C1256 BUICK, CADILLAC, CHEVROLET, GMC, PONTIAC, SATURN: EBCM INTERNAL MALFUNCTIONS
Previously, cars used hydraulic braking systems without the supervision of any electrical system. However, manufacturers have developed various safety features for braking, including sensors and controllers. In these systems, each wheel has a speed sensor. A speed sensor is also installed for the transmission, and the valves have changed from hydraulic to electronic. All of them work together for the right operation of the brakes and traction control.
The EBCM (Electronic Brake Control Module) is installed in the engine compartment next to the brake fluid reservoir. The EBCM takes several sensor inputs and compares the current sensor status with the associated logic maps and reactions in its on-board memory.
When the DTC C1256 OBDII code is stored, it means that the Electronic Brake Control Module detects an internal malfunction.
The C1256 OBD2 fault code C1256 is stored because of the following reasons:
