B0110 — Deployable Steering Column Circuit Fault (SRS)

Severity: high Drive with care, to a shop

What B0110 means

The SRS control module self-tests the circuit of the device that lets the steering column collapse or shift in a severe crash to reduce driver injury. B0110 means the module found an open, short, or out-of-range resistance in that circuit. Since correct operation can't be assured, it turns on the airbag warning light.

Symptoms

  • Airbag (SRS) warning light on or flashing
  • Horn doesn't work
  • Steering wheel cruise or audio buttons stop working
  • Code returns after being cleared
  • Light appears only when turning the wheel

Possible causes

  1. Faulty deployable column module
  2. Worn or broken clock spring
  3. Damaged wiring in the steering column
  4. Corroded or loose connectors under the column
  5. Faulty SRS control module (uncommon)
  6. Improper reassembly after a crash or repair

How to diagnose

  1. Scan with an SRS-capable tool and note any other codes
  2. Disconnect the battery and wait the specified time to prevent accidental deployment
  3. Inspect connectors under the column and at the SRS module for corrosion or looseness
  4. Check the column wiring for chafing or breaks
  5. Test the clock spring for continuity and resistance
  6. Check the circuit using service data procedures; never probe airbag circuits with an ordinary meter
  7. Find out whether the column or wheel was recently serviced
  8. Clear the code after repair and confirm it doesn't return

Common fixes

  • Replace the clock spring
  • Repair or replace damaged wiring
  • Clean or replace connectors
  • Replace the deployable column module
  • Replace or reprogram the SRS module if confirmed faulty

Questions and answers

What does B0110 mean?

The SRS module detected a fault in the circuit that controls the deployable steering column. That's why the airbag light comes on.

Can I fix an SRS circuit myself?

Airbag systems can deploy accidentally and cause injury. Unless you have training and service information, have a shop do it.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
