Factors Responsible for Airbag Failure in Land Rovers
Airbag system failures on Land Rover and Range Rover are among the more common safety-related diagnostic calls we get at Foreign Automotive. The supplemental restraint system (SRS) is complex — multiple airbags front and side, seatbelt pretensioners, crash sensors at multiple locations, and a central control module that monitors everything. When the SRS warning light comes on, it has to be diagnosed and fixed promptly: in a crash, a disabled airbag system means real injury risk. This guide covers the most common causes of SRS faults on Land Rover platforms.
Common Causes of SRS Faults
- Seat occupancy sensor failure. The front passenger seat has an occupancy sensor that tells the system whether to deploy the passenger airbag in a crash. The sensor fails over time — particularly on cars where the passenger seat sees heavy use.
- Clock spring failure. The clock spring is the spiral conductor that carries the driver airbag signal through the steering column. Years of steering wheel rotation eventually break the internal conductors.
- Seatbelt pretensioner faults. Pretensioners use small pyrotechnic charges to retract the belt in a crash. The signal wiring to each pretensioner can develop intermittent connections, triggering SRS warnings.
- Side impact sensor faults. Sensors mounted in the doors and B-pillars detect side impacts. Water intrusion or corrosion at the connectors causes intermittent faults.
- SRS control module faults. Less common but real — the central module itself can fail, requiring replacement and re-coding.
Why Independent Specialists Matter
SRS work isn't something to take to a generic shop. Reading and clearing airbag codes requires the proper diagnostic equipment (Jaguar Land Rover SDD or Pathfinder in our case), the parts knowledge to identify the correct OEM replacement, and the procedural discipline to clear codes properly without leaving residual faults. At Foreign Automotive, we diagnose SRS issues across the Range Rover, Range Rover Sport, Discovery, Defender, Evoque, and Velar lines with the right tools.
