U0152Lost Communication With Side Restraints Control Module - Left
- Generic OBD-II code · Network
- How the car detects it
- U0152 is the left-hand partner of U0153: a separate controller for the side restraints on the left no longer sends. In most cars side impacts are detected by satellite sensors in sills, B- or C-pillars that feed the central airbag unit; Bosch, for example, mounts its peripheral acceleration sensors on the left and right of the body and links them over the PSI5 sensor interface. Some architectures go further and give each side its own module on the vehicle bus, and only those can set this code. No manufacturer documents U0152 publicly. The listener, usually the main restraints module, logs the loss when the periodic message of the left unit is missing while voltage is in range. The airbag lamp lights and left-side or curtain protection may be lost; there is no MIL. U0151 is the main module, U0453 invalid data from the left unit.
