Overview

B0098 indicates a fault in the right‑side restraints sensor 3 circuit of the Supplemental Restraint System (airbags), often due to wiring or sensor failures causing SRS warning lamp illumination and potential airbag disablement.

Common Symptoms

Airbag/SRS warning lamp illuminated on dashboard
Stored B0098 code in airbag/SRS module
Side‑airbag protection may be inactive
Potential inability of side airbags to deploy during a collision

Most Common Causes

Open or short in sensor 3 circuit high

Wiring break, short to ground/battery, or internal sensor fault often triggers the code.

Corroded or loose connector medium

Moisture or poor connection at sensor plug can cause intermittent or constant faults.

Faulty restraints sensor (Sensor 3) medium

Sensor internal failure due to age or impact may be root cause.

Airbag/SRS control module communication or firmware issue low

Less common but can misinterpret good sensor data or lose communication.

Diagnostic Steps

Verify and record B0098 code using a professional scan tool with SRS capabilities

Expected: B0098 present and SRS warning lamp on

Interpretation: Confirms code exists before beginning diagnostics
Visual inspection of right‑side impact sensor wiring and connector

Expected: Check for damaged wires, chafing, corrosion, loose pins

Interpretation: Damage or corrosion here often indicates cause
Measure sensor circuit resistance and reference voltage at connector

Expected: Reference voltage (often ~5V) and valid resistance per OEM spec

Interpretation: Out‑of‑range values indicate open/short circuit or defective sensor
Continuity check from sensor to SRS module

Expected: Continuity without high resistance

Interpretation: High resistance or open circuit confirms wiring issue
Check SRS control module communication and firmware version

Expected: Module responds normally, firmware matches vehicle VIN

Interpretation: Communication or mismatch may require reflashing or module replacement

Repair Solutions

Repair wiring harness or connectors medium

Estimated Cost: $50 - $300

Typical fix for open/short or corrosion; includes connector cleaning and wire repair.

Replace right‑side impact/airbag sensor 3 medium

Estimated Cost: $150 - $600

Replace sensor if internal fault confirmed; costs vary by make/model.

Reflash or replace SRS control module hard

Estimated Cost: $500 - $1200

Required if module communication or firmware issue confirmed; dealer or specialized tool often required.

Common Misdiagnoses

Avoid these common diagnostic mistakes:

Generic OBD scan showing only body code without SRS‑specific scan leading to misidentification of airbag control module fault

Frequently Asked Questions

Technical definition of B0098 OBD-II Code

The B0098 code stands for Right Side Restraints Sensor 3 Circuit Fault. This generally indicates an issue with the Sensors system.

Can B0098 cause engine damage?

This is a high priority issue. No direct impact on engine performance, but disables at least one side‑impact airbag and triggers SRS/Airbag warning lamp.

What happens when the B0098 code is active?

Drivers often report: Airbag/SRS warning lamp illuminated on dashboard, Stored B0098 code in airbag/SRS module, Side‑airbag protection may be inactive when this code is present.

What parts fail when B0098 is set?

This code is frequently triggered by: Open or short in sensor 3 circuit, Corroded or loose connector, Faulty restraints sensor (Sensor 3).

Repair cost breakdown for B0098

Expect to pay around $300 if the issue is a Repair wiring harness or connectors, but up to $1200 if the Reflash or replace SRS control module needs replacement.

Is the B0098 code specific to Honda?

B0098 is not specific to any one brand. It can appear on Ford, Dodge, Toyota, Honda, Jeep, and other vehicles.
