2007 chevy trailblazer code co131 brakes capliars locking up


DTC C0131 Antilock Brake System (ABS)/Traction Control System (TCS) Pressure Circuit

The master cylinder pressure sensor is located within the brake pressure modulator valve (BPMV). The master cylinder pressure sensor signal, to the electronic brake control module (EBCM), increases as hydraulic pressure in the front brake circuit increases.

Conditions for Setting the DTC co131
Any of the following conditions may cause the DTC to set.
• The EBCM detects open master cylinder pressure sensor circuitry.
• The EBCM detects shorted master cylinder pressure sensor circuitry.
• The master cylinder pressure sensor self-test, which occurs at power-up, fails.
• The zero-pressure signal voltage is not within an acceptable range.
• The master cylinder pressure is not within an expected tolerance based on deceleration rate and other data available to the EBCM.

How can I fix my stabilitrak on my 2010 chev impala


What's wrong with it ? Need more info . Light on ? The first thing to do would be to have the vehicle checked for DTC'S - diagnostic trouble codes ! Get a diagnostic direction , not just replacing parts . Need a professional grade scan tool . Plus reading how stabilitrak works would also be a good Idea . StabiliTrak General Motors Stability Control

Vehicle Stability Enhancement System (VSES)
The vehicle stability enhancement system (VSES) adds an additional level of vehicle control to the electronic brake control module (EBCM).
Yaw rate is the rate of rotation about the vehicle's vertical axis. The lateral accelerometer measures the sideways acceleration of the vehicle. The VSES is activated when the EBCM determines that the desired yaw rate and lateral forces do not match the actual attitude of the vehicle.
The desired attitude of the vehicle are calculated from the following inputs:
• The position of the steering wheel
• The speed of the vehicle
• The lateral, or sideways acceleration of the vehicle
• Yaw rate of the vehicle
• Master cylinder brake pressure
The difference between the desired yaw rate and the actual yaw rate is the yaw rate error, which is a measurement of oversteer or understeer. If the yaw rate error becomes too large, the EBCM attempts to correct the vehicle's yaw motion by applying differential braking to the appropriate wheel. The amount of differential braking applied to the left or right front wheel is based on both the yaw rate error and side slip rate error.
The VSES activations generally occur during aggressive driving, in turns, or on poor road conditions, without much use of the accelerator pedal. When braking during VSES activation, the pedal pulsations feel different than the ABS pedal pulsations. The brake pedal pulsates at a higher frequency during VSES activation.

There a number of DTC'S that can set .
DTC C0035-C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0179
DTC C0186
DTC C0196
DTC C0201
DTC C0242 or P0856
DTC C0245
DTC C0292
DTC C0558
DTC C0561
DTC C0563
DTC C0710

Do you know what DTC'S are , and a diagnostic flow chart ?

Abslight stays on. How to fix? This is a2007trailblazer?


First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0186
DTC C0196
DTC C0201
DTC C0240
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0245
DTC C0283
DTC C0287
DTC C0290 or C0292
DTC C0455
DTC C0550
DTC C0558

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit

Have new brakes brake sensors all the way around new rotors also abs stability traction lights are still on how do i turn them off


Have you had the car diagnosed ? Need to have vehicle hooked up to professional type scan tool .Check for DTC'S - diagnostic trouble codes . Brakes & rotors have nothing to do with electronics of the Anti-lock brakes an stability an traction control systems .Bad brakes & rotors will turn on the red brake light. The brake sensors as you call them are really wheel speed sensors . There is a EBCM - electronic brake control module , wheel speed sensors ,Plus some other thing's.
This vehicle is equipped with the DBC7.4 antilock braking system.
The vehicle is equipped with the following braking systems:
?€¢
Antilock Brake System (ABS)


?€¢
Dynamic Rear Proportioning (DRP)


?€¢
Traction Control System (TCS)


?€¢
Vehicle Stability Enhancement System (VSES) (w/JL4)

The following components are involved in the operation of the above systems:
?€¢
Electronic brake control module (EBCM)--The EBCM controls the system functions and detects failures.


The EBCM contains the following components:


-
System relay--The system relay is energized when the ignition is ON and no ABS DTCs are present. It supplies battery positive voltage to the solenoid valves and pump motor.


-
Brake pressure sensors--The EBCM contains 2 brake pressure sensors that monitor applied master cylinder pressure to the wheels. The EBCM uses the brake pressure inputs to enhance VSES.


-
Vent tube--The vent tube, located in the EBCM connector, is an opening to the internal cavity of the EBCM. It allows ventilation of the EBCM internals.


?€¢
Brake pressure modulator valve (BPMV)--The BPMV contains the hydraulic valves and pump motor that are controlled electrically by the EBCM. The BPMV uses a 4 circuit configuration with a diagonal split. The BPMV directs fluid from the reservoir of the master cylinder to the left front and right rear wheels and fluid from the other reservoir to the right front and left rear wheels. The diagonal circuits are hydraulically isolated so that a leak or malfunction in one circuit will allow continued braking ability on the other.


Important: There is a rubber isolator located under the BPMV and on the mounting studs. The rubber isolators protect the BPMV and the EBCM from vehicle vibrations.


?€¢
The BPMV contains the following components:


-
Pump motor


-
Inlet valves (one per wheel)


-
Outlet valves (one per wheel)


-
Master cylinder isolation valves (one per drive wheel)


-
Prime valves (one per drive wheel)


?€¢
Wheel speed sensors (WSS)--As the wheel spins, the wheel speed sensor produces an AC signal. The EBCM uses this AC signal to calculate wheel speed. The wheel speed sensors are replaceable only as part of the wheel hub and bearing assemblies.


?€¢
Traction control switch--The TCS is manually disabled or enabled using the traction control switch.


?€¢
Brake pedal position (BPP) sensor--The EBCM receives a serial data message from the body control module (BCM) to indicate that the brake pedal is applied.


?€¢
Yaw rate sensor (w/JL4)--The EBCM uses the yaw rate sensor to determine the rate of rotation along the vehicle's vertical axis. The yaw rate sensor is packaged with the lateral accelerometer as a single component.


?€¢
Lateral accelerometer (w/JL4)--The EBCM uses the lateral accelerometer to determine the sideways acceleration of the vehicle. The lateral accelerometer is packaged with the yaw rate sensor as a single component.


?€¢
Steering wheel position sensor (SWPS) (w/JL4)--The EBCM uses the SWPS as an indication of the position and rotation of the steering wheel.


This vehicle can set multiple DTC'S
DTC C0035-C0052 DTC C0111-C0120 DTC C0121 DTC C0131-C0139 DTC C0163-C0165 DTC C0179 DTC C0186 or C0187 DTC C0196 DTC C0220-C0229 DTC C0241 or P0856 DTC C0242 DTC C0244 or P1689 DTC C0252 DTC C0253 or C0254 DTC C0281 or C081 DTC C0460 or C0461 DTC C0550 DTC C0561 DTC C0870 DTC C0899 DTC C0900 DTC C1100 DTC C1101
Your best bet is to take it to a qualified repair shop ! You have no idea of the complexity of your vehicle .
