messages that relate to system operation. The normal mode eavesdrop is a list of data parameters. The normal mode eavesdrop function has the following 2 modes:
  • Phase 1-4-The term phase refers to the ignition switch changing states. The data parameters shown will display a value only when there is a change in the ignition state. Otherwise, the scan tool displays all asterisks next to each parameter.
  • No Phase-The data parameters shown are not affected by the changing of ignition states. The scan tool will display a value only when there is a serial data message that relates to the individual parameter. Otherwise, the scan tool displays all asterisks next to each parameter.
Powertrain TCS Failure Normal Mode Eavesdrop / Phase 1-4 Indicates if the PCM has suspended TCS due to a malfunction related to TCS.
Pump Motor Test - Commands the pump motor ON and OFF.
Red Brake Warning Indicator Normal Mode Eavesdrop / Phase 1-4 Displays the status of the Red Brake Warning indicator.
RF Inlet Valve Solenoid Solenoid Test Commands the solenoid ON and OFF.
RF Outlet Valve Solenoid Solenoid Test Commands the solenoid ON and OFF.
RF TCS Isolation Valve Solenoid Test Commands the solenoid ON and OFF.
RF TCS Prime Valve Solenoid Test Commands the solenoid ON and OFF.
Rough Road Parameter Normal Mode Eavesdrop / Phase 1-4 Displays the EBCM calculation of the road surface.
RR Inlet Valve Solenoid Solenoid Test Commands the solenoid ON and OFF.
RR Outlet Valve Solenoid Solenoid Test Commands the solenoid ON and OFF.
Service Stability System Normal Mode Eavesdrop / Phase 1-4 Displays the status of the Service Stability System message.
Service Steering System Normal Mode Eavesdrop / Phase 1-4 Displays the status of the Service Steering System message.
Stability System Active Normal Mode Eavesdrop / No Phase Displays the active status of the VSES.
State of Health Present Normal Mode Eavesdrop / Phase 1-4 Indicates if the EBCM is sending the proper state of health message.
Steering Position Sensor Test - Tests the steering wheel position sensor (SWPS) ability to provide a valid input.
Suspension Failure Status Normal Mode Eavesdrop / No Phase Displays the status of the road sensing suspension.
System Power Mode Normal Mode Eavesdrop / Phase 1-4 Displays the current state of the ignition as reported by the dash integration module (DIC).
TCC/Brake Switch Active Normal Mode Eavesdrop / Phase 1-4 Displays the status of the brake switch.
TCS Active Message Command Normal Mode Eavesdrop / No Phase Indicates if the EBCM is commanding the Traction Active indicator ON.
TCS Equipped Normal Mode Eavesdrop / Phase 1-4 Indicates if the vehicle is equipped with TCS.
TCS Failed Lamp Command Normal Mode Eavesdrop / Phase 1-4 Indicates if the EBCM is commanding the Traction Off indicator ON.
TCS Off Lamp Command Normal Mode Eavesdrop / No Phase Displays the status of the Traction message.
TCS On/Off Switch Normal Mode Eavesdrop / No Phase Displays the state of the traction control switch.
TCS On/Off Test - Commands the traction control system ON and OFF. Performs the same function as the traction control switch.
TCS Test - Runs the pump motor in order to apply fluid pressure to the front wheel circuits.
Temporary Inhibit of TCS Normal Mode Eavesdrop / Phase 1-4 Indicates if the EBCM has suspended the TCS due to a malfunction of the driver using the traction control switch.
TPS - Pedal Position Normal Mode Eavesdrop / Phase 1-4 Displays the percentage of throttle that is currently being applied.
Transmission Type Normal Mode Eavesdrop / Phase 1-4 Displays the type of transmission in the vehicle.
VIN Packet No. 2 Normal Mode Eavesdrop / Phase 1-4 Displays the VIN packet No. 2.
VSES Active Normal Mode Eavesdrop / Phase 1-4 Displays the current status of the VSES.
VSES Enabled Normal Mode Eavesdrop / Phase 1-4 Displays if VSES is currently enabled.
VSES Equipped Normal Mode Eavesdrop / Phase 1-4 Indicates if the vehicle is equipped with VSES.
VSES On/Off Switch
  • Normal Mode Eavesdrop / Phase 1-4
  • Normal Mode Eavesdrop / Phase 1-4
 Indicates the current state of the VSES switch.
VSES Ready Normal Mode Eavesdrop / Phase 1-4 Indicates that the steering wheel has been centered and the VSES is ready.
