Braking system malfunction message appears when engine started

Problem with brake system. Check fluid level.

Have it hooked up to a scanner an checked for DTC'S - diagnostic trouble codes .

traction control light on . DTC'S - diagnostic trouble codes are stored in ABS control module pointing to the malfunction . Take to a qualified repair shop or to auto part store that can pull these code. DTC C0242 00: Engine Control Module (ECM) Indicated TCS Malfunction
DTC P0856: Traction Control Torque Request Circuit
The electronic brake control module (EBCM) and the engine control module (ECM) simultaneously control the traction control. The EBCM sends a serial data message to the ECM requesting torque reduction. When certain ECM DTCs are set, the ECM will not be able to perform the torque reduction for traction control. A serial data message is sent to the EBCM indicating that traction control is not allowed.
DTC C0561 4B: System Disabled Information Stored Calibration Not Learned
DTC C0561 54: System Disabled Information Stored Temparature High
DTC C0561 59: System Disabled Information Stored Component Protection Time Out
DTC C0561 71: System Disabled Information Stored Invalid Serial Data Received
DTC C0561 72: System Disabled Information Stored Alive Counter Incorrect
DTC C0561 74: System Disabled Information Stored Value of Signal Protection Calculation Incorrect
DTC C0561 75: System Disabled Information Stored Signal Above Allowable Range

Traction Control Off Indicator
The IPC illuminates the traction off indicator when the following occurs.
• The EBCM disables engine torque reduction due to a malfunction and sends a serial data message to the IPC requesting illumination.
• The driver manually disables VSES and engine torque reduction by pressing the traction control switch. The EBCM sends a serial data message to the IPC requesting illumination.

Doesn't have one ! The electronic brake control module turns it on an off when there is a problem ! Your light on ? DTC'S - diagnostic trouble codes stored .
Traction Off
The IPC illuminates the traction off indicator when the following occurs:
• The electronic brake control module (EBCM) inhibits the traction control system. The IPC receives a class 2 message from the EBCM requesting illumination. The traction control system is disabled when the following occurs:
- For Chevrolet only, the shift lever is in FIRST (1) or SECOND (2) gear. The EBCM receives a class 2 message from the powertrain control module (PCM) indicating the gear position.
- For Pontiac and Oldsmobile only, the body control module (BCM) detects that the traction control switch is pressed (signal circuit is low). The EBCM receives a class 2 message from the BCM indicating the switch status.
- The BCM detects that the park brake is engaged (signal circuit is low) and that the engine is on. The EBCM receives a class 2 message from the BCM indicating the park brake status.
- The PCM detects certain malfunctions and is unable to perform torque reduction requests from the EBCM. The EBCM receives a class 2 message from the PCM indicating that traction control cannot be performed.
• The EBCM detects a malfunction in the traction control system. The IPC receives class 2 messages from the EBCM requesting illumination of both the service vehicle soon and traction off indicators.
• The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.

Hello Kammy ,you have electronic problems ! Your best bet would have it towed to a qualified repair shop .
SERVICE BRAKE SYSTEM
Refer to Brake Warning System Description and Operation !
The instrument panel cluster (IPC) illuminates the brake warning indicator when one or more of the following occurs:
• The body control module (BCM) detects that the park brake is engaged. The IPC receives a class 2 message from the BCM requesting illumination.
• The electronic brake control module (EBCM) detects a low brake fluid condition. The IPC receives a class 2 message from the EBCM requesting illumination.
• The EBCM detects an ABS malfunction which disables dynamic rear proportioning (DRP). The IPC receives a class 2 message from the EBCM requesting illumination.
• The IPC performs the bulb check at the start of each ignition cycle. The brake warning indicator illuminates for approximately 3 seconds before turning OFF.
• The IPC detects a loss of class 2 communications with the BCM or with the EBCM.

When there are electronic problems the computers will not allow the vehicle to start , hooking up a factory or professional scan tool to see what the problem is is the first place to start .

It could be a lot of thing's ,define lost power ! Engine died an the light's lit on the instrument cluster ? Does the engine spin when you turn the key to start ? Did the malfunction light come on when the engine was running ? Do the headlamps work , shine bright ? Battery good , connections good ? What year is the vehicle ? Engine Ztec ?

It sounds like if this is a car with the brake interlock, meaning the car will not shift from park unless the brake is pressed, there is a malfunction there, some are electronic and it may not be getting power to it especially if there are other warning lights on the dash. It would help if you could give more details, like which lights are on. Most cars with a mechanical interlock will have a cable you can adjust either at the brake cable or at the shifter.

You need to take it to a repair shop that knows this system an has a diagnostic tool to scan for codes . These systems are very complex an your average person with out training should not attempt to fix it.
Traction Off The IPC illuminates the traction off indicator when the following occurs:

With the light lit there are DTC'S - diagnostic trouble codes stored in the EBCM -
TRAC OFF
Traction Off: Refer to ABS Description and Operation in Antilock Brake System

Probably a sensor. But when u dont post kind of vehicle nobody can answer.

need to replace brake switch intermittent problem with them ....for lights bas, abs,asr,to go off..
