If your scan tool displays B0097, your vehicle’s Supplemental Restraint System (SRS) has detected that the Right Frontal Restraints Sensor is not operating within its expected performance parameters.
Unlike an open or short circuit fault, a performance code means the sensor is communicating, but the Airbag Control Module (ACM) has determined its signals are implausible, intermittent, or outside the expected operating range.
The right frontal impact sensor helps determine when the vehicle has experienced a collision severe enough to deploy the front airbags and seat belt pretensioners. If its readings are unreliable, the ACM may disable portions of the SRS and illuminate the Airbag Warning Light.

Note: B0097 is a manufacturer-specific extension of the frontal restraint sensor family. While the exact wording varies by automaker, it generally indicates a performance or plausibility fault involving the Right Frontal Restraints (Impact) Sensor rather than an airbag deployment loop. Always verify the manufacturer-specific service information for your vehicle.

What Does B0097 Mean?
The B0097 code indicates the Airbag Control Module (ACM) has determined the Right Frontal Restraints Sensor is not operating within expected specifications.
Rather than detecting a simple electrical fault, the ACM compares sensor inputs against programmed values. If the sensor reports inconsistent or implausible data, the ACM stores B0097.
The monitored system typically includes:
- Right front impact sensor
- Sensor wiring harness
- SRS connectors
- Airbag Control Module
- Front bumper and radiator support mounting points

Symptoms of B0097
Common symptoms include:
- Airbag Warning Light illuminated
- “Service Airbag” or “SRS Fault” message
- Stored B0097 diagnostic code
- One or more airbags disabled
- Additional SRS diagnostic trouble codes
- Normal engine and transmission operation
Common Causes
Faulty Right Front Impact Sensor
Internal electronic degradation can cause inaccurate sensor readings.
Intermittent Wiring Fault
Damaged wiring may cause:
- Intermittent communication
- Voltage fluctuations
- Unstable sensor signals
Collision Damage
Minor front-end collisions can affect:
- Sensor alignment
- Mounting brackets
- Internal sensor calibration
Corroded or Loose Connector
Poor electrical contact may create intermittent communication errors.
Improper Previous Repairs
Previous body repairs may result in:
- Incorrect sensor installation
- Aftermarket sensors
- Improper wiring repairs
- Loose mounting hardware
Airbag Control Module Failure
Although uncommon, an internal ACM fault can incorrectly interpret sensor performance.
How Serious Is B0097?
Extremely serious.
If the ACM cannot rely on crash sensor information:
- Airbag deployment timing may be affected.
- Seat belt pretensioners may not activate properly.
- Occupant protection during a frontal collision may be reduced.
The SRS warning light should never be ignored.
Can You Drive With B0097?
Mechanically, yes.
From a safety standpoint, no.
The vehicle will generally drive normally, but portions of the Supplemental Restraint System may be disabled until repairs are completed.
How to Diagnose B0097
1. Scan the SRS Module
Use a professional scan tool capable of reading manufacturer-specific SRS codes and subfault information.
2. Inspect the Right Front Impact Sensor
Check for:
- Physical damage
- Loose mounting
- Bent brackets
- Water intrusion
3. Inspect Wiring and Connectors
Inspect for:
- Broken wires
- Corrosion
- Loose connectors
- Pinched harnesses
4. Verify Sensor Operation
Using manufacturer-approved diagnostic procedures, verify:
- Sensor communication
- Supply voltage
- Ground integrity
- Live sensor data
Never use a powered test light or directly probe airbag circuits.
5. Inspect Previous Collision Repairs
Verify:
- OEM sensor installation
- Proper mounting location
- Correct harness routing
- No structural damage affecting the sensor
Common Repairs
| Repair | Estimated Cost |
|---|---|
| Repair sensor wiring | $150–350 |
| Replace SRS connector | $100–250 |
| Replace right front impact sensor | $150–450 |
| Replace front wiring harness | $250–600 |
| Replace Airbag Control Module | $900–1,800 |
Common Diagnostic Mistakes
Many technicians replace the impact sensor without checking:
- Connector corrosion
- Sensor mounting alignment
- Wiring continuity
- Previous collision repairs
A performance fault does not always mean the sensor itself has failed.
Vehicles Commonly Affected
B0097 may be encountered on vehicles from manufacturers including:
- Chevrolet
- GMC
- Cadillac
- Buick
- Ford
- Lincoln
- Toyota
- Honda
- Nissan
- Hyundai
- Kia
- Subaru
- Mazda
- Jeep
- Dodge
Manufacturer-specific diagnostics and sensor calibration procedures vary.
How to Prevent B0097
You can reduce the likelihood of B0097 by:
- Inspecting crash sensors after any front-end impact.
- Repairing damaged wiring promptly.
- Keeping connectors clean and dry.
- Using OEM-quality replacement sensors.
- Properly reinstalling front bumper components.
- Addressing SRS warning lights immediately.
Frequently Asked Questions
What causes B0097?
Common causes include a failing right front impact sensor, intermittent wiring, corroded connectors, collision damage, improper repairs, or an Airbag Control Module fault.
Is B0097 dangerous?
Yes.
An unreliable crash sensor may prevent proper airbag deployment during a frontal collision.
Can a minor collision trigger B0097?
Yes.
Even low-speed impacts can affect sensor calibration, mounting, or wiring.
Can I clear B0097 myself?
Yes.
However, unless the underlying fault has been repaired, the code will generally return during the next SRS self-test.
Will B0097 affect vehicle performance?
No.
The code only affects the Supplemental Restraint System and does not impact engine, transmission, steering, or braking performance.
Final Thoughts
The B0097 code indicates the Right Frontal Restraints Sensor is not performing within the parameters expected by the Airbag Control Module. Although the vehicle will typically continue to drive normally, unreliable crash sensor data can prevent the Supplemental Restraint System from deploying airbags correctly when needed.
Prompt diagnosis of the sensor, wiring, connectors, and previous collision repairs is essential to restore full occupant protection.
