The usual reason for abs lights to stay on is the failure on one or mor of the ABS sensors fitted to each wheel. Changing these can be expensive as they are easy to destroy when taking them out. Get it proffesionaly checked to find out which is/are at fault.

    Hi. This sounds like a problem with one or more of the ABS wheel sensors. They are expensive to replace and damage easily when removing them. Get the systerm professionaly checked to see which is at fault before attempting to replace.

2007 chevy silverado check engine light code CO201


ABS code not check engine light code .
DTC C0201 00: Antilock Brake System (ABS) Enable Relay Contact Circuit
The solenoid relay, located within the electronic brake control module (EBCM), supplies battery voltage to all of the valve solenoids.
Circuit/System Verification
With scan tool installed, clear the DTCs then drive the vehicle in a straight line at a speed greater than 20 km/h (13 mph). If the DTC did not set as a current DTC see diagnostic aids.
Circuit/System Testing
Test for an open or a short to ground in the battery positive voltage circuit to the EBCM. Verify no open or a short to ground is found.
Test the EBCM ground circuit, an open or high resistance.
? If an open or a short to ground is found, repair the circuit.
Replace the EBCM assembly.

DTC C0201 (Equal to or over 8600 GVW)
The system relay, located within the electronic brake control module (EBCM), supplies battery voltage to all of the valve solenoids and to the Antilock Brake System (ABS) pump motor. When the relay contacts close, the EBCM monitors the voltage supplied to the valve solenoids and compares this voltage to monitored ignition voltage.
Action Taken When the DTC Sets
• The EBCM disables the ABS/DRP.
• The ABS indicator turns ON.
• The brake warning indicator turns ON

How to diagnose an ABS problem


You need to find out what code is stored in the ABS control module, if the light is on there is a DTC an the system is disabled ! Don't know if auto part stores can pull ABS codes or not , You'll have to check it out . Personally I say take it to a ASE certified repair shop if you don't know anything about anti lock brakes !
?€¢
Electronic Brake Control Module (EBCM) -- The EBCM controls the system functions and detects failures.


The EBCM contains the following components:


?€¢
System Relays -- The inlet and outlet solenoid relay is energized when the ignition is ON and no ABS DTCs are present. It supplies battery positive voltage to the solenoid valves, the pump motor relay is energized and supplies battery positive voltage to the pump motor when ABS is activated.


?€¢
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.


This system can store 10-12 DTC's for something simple as wheel speed sensors to wiring problems to a malfunction of the EBCM . Some of these problems you would need a professional type scan tool ! The antilock brake system on your vehicle is the
BOSCH 8.0 antilock braking system
The vehicle is equipped with the following braking systems:
?€¢
Antilock Brake System (ABS)


?€¢
Dynamic Rear Proportioning (DRP)


?€¢
Traction Control System (TCS) (w/NW7)

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 Relays -- The inlet and outlet solenoid relay is energized when the ignition is ON and no ABS DTCs are present. It supplies battery positive voltage to the solenoid valves, the pump motor relay is energized and supplies battery positive voltage to the pump motor when ABS is activated.


?€¢
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)


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


?€¢
Traction Control Switch (w/NW7) -- The TCS is manually disabled or enabled using the traction control switch.


?€¢
Stop Lamp Switch - The EBCM uses the stop lamp switch as an indication that the brake pedal is applied

How to reset brake lite on my 2005 X type jaguar?


which brake warning light is on? the xtype does not have pad wear sensors fitted. so i guess you mean the abs light or the handbrake light.more than likely its the abs light and the common problem is the reluctor rings on one or the other of the rear outer constant velocity joints corroded/ fell off get the fault codes out of the abs module to help.

What is the C0265 error code


The ABS EBCM anti-lock brake module is failing causing problems with the ABS pump running constantly, also will drain your battery.
  1. Remove the ABS fuse to prevent ABS motor burn out.
  2. You can still drive your vehicle with the module removed.
  3. We recommend covering the exposed surface of the hydraulic control unit with aluminum foil to keep out water and dirt.
Common Failures:
  • ABS Pump Always Running
  • Codes: C0265, C0267, C0268
  • Pump Motor Circuit trouble code
  • Power Relay trouble code
  • Valve Relay Trouble code
  • Dump Valves (solenoids) trouble codes
  • No Communication
  • Intermediate power loss

My tc and abs light are coming on all the


Speedo and traction control; check wheel sensors all 4, clean and blow the sensors and reactor rings.
Is ABS light on as well? if so, you need a EBTCM module mounted to the brake ABS pump facing the battery. There are places in the US that rebuild them with warranty for under $150.
