Second row right side airbag squib circuit malfunction.

Common symptoms

  • SRS warning lamp

Typical causes

  • RR seat side bag module
  • Wiring in seat rail
  • Prior collision damage

What scanner do you need?

Full-system scanner (engine, ABS, SRS, transmission, service resets)

Use live data and freeze frame to confirm the fault before replacing parts. ABS, SRS, and network U-codes usually require a full-system scanner.

  • Clear the code only after fixing the root cause
  • Check for related pending codes that point to a common issue
  • Verify battery voltage is above 12.4V before chasing sensor codes
