Subaru Forester · 2015–2018
The Occupant Detection System sensor mat wiring harness in the front passenger seat cushion develops an unstable electrical connection (decreased contact pressure between terminals). This causes the SRS airbag warning light to illuminate and the passenger frontal airbag to deactivate even when the seat is occupied — a genuine safety defect because the airbag may not deploy in a crash. Subaru issued NHTSA safety recall 19V701 (Subaru campaign WUM-98) covering roughly 366,000 Foresters built January 20, 2015 through August 1, 2017, to inspect/replace the ODS sensor mat harness. Owners widely report the fault recurring after the recall repair, and dealers frequently attribute recurrences to seat 'water damage' and deny goodwill, leaving owners to pay out of pocket.
Common Symptoms
- SRS/airbag warning light illuminated
- Passenger airbag OFF indicator stays lit with an adult passenger seated
- Airbag ON/OFF indicators cycle or behave erratically
- Intermittent fault that comes and goes with bumps or seat load
How to Fix
Under safety recall 19V701, dealers inspect and replace the ODS sensor mat harness free of charge — verify eligibility by VIN first. Out of recall, the fix is replacing the occupant detection sensor mat / harness in the seat bottom (Subaru part e.g. 64084SJ100); recurrent or severe cases require replacing the seat cushion assembly.

Frequently asked questions
What does B1760 mean?

A Subaru-specific airbag/SRS code, documented in Subaru service manuals and service bulletins (notably 2014-2018 Forester, and models including Impreza, Crosstrek, and WRX). The Occupant Detection System (ODS) control module has detected an abnormal signal from the front passenger seat cushion sensor mat or its circuit. Because the ODS decides whether the passenger airbag arms, this code lights the airbag warning lamp and typically disables the passenger airbag as a fail-safe — a genuine safety concern that should be repaired promptly.

The most common causes of B1760 are: Liquid spilled onto the passenger seat cushion, or rainwater from an open window, reaching the sensor mat, High humidity or moisture intrusion in the seat upholstery, Poor contact or corrosion at the connector between the sensor mat and ODS control module, Damaged or pinched sensor mat harness under the seat, Physically damaged sensor mat from heavy loads, child seats, or seat removal, Faulty occupant detection control module.
