Invalid Data Received From Restraints Occupant Classification System Module

A receiving module detected implausible data from the restraints occupant classification system (OCS) module. Seat-weight or pressure-mat values fail plausibility checks; passenger airbag enable/disable may default to enabled with the warning lamp on.

Affected components

  • Occupant classification module

Common causes

  • High likelihood: Module internal fault or sensor input drift
  • Medium likelihood: Software version mismatch after replacement
  • Low likelihood: Gateway module routing CAN messages incorrectly

Possible symptoms

  • Multiple warning lights may illuminate
  • Affected modules may go into limp mode or shut down
  • Specific functions inoperative depending on module
  • Diagnostic tools may show communication faults

Diagnostic notes

  • The malfunction indicator lamp may illuminate
  • A drive cycle may be required after repair
