Hey, good afternoon! This is Clay at Clay’s Acing Auto Repair and Clay Motion in Grand Rapids, Michigan. Today I want to address a common issue faced by Jeep Wrangler owners that can also affect Jeep Liberty, Jeep Commander, and Jeep Grand Cherokee models. If you find your airbag light coming on and receive error codes such as B156 and B1C4E, then this video is for you.
The original code I had was B1C4E, and I intentionally triggered B1B56 to demonstrate what happens if certain wires break. Let’s dive into the solution for this issue. First, I’m going to show you how to identify and address the problem code B1C49. This might not be the exact problem you’re facing, but it’s worth checking just in case. I’ll pop the code up on the scanner to help you troubleshoot it.
To access the affected area, I removed two rivets at the front and two at the back of the seat base, and then carefully separated the upper b-pillar plate. This allowed me to inspect the wiring harness and identify potential causes of the issue. Once I had the seat removed, I used a t45 tool to address the seat belt buckle pre-tensioning problem.
Upon closer inspection, I discovered that the track had clipped the wires within the seat, causing them to break. Now, to fix this, you have the option of either replacing the seat belt buckle entirely or attempting to repair the wires. I recommend soldering the wires together if you choose the repair route. However, in this case, I opted to remove the seat, flip it over, and address the issue by fixing the broken wires and possibly installing a new seat belt buckle.
Ultimately, if you encounter a similar issue and have the necessary tools and skills, you may attempt to repair the wires yourself. However, for the purpose of this demonstration, I decided to remove the seat and address the issue more directly. Remember, troubleshooting automotive problems often requires a combination of technical know-how and common sense.
If you’re experiencing a similar issue, I hope this video provides some valuable insight. Feel free to reach out with any questions or clarifications. Remember, if anyone else can do it, you can do it too. Have a great day!
