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
