B0092 — Side Impact Sensor Circuit Fault (Restraints System)

Severity: high Drive with care, to a shop

What B0092 means

The SRS control module continuously monitors the side impact sensors and checks their circuits for integrity. B0092 means it detected an open, short, out-of-range resistance or lost signal in a side restraint sensor circuit (usually described as the right side, though some references mix it up with the left sensor). While the fault is present, the system may disable some airbags or curtains.

Symptoms

  • Airbag/SRS warning light on
  • Passenger airbag indicator behaving oddly
  • Possible disabling of side airbags or curtains on one side
  • Warning light stays on after key-on

Possible causes

  1. Faulty side impact sensor
  2. Open, short or poor connection in the sensor wiring
  3. Corroded or damaged connector (in the door, pillar or under the seat)
  4. Wiring damaged during body, door or seat work
  5. Fault inside the SRS control module
  6. Stored code left over from a previous collision or repair

How to diagnose

  1. Scan all SRS codes with a tool that supports airbag systems and note the freeze frame data
  2. Inspect connectors and harness near the sensor, in the doors and pillars, for water, corrosion and chafing
  3. Ask about recent work: seat removal, trim, door or body repairs
  4. Disconnect the battery and wait per the manufacturer's procedure, then check the sensor and module connectors
  5. Measure circuit resistance against the spec in the service manual, and check for shorts to ground or voltage
  6. Substitute a known good sensor or use a manufacturer-approved test method to see if the code clears
  7. Clear the code and check whether it returns

Common fixes

  • Replace the faulty side impact sensor
  • Repair the wiring harness and replace damaged connectors
  • Clean and secure connector terminals
  • Repair or replace the SRS module and program it as required

B0092 on different brands

GM
On GM vehicles, references link this code to a side impact sensor circuit or the passenger presence system, so check the service information for your exact model.

Questions and answers

Can I drive with B0092?

Yes, but side crash protection may be incomplete. Do not put off diagnosis for long.

Why is my airbag light on?

The SRS module found a fault in a sensor circuit and is warning that the system may not work as intended.

What most often causes B0092?

Usually a poor connector contact or damaged wiring, then the sensor itself. The SRS module fails less often.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
