B0092 medium Severity

B0092: Left Side Restraints Sensor 2 (Subfault)

May illuminate airbag/SRS warning and can disable passenger supplemental restraint function

Overview

DTC B0092 indicates a fault in the supplemental restraint system sensor circuit, typically Left Side Restraints Sensor 2 or passenger presence system malfunction in GM vehicles, caused by sensor, wiring, or module issues

Common Symptoms

  • Airbag (SRS) warning light illuminated
  • Passenger airbag indicator abnormal behavior
  • Potential disablement of passenger airbag deployment

Most Common Causes

Faulty left side restraint or passenger presence sensor high

Codes point to sensor circuit malfunction within SRS system

Open/short or poor electrical connection in sensor wiring/harness medium

Common wiring fault noted in community and tech sources

Fault within SRS/Restraints control module medium

Module faults less frequent but possible

Diagnostic Steps

  1. Check for presence and history of code using professional scan tool
    Expected: B0092 present current or history
    Interpretation: Confirms need for SRS circuit diagnosis
  2. Perform visual inspection of connectors and wiring to left side restraint/passenger presence sensor
    Expected: No broken wires, corrosion, loose connectors
    Interpretation: Faulty connectors or wiring may be cause
  3. Measure reference and signal voltages at sensor with multimeter per manufacturer specs
    Expected: Appropriate reference voltage and continuity
    Interpretation: Abnormal readings indicate wiring/sensor fault
  4. Check stored sub-codes and perform component-specific resistance tests
    Expected: Normal resistance and sensor response
    Interpretation: Fail indicates specific component replacement
  5. If wiring and sensor test normal, evaluate SRS module operation and programming
    Expected: Proper module supply of reference and response
    Interpretation: Fault here suggests module service

Repair Solutions

Repair or replace faulty sensor medium
Estimated Cost: $100 - $400

Depends on vehicle and sensor complexity

Repair wiring harness and connectors medium
Estimated Cost: $50 - $250

Cleaning and securing connections often resolves code

Service or replace SRS control module hard
Estimated Cost: $300 - $900

Control module repairs often require dealer level equipment

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Generic airbag system faults such as unrelated crash sensor failures
