B0005 code meaning
Collapsible Steering Column Deployment Control
What B0005 means
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.
B0005 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of B0005
- 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
Common causes of B0005
- Most likelyRestraint module configuration or software does not match the vehicle (Land Rover SSM 74577)
- PossibleOpen or shorted lead to the pyrotechnic column actuator
- Less likelyFaulty actuator in the steering column
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B0005 means
| B | Body system: airbags, seat belts, power seats, lights and climate control. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 05 | The exact fault in that area. |
What to do next
- Note B0005 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about B0005
What does B0005 mean?
B0005 means "Collapsible Steering Column Deployment Control". Some steering columns can change how much energy they soak up while collapsing in a frontal crash. It is a generic code, so it means the same on every make.
Is it safe to drive with B0005?
B0005 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will B0005 fail an emissions test?
B0005 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is B0005 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will B0005 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
