DTC Code B1195 – What does this code mean?

<ul> <li><b>Air Bag Warning Light ON</b>: The air bag warning light illuminates on the dashboard, indicating a potential issue with the air bag system. This is often linked to a ground short in the right side front curtain air bag module.</li> <li><b>Right Side Front Curtain Air Bag Inoperative</b>: The right side front curtain air bag may not deploy in the event of a collision due to the ground short, compromising passenger safety.</li> <li><b>Diagnostic Trouble Code B1195 Stored</b>: The vehicle's onboard diagnostics system stores the DTC B1195, which specifically points to a ground short in the right side front curtain air bag module.</li> </ul>

<ul><li>The right side front curtain air bag module may be faulty, causing a ground short.</li><li>The harness for the right side front curtain air bag module could be open or shorted, disrupting the circuit.</li><li>Poor electrical connections in the right side front curtain air bag module circuit can lead to this error code.</li><li>A malfunctioning air bag sensor unit (air bag control module) might also be responsible for the issue.</li></ul>

<ul> <li><b>Initial Inspection</b>: Visually inspect the right side front curtain airbag module and its wiring for any obvious signs of damage, wear, or corrosion.</li> <li><b>Check Ground Connection</b>: Verify the ground connection of the right side front curtain airbag module. Ensure it is secure and free of corrosion.</li> <li><b>Measure Resistance</b>: Using a multimeter, measure the resistance between the ground wire of the airbag module and the vehicle chassis. The resistance should be close to zero ohms.</li> <li><b>Inspect Wiring Harness</b>: Inspect the wiring harness for any signs of short circuits, such as frayed wires or exposed conductors. Repair or replace any damaged sections.</li> <li><b>Check Airbag Control Module</b>: Verify the airbag control module for any signs of malfunction. This may involve using a diagnostic scanner to check for additional codes or anomalies.</li> <li><b>Perform Continuity Test</b>: Perform a continuity test on the wiring from the airbag module to the control module to ensure there are no breaks or shorts in the circuit.</li> <li><b>Clear DTC and Test Drive</b>: After performing the necessary repairs, clear the DTC code and conduct a test drive to ensure the issue has been resolved and the code does not reappear.</li></ul>

<p>The DTC code B1195 indicates a ground short in the right side front curtain airbag module. This is a <b>critical</b> issue as it directly affects the vehicle's safety systems.</p><ul><li>Immediate action is required to diagnose and repair the short circuit.</li><li>Failure to address this issue can result in the airbag not deploying during a collision, posing a significant risk to passenger safety.</li></ul>
