Causes

Damaged or chafed wiring harness that has contacted a battery positive circuit or constant 12V supply
Corroded, pushed-back, or damaged airbag connector making intermittent contact with positive voltage
Faulty or shorted right front airbag (squib) or seat belt pretensioner
Aftermarket electrical equipment incorrectly tied into vehicle constant power circuit
Faulty SRS control module or internal diagnostics error

Symptoms

SRS / airbag warning lamp illuminated on dash
Right front airbag disabled (may be reported by service tool)
Possible stored SRS fault codes and freeze frame data
In some cases seat belt pretensioner may be disabled or a separate related fault logged
No airbag deployment for the affected side until repaired

What to check

Read and record all SRS codes and freeze-frame data with a compatible scan tool
Confirm battery voltage is within normal range and stable before diagnostics
Visual inspection of right front airbag connector, wiring loom, seat harness, and door pillar areas for damage or pinched wiring
Inspect for aftermarket devices or splices tied into constant 12V circuits near the right front wiring
Check connector pins for corrosion, bent pins, or pushed-back insulation
Measure continuity/resistance of the airbag squib with battery disconnected (follow safety steps below)

Signal parameters

With ignition OFF and battery disconnected, expected squib resistance typically low (commonly ~2–6 ohms for frontal squibs) — manufacturer values vary
If circuit is shorted to battery, voltage at the squib feed pin (with harness connected and ignition ON) may read near battery voltage (~12 V) when it should be pulled low or not present
Open-circuit (infinite ohms) indicates connector/disconnection or cut wiring; extremely low near 0 ohms to chassis or battery positive indicates a direct short
SRS module diagnostic flags will show short-to-battery type fault and may identify circuit/connector location in freeze-frame

Diagnostic algorithm

SAFETY FIRST: Disable SRS power. Disconnect negative battery terminal and follow manufacturer wait time (typically several minutes) to allow SRS capacitors to discharge. Use anti-static precautions and follow airbag handling procedures.
Read and log all SRS codes and freeze-frame data with a manufacturer-level scan tool; note any additional related codes.
Perform a careful visual inspection of the right front airbag harness from the SRS module to the airbag/pretensioner: check door hinge area, seat belt anchor, seat tracks and connector areas for chafing, pinching, or aftermarket splices.
Inspect the right airbag/pretensioner connector pins for corrosion, pushed-back insulation, or evidence of battery positive contact. Repair or replace damaged connectors.
With battery still disconnected, measure the resistance of the right squib circuit at the connector. Compare to manufacturer specification (typical frontal squib ~2–6 ohms). If resistance is near 0 ohms to battery positive or chassis, suspect short; if infinite, suspect open circuit.
Isolate sections of harness: disconnect the right airbag connector at the module and at the SRS module harness connector to determine whether the short is in the wiring or internal to the module. Check for continuity between the squib feed and battery positive to locate the short.
If short is localized to a wiring section, repair using correct SRS repair methods (replace damaged sections, proper terminal replacement, use manufacturer-approved connectors and crimps).
If the squib itself measures out of specification, replace the airbag/pretensioner assembly per procedure.
If wiring and squib check good and short persists only when connected to the SRS module, suspect module fault — confirm with wiring diagram and manufacturer tests before module replacement.
After repair, reconnect battery, clear codes with scan tool, and perform SRS self-test and final verification driving checks per manufacturer. Ensure no related codes return.

Likely causes

Chafed wiring at door hinge/seat area contacting constant 12V feed
Contaminated/corroded squib connector that is shorting to battery positive
Shorted right-front airbag squib or pretensioner element
Incorrect repair or aftermarket accessory connected to constant battery feed in the SRS circuit
Faulty SRS unit or connector pin providing constant battery to the squib circuit

Fault status

⚠️ Status

Right front airbag circuit - short to battery detected. SRS light on; right-side airbag deployment is inhibited until the fault is repaired.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 1.0-3.0 hours
