B0005Collapsible Steering Column Deployment Control
- Generic OBD-II code · Body
- How the car detects it
- Some steering columns can change how much energy they soak up while collapsing in a frontal crash. In a Delphi/Nexteer patent a controller fires pyrotechnic actuators that force an absorber strap into a tighter path or couple in extra absorbers, matching the column to driver size and crash severity. B0005 is the restraint module code for the firing loop of such an actuator. Land Rover documents B0005-56, an invalid or incompatible configuration, on the Evoque from 2018 when a replacement restraints control module had received older software than the factory level; a manual patch of the diagnostic equipment fixes it (SSM 74577). FMVSS 204 caps rearward column travel at 127 mm when the car hits a barrier at 48 km/h. With the loop faulted, the column keeps its fixed default behaviour and the airbag lamp is on.
- What you may notice
- Airbag warning lamp on
- Adaptive energy absorption of the column unavailable, no effect on normal steering
- Safety note: the column actuator is pyrotechnic; leave tests and connector work to a workshop with the battery disconnected
- Likely causes
- LikelyRestraint module configuration or software does not match the vehicle (Land Rover SSM 74577)
- PossibleOpen or shorted lead to the pyrotechnic column actuator
- RareFaulty actuator in the steering column
