Causes
- Open or short in sensor wiring harness (broken wire, chafing, pinched)
- Corroded or loose connector at the sensor or SRS control module
- Faulty left side restraints sensor (accelerometer or crash sensor)
- Poor ground or power supply to the sensor
- Previous airbag deployment or improper sensor replacement
- Water intrusion or physical damage to the sensor
Symptoms
- SRS/Airbag warning lamp illuminated on instrument cluster
- Side airbag(s) or seatbelt pretensioner may be disabled (diagnostic only)
- Stored B0092 in SRS control module freeze-frame and event history
- Possible intermittent SRS lamp blinking or related faults when turning vehicle
- No obvious drivability issues (engine/transmission usually unaffected)
What to check
- Read SRS module with a capable scan tool; record DTC, freeze frame, and live data for side sensors
- Verify if SRS lamp is ON and check for additional SRS codes
- Visually inspect left side sensor connector, harness routing (under-seat, B-pillar, door sill) for damage, corrosion, or water
- Wiggle test harness and connectors while monitoring live sensor data to reproduce fault
- Check continuity and resistance of sensor circuit to SRS module (refer to vehicle-specific wiring)
- Inspect grounds and battery condition; poor battery voltage or ground may cause faults
Signal parameters
- Sensor output type: typically low-voltage signal (pulse/voltage or resistance change) reported to SRS module
- Expected signal range: manufacturer-specific; generally within 0–5 V for voltage sensors or specific resistance values — compare to the opposite side
- Connector pin voltages: reference (ground), supply (if present), and signal — check for stable supply and ground
- Intermittent spikes or zero/constant values indicate open/short or failed sensor
- SRS module may expect wake-up communications or periodic sensor diagnostics
Diagnostic algorithm
- Read and record the DTC and any related codes with a capable SRS scan tool. Note freeze-frame and event data.
- Follow vehicle service manual safety procedures: disable battery negative terminal and wait the specified time (commonly at least 2 minutes) before touching SRS components.
- Visually inspect the left side sensor and harness (under seat, door sill, B-pillar). Look for physical damage, corrosion, water, or signs of prior work.
- Reconnect battery, clear codes, and use live data to monitor the left side sensor while performing a wiggle test of the harness and connector to try to reproduce the fault.
- With ignition off and battery disconnected, measure continuity and resistance of the sensor circuit back to the SRS control module connector. Compare values to the opposite side sensor or to service manual specs.
- Inspect and test connector pins for corrosion, bent pins, or poor mating. Clean or repair connector as needed; perform a secure reconnect and retest.
- If wiring and connectors check good, swap the left sensor with the corresponding right sensor (if identical and vehicle procedures allow) to see if the fault follows the sensor. If fault moves, replace sensor.
- If fault remains on left side after replacing sensor, check SRS control module inputs, grounds, and module connector. Consult vehicle-specific wiring diagrams and module testing procedures.
- After repairs, clear codes and verify that the SRS lamp goes out and no related DTC returns. Perform full system self-test per manufacturer procedure.
- If uncertain or airbag components were deployed/previously repaired, recommend certified SRS technician or dealer for module reprogramming or advanced diagnostics.
Likely causes
- Damaged wiring under door sill, seat, or B-pillar causing intermittent/failed signal
- Connector pin corrosion or bent pins at sensor or harness mating connector
- Sensor failed due to impact, moisture, or age
- Loose chassis/negative ground affecting sensor circuit reference
- Control module software or internal fault reporting incorrect sensor status
Fault status
Status
Fault detected in left side restraints sensor #2 circuit. SRS control module logged B0092 and illuminated the airbag/SRS warning lamp. Side airbag/pretensioner functionality may be inhibited until the fault is resolved.
Repair difficulty: Medium
Diagnostic time: 0.5–2 hours
