What it means

B0098 is the generic code for a fault in the Right Side Restraints Sensor 3 circuit or signal. The restraint control module (airbag ECU) runs self-tests on its crash and impact sensors, and it set this code because the sensor's signal, wiring or communication was missing, out of range or implausible. The exact sensor location and type (for example a door, pillar or seat-area sensor) depends on the make, model and equipment, so confirm it from the vehicle's wiring information.

Symptoms

Airbag or SRS warning light on the dashboard
Warning light stays on after restarting the car
Right-side airbags or belt pretensioners may be disabled or may not deploy in a crash
Fault may return soon after being cleared
Possible related restraint codes stored for other sensors or the passenger side

Possible causes

Low system voltage or poor earth connection affecting the restraint systemrare

How to diagnose

Read all stored codes and freeze frame data from the restraint system and note whether B0098 is current, stored or intermittent, and whether other restraint codes appear with it.
Check the vehicle's wiring information to find where Sensor 3 is on the right side for this model.
Check the battery is healthy and its voltage is stable, then follow the manufacturer's safe procedure for isolating the restraint system before touching any connectors.
Visually inspect the sensor, its mounting and its connector for damage, corrosion, moisture, bent pins or signs of accident repair.
Inspect the wiring from the sensor to the control module for chafing, pinching or poor repairs, especially through door shuts and under-seat areas.
With the system isolated and following the manufacturer's procedure, check the circuit's resistance, continuity and insulation as specified. Never apply test voltages to airbag circuits.
Wiggle-test the harness and connector while monitoring live data for the sensor to find intermittent faults.
Clear the code, restore the system and road test, then recheck for the code to confirm the repair.

How to fix

Clean, reseat or replace the damaged or corroded connector or terminals.
Repair or replace the damaged wiring section using the manufacturer-approved method.
Replace the faulty right-side sensor and make sure it is fitted correctly in the specified position.
Repair water ingress or damage around the sensor location, and correct any previous poor repair.
Replace or reprogram the restraint control module only if the manufacturer's diagnosis confirms it is faulty, including any required coding.

Can I keep driving?

High severity

The car may still drive normally, but the right-side restraints may not work properly in a collision, so limit driving and get it inspected promptly. Avoid carrying passengers on the right side until it is repaired if you must drive.
