C0265 Engine Code: EBCM Relay Circuit - Diagnosis & Repair

https://chevytrucks.org > c0265-engine-code-repair
Aug 19, 2020 - On Chevy and GMC vehicles, this engine code is caused by a bad connection at the EBCM ground, which is located inside of the unit itself. If you ...

It sounds like there has to be an issue with the pump/modulator or even the master cylinder. I would try bleeding all 4 wheels first to see if there is any air trapped. If not you need to have the abs pump checked next

They seem to be related to ABS. Is your ABS service light on? If so, it could be a sensor.

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

Your best bet is to take it to a qualified repair shop ! You have no idea of the complexity of your vehicle .

there is no B0281 only a c0281 and that is your abs is malfunctioning because of the brake lamp switch. check connection on switch if it is fine you need a new switch

the c0281 code on a gm truck is the abs ECBM has lost the voltage to it when the brake pedal is not depressed. so if you are going at a speed above 10-15MPH and the ECBM looses the 12 volts to it ,when the brake pedal is NOT depressed ,, then this code gets generated. the brake switch has a 12 volt feed to the abs switch contact connector. the other side of this switch goes to the other connector pin. these switches wear out get dirty with time. replacing the switch or if your up to it take the switch apart and clean the contacts with a fine abrasive material to remove the oxidation. if pitted or worn replace the switch. one wire is brown the other is purple. working the brake pedal watching the volts is easy way to see if the voltage is steady when you wiggle the brake pedal.. driving on a rough road with a bad switch usually gets it acting up.

wheel sensor you need too reset withe scan tools

this is a code table hope it can help you and good luck

This C code is what is designated as a Chassis code . The specifc code is a generic and means

C0281 - Brake Switch Circuit:

It indicates a problem with the brake lamp circuit. Inspect the switch and circuit.

Code C0281 is set if computer never sees the brake switch release after speeds above 15 mph during start-up.

Could be a sticky pedal or the calipers not releasing properly !

Hope that helps !

go to auto zone ,they can help you get the codes and tell you how to fix them ,its free, hope to help,robert b
