U0121Lost Communication With Anti-Lock Brake System (ABS) Control Module

A module on the communication network has stopped receiving messages from the ABS (anti-lock brake) control module. In practice, the car can no longer communicate with the system that manages anti-lock braking and usually traction/stability control. Normal braking generally still works, but the safety-assist features (ABS, traction control, stability control) are typically disabled. It is often caused by lost power to the ABS module or a network wiring problem.

Ամենատարածված պատճառներն են՝ Loss of power or ground to the ABS module (blown fuse, corroded connector), Damaged, broken, or shorted CAN bus wiring to the ABS module, Corroded, loose, or backed-out connector pins at the ABS module, Another module disrupting the communication bus, Failed or faulty ABS control module։

Խուսափեք վարելուց — այս անսարքությունը կարող է վտանգավոր լինել կամ ավելի մեծ վնաս հասցնել։ Անմիջապես ստուգել տվեք։

Have this checked soon, because ABS, traction control, and stability control are likely disabled even though basic braking still works. Drive gently and allow extra stopping distance, especially in rain, ice, or hard braking, until it is repaired. A technician will check ABS module power, grounds, and the network wiring before replacing parts.
