U0153Lost Communication With Side Restraints Control Module Right

  • Generic OBD-II code · Network
How the car detects it
U0153 means the airbag system no longer hears from the separate control module for the right-side restraints. Some vehicles split the job: a central airbag unit plus side units that evaluate side impact sensors and fire side or curtain bags. When the right unit's periodic messages stop, the receiving modules store U0153, in the same way GM's U0100-U02FF logic treats any silent node. No manufacturer documents U0153 publicly; GM's list stops at U0151 for its single sensing and diagnostic module. U0152 is the left-hand twin, U0151 the main restraints module. The airbag warning lamp comes on and side protection on the right may be unavailable; no MIL. Work on airbag components belongs in a workshop.
What you may notice
