Causes
- Open or short in driver airbag stage 2 squib circuit
- High or low squib resistance (out-of-spec)
- Faulty/contaminated airbag connector or wiring harness (steering column area)
- Worn or damaged clock spring (spiral cable)
- Poor chassis/connector grounds or corroded terminals
- Faulty SRS/airbag control module (less common)
Symptoms
- SRS / airbag warning lamp illuminated on instrument panel
- Driver airbag may be disabled (airbag light and DTC present)
- Possible multiple SRS fault codes logged
- Fault present after steering wheel work or collision repair
- No other drivability symptoms (electrical problem limited to SRS)
What to check
- Read and record all SRS codes and freeze-frame data with a capable scan tool
- Check battery voltage and charging system before diagnosing (stable 12 V+)
- Visual inspection of steering wheel, clock spring, and driver airbag connector
- Inspect wiring harness for damage, pinching or chafing between wheel and column
- Check connector terminals for corrosion, bent pins or poor contact
- Measure squib resistance and continuity at airbag connector and at SRS module
Signal parameters
- Squib resistance (ohms) — expected to be within manufacturer spec for driver stage 2
- Continuity of squib circuit between driver airbag connector and SRS module
- Supply voltage to SRS module (VBAT) and squib firing circuit voltage
- Present/latched fault status and freeze frame data from SRS control module
- Number of deployments recorded / readiness status flags
Diagnostic algorithm
- Read all SRS/airbag codes and freeze-frame using a scanner; note related codes.
- Before touching SRS components, disable system per manufacturer procedure (disconnect negative battery terminal and wait specified time).
- Perform a visual inspection of steering wheel, airbag connector, and harness for damage or corrosion.
- Reconnect battery if required by test equipment and measure squib resistance at the driver airbag connector and at the SRS module connector; compare to Land Rover specification. Do not short squib wires to battery.
- Check continuity from the squib pins to the SRS module; isolate any open or high-resistance sections (clock spring, connectors).
- Probe for short to ground or B+ in the squib circuit using a controlled method (manufacturer-recommended tests) — do not attempt to simulate deployment.
- If clock spring shows intermittent or open circuit, replace clock spring and retest.
- Repair or replace damaged wiring/connectors and clean/secure terminals. Replace squib or driver airbag only if resistance and other tests indicate a failed inflator.
- If wiring and components test good, suspect SRS control module fault; verify module power/ground and communications before module replacement.
- After repairs, clear codes and perform SRS system self-tests. Confirm no related codes and that SRS lamp extinguishes. Follow any post-repair calibration or reset procedures.
Likely causes
- Damaged clock spring causing intermittent or open circuit to driver squib
- Corroded/loose airbag connector at the steering wheel
- Short to ground or battery at the squib wiring from chafing
- Squib resistance outside manufacturer specification (failed squib)
- Faulty airbag control module or internal driver circuit fault
Fault status
Status
Stored when the SRS control module detects an electrical fault in the driver airbag stage 2 deployment circuit (open, short, excessive resistance, or module/internal driver fault).
Repair difficulty: Medium
Diagnostic time: 1–3 hours
