What does lost communication with anti lock brake system ( ABS ) mean?
Lost Communication With Anti-Lock Brake System (ABS) Control Module. What does that mean? This is a generic communication system diagnostic trouble code that applies to most vehicle makes and models. That may include but are not limited to vehicles from Mazda, Chevrolet, Dodge, VW, Ford, Jeep, GMC, etc.
What should I do if I lost communication with my abs?
If all tests have passed and communication is still not possible, or you were unable to clear the U0121 fault code, the only thing left that can be done is to seek assistance from a trained automotive diagnostician, as this would indicate a failed ABS module.
What should I do if my abs code does not return?
If the code does not return or communication is re-established, then the fuses/connections were most likely your problem. If the code returns, locate the CAN C bus communication connections on your particular vehicle, most importantly the ABS module connector.
