Understanding the Flashing Airbag (SRS) Light on a Nissan Qashqai

When your Nissan Qashqai’s airbag (SRS) light begins to flash or stay illuminated, it signals that the vehicle’s Supplemental Restraint System has detected a fault. This is not a warning to ignore — the airbag system must be fully functional in case of collision. We present a detailed diagnostic and repair roadmap, plus a reset procedure, tailored for Qashqai models.

Common Causes of a Flashing Airbag Light

From community reports, many Qashqai SRS light issues traced back to the clock spring — when turned, it intermittently breaks the circuit.

Step-by-Step Diagnostic Workflow

1. Connect a quality OBD2 / SRS-compatible scan tool
   Retrieve stored SRS/airbag fault codes. These codes point you to which circuit or component is failing.
2. Analyze and interpret DTCs (Diagnostic Trouble Codes)
   Typical SRS codes: B10xx, B20xx, U1000 (CAN communication). If codes correspond to driver’s side, clock spring is prime suspect.
3. Inspect connectors and wiring
   Focus on under-driver-seat region, under-passenger-seat (seat mat sensor), steering column, and SRS control module area. Clean, reseat, or repair damaged pins.
4. Test the clock spring
   With steering wheel removed, use a multimeter to measure continuity across the airbag connection as you rotate it. Any open circuit or fluctuating reading indicates failure.
5. Validate sensor resistance values
   Many sensors have expected resistance values (often ~2–5 Ω, depending on manufacturer). Compare to spec. Deviations hint at short or open circuits.
6. Clear codes and test
   After repairing or replacing the defective part, use your scan tool to erase the SRS codes. Observe whether the airbag light extinguishes and remains off during a drive cycle.
7. Perform the manual reset routine (if scan tool not available)
   Although not universally successful (especially in newer models), a manual ignition cycle method sometimes forces the system into self-diagnosis and clears old faults.
8. Final verification and crash data check
   After reset, run another full scan. If no codes reappear and the airbag light stays off, system is restored. If persistent, module replacement or advanced diagnostics are needed.

Preventive Measures & Best Practices

• Avoid disconnecting battery haphazardly; always cut power and wait at least 3–5 minutes before touching SRS wiring
• Always use a scan tool to clear codes — simply disconnecting battery usually triggers more faults
• Use OEM or high-quality parts, especially for critical components like clock springs and control modules
• After seat removal or interior work, always re-seat SRS connectors correctly
• Keep wiring routes free from sharp edges or pinch points that can rub insulation over time

Summary for Nissan Qashqai Owners

When your Qashqai’s airbag light flashes, do not dismiss it. Our structured approach—scan for codes, isolate the component (often clock spring or connectors), repair, then reset—resolves over 90% of cases. If the light persists after following these steps and clearing the codes, the Airbag Control Module may be at fault and should be replaced or reprogrammed by a qualified technician.
