Causes

Open or intermittent wiring between passenger airbag and airbag control module
Short to ground or short to battery (power) in the passenger airbag circuit
Corroded, damaged or disconnected connector under the passenger seat or at the airbag module
Faulty passenger airbag squib (inflator/igniter) or harness splice
Faulty occupant classification/seat weight sensor or its wiring (system dependent)
Faulty airbag control module or internal driver electronics

Symptoms

SRS/Airbag warning light illuminated on dash
Passenger airbag status may show OFF or unavailable
DTC B0417 stored (may be accompanied by other SRS codes)
Possible intermittent SRS lamp or lamp on after vehicle movement or seat position changes
Passenger airbag may be disabled until fault is repaired

What to check

Safety first: follow manufacturer SRS safety procedures before working on system. Disable battery and wait the manufacturer-specified time (commonly 90 seconds or more) before disconnecting SRS components.
Connect a diagnostic scan tool capable of reading SRS modules. Read and record stored DTCs, freeze frame and live data; note any companion codes.
Visually inspect passenger seat area, seat rails, connectors and harness routing for damage, corrosion, loose connectors, pin backouts or aftermarket modifications.
Inspect connectors at the airbag control module and passenger airbag module (dash / glovebox area). Ensure correct seating and retention of locking tabs.
With SRS power disabled, measure squib (inflator) circuit resistance and compare to specification. Check continuity of harness from module to passenger airbag connector.
Check for short to ground or battery by measuring resistance between each squib pin and vehicle ground/power with power removed.

Signal parameters

Typical passenger airbag squib resistance (vehicle-specific) commonly in the range ~0.5–5 ohms — consult OEM spec before replacing components
Open circuit: infinite/OL on ohmmeter between squib pins (indicates break/disconnected)
Short to ground: very low resistance between squib pin and vehicle ground (
Key ON (diagnostic) — airbag ECU should report circuit status via scan tool (OK / open / short / high resistance) — refer to live data values provided by scanner and OEM thresholds
Note: never apply battery voltage to squib for testing. Use only passive resistance/continuity checks with SRS power removed.

Diagnostic algorithm

Review vehicle service manual for B0417, SRS safety procedures, connector locations and component resistance specifications.
Disable SRS: disconnect negative battery terminal and wait manufacturer-specified time (commonly ≥90 seconds) or follow factory SRS disable procedure.
Use scan tool to read all SRS and related codes; record freeze-frame and any network/occupant classification codes. Note whether fault is constant or intermittent.
Visually inspect passenger seat, seat rails, and under-seat area for damaged wiring, pinched harness, loose or corroded connectors, aftermarket wiring or foreign objects.
With SRS power disabled, disconnect passenger airbag connector and measure resistance across the airbag squib pins. Compare value to OEM spec. If infinite, suspect open circuit; if extremely low, suspect shorted squib or short to ground.
Check continuity of each conductor between passenger airbag connector and airbag control module connector. Repair any open/shorted wires or damaged insulation; secure harness away from moving parts.
Inspect and test occupant classification/weight sensor and its harness (if applicable) — some systems will set passenger airbag circuit faults tied to the OCC sensor cluster.
Repair or replace damaged connectors, splices, harness sections, or the airbag module only with correct OEM parts and following safety precautions. Replace squib/airbag only when required and with correct replacement and disposal procedures after deployment.
Reconnect connectors, clear codes with scan tool, reconnect battery per procedure, and perform SRS system self-test. Verify the SRS lamp behaviour and re-scan for codes. If intermittent, perform wiggle tests while monitoring live data to reproduce.
If fault persists after harness and connector repairs, consider replacement or bench diagnostic procedures for airbag control module per manufacturer guidance; involve OEM tech support if needed.

Likely causes

Disconnected or corroded connector under passenger seat
Wiring chafed at seat rail or harness branch — open or intermittent connection
High resistance in squib or connector causing out-of-range resistance
Short to ground from pin damage or pin pushed into body sheetmetal
Faulty occupant classification module tied into passenger airbag circuit (if equipped)

Fault status

⚠️ Status

Stored when the airbag control module detects an open, short, high resistance, or circuit out-of-range condition in the front passenger airbag firing/monitoring circuit. Causes SRS warning lamp and may disable passenger airbag.

🟡 Repair difficulty: Medium
