U0454 Invalid Data Received From Side Restraints Control Module - Right

U0454 is the right-hand counterpart of U0453. Where a separate side restraints unit on the right evaluates side impact sensing or fires the right side and curtain airbags, a partner, normally the central airbag controller, stores U0454 when it judges that unit's messages corrupt or implausible. Contact itself still exists; a silent right unit would be U0153. No manufacturer documents U0454 publicly. Bosch describes airbag controllers with inputs for peripheral crash sensors that detect side impacts, and FMVSS 214 sets the side impact requirements such units serve. Because FMVSS 208 demands a readiness indicator for deployable protection, the airbag lamp is the expected reaction, and protection on the right may be missing until repair. No MIL is involved.

Likely causes

Loose or corroded plug of the right side unit, for example under the right seat or in the B-pillar
Software or configuration of the right unit not matching the central airbag controller, often after a module swap
Internal fault of the right side restraints unit, for instance after a side impact on the right

Symptoms

  • Airbag warning lamp on
  • Side or curtain airbag on the right possibly unavailable
