U0137 code: Lost Communication With Trailer Brake Control Module
Code U0137 is named in 4 US owner complaints. Models: 3, model years 2015–2020.
What the code means
Lost Communication With Trailer Brake Control Module. Generic meaning per SAE J2012 (the same for all makes).
How to read U0137: the letter U means network communication between modules; the second digit 0 marks a generic SAE code shared by all makes; the last three characters 137 identify the specific fault.
ABS/ESC codes: wheel speed sensors, the ABS hydraulic unit and pump, brake booster, pressure and yaw sensors. A hit to a wheel or suspension often damages the wheel speed sensor or its wiring, so on a damaged car this code is a reason to inspect the hub, knuckle and control arms, not just swap the sensor.
