# B0099-96: Roll-Over Sensor - Component Internal Failure

This diagnostic trouble code (DTC) indicates an issue with the roll-over (or yaw rate) sensor, commonly tied to the airbag system to detect roll-over events. Here's a step-by-step guide to address this issue:

 

**Steps to Recalibrate the Roll-Over Sensor:**

 

**1. Use a High-End Scan Tool:**

- Ensure the scan tool supports SRS (Supplemental Restraint System) or ABS (Anti-lock Braking System) recalibration options.

**2. Navigate to the Recalibration/Configuration Menu:**

- Look for a section labeled "Recalibration" or "Reconfiguration" under the SRS or ABS menu.
- Check for the roll-over (Yaw Rate) sensor in the dropdown options.

**2. Follow On-Screen Instructions:**

- Start the recalibration process as per the scan tool's guidance.
- Ensure the vehicle is parked on a flat surface to avoid calibration errors.
- Complete the procedure as prompted.

**3. Verify Calibration Success:**

- If the recalibration succeeds, the B0099-96 code should clear automatically, and any associated dashboard light (e.g., airbag warning light) should turn off.

---

**What to Do If Recalibration Fails:**

**1. Retry the Procedure:**

- Attempt the recalibration process a few times. Calibration failures can occasionally occur due to minor interruptions or improper setup.

**2. Check for Other Issues:**

- Inspect the wiring and connections related to the roll-over sensor for damage or loose connections.
- Verify that the sensor itself has no visible physical damage.

**3. Replace the Sensor Module:**

- If recalibration consistently fails, the sensor may have an internal failure, and replacement is required.
- Use an OEM (Original Equipment Manufacturer) replacement to ensure compatibility and proper system functionality.

---

**Post-Replacement Recalibration:**

**After replacing the roll-over sensor:**

- Perform the recalibration process again to ensure the new sensor is correctly integrated with the system.
- Clear any residual codes using the scan tool.

 

If issues persist even after following these steps, professional diagnostic services may be required to rule out broader system faults.
