Code B1C28 Chrysler Description
The B1C28 diagnostic trouble code (DTC) is specific to Chrysler vehicles and indicates a fault with the left side seat thorax airbag squib 1 circuit. The term "squib" refers to the small explosive device that ignites to deploy the airbag in the event of a collision. When this code is triggered, it signifies that the airbag control module has detected a high resistance or an open circuit in the left thorax airbag squib, which is responsible for deploying the thorax airbag located in the driver's seat.
Common Causes of B1C28 Chrysler
- Damaged Wiring: Frayed or damaged wiring in the seat harness can lead to high resistance in the squib circuit.
- Corroded Connectors: Corrosion at the connectors can disrupt the electrical flow necessary for proper airbag deployment.
- Faulty Airbag Module: A malfunctioning airbag control module may incorrectly interpret the squib circuit's status.
- Seat Movement Issues: Frequent adjustments to the seat can cause wear and tear on the wiring, leading to faults in the squib circuit.
- Previous Collision Damage: Any previous accidents may have compromised the integrity of the airbag system, leading to this code being triggered.
Symptoms of B1C28 Chrysler
- Airbag Warning Light: The airbag warning light on the dashboard may illuminate, indicating a fault in the airbag system.
- Inoperative Airbag: The left thorax airbag may fail to deploy during a collision, posing a significant safety risk.
- Diagnostic Trouble Code: The presence of the B1C28 code when scanned with an OBD-II scanner.
- Intermittent Electrical Issues: Possible intermittent issues with the seat adjustments or other electrical components related to the seat.
- Increased Resistance in Circuit: A noticeable increase in resistance when testing the squib circuit, indicating a potential fault.
How to Fix B1C28 Chrysler
- Diagnostic Scan: Begin by using an OBD-II scanner to confirm the presence of the B1C28 code and check for any additional codes that may provide further insight.
- Visual Inspection: Perform a thorough visual inspection of the wiring harness and connectors associated with the left thorax airbag squib for any signs of damage or corrosion.
- Electrical Testing: Use a multimeter to test the resistance in the squib circuit. Compare the readings to manufacturer specifications to identify any abnormalities.
- Repair or Replace Components: Depending on the findings, repair any damaged wiring or connectors. If the airbag module is faulty, it may need to be replaced.
- Clear Codes and Test: After repairs are made, clear the diagnostic trouble codes and conduct a test drive to ensure the airbag system is functioning correctly and the warning light does not reappear.
Cost to Fix B1C28 Chrysler
The typical repair costs for addressing the B1C28 code can vary widely based on the specific issue found during diagnosis. On average, repairs could range from $150 to $600. This estimate includes parts such as wiring harnesses or connectors (which can cost between $50 and $200) and labor costs, which typically range from $80 to $150 per hour. The total labor time for diagnosing and repairing the issue may take 1 to 3 hours, depending on the complexity of the repairs needed. It is important to note that labor rates can vary significantly based on location, vehicle make and model, and engine type. In metropolitan areas or at dealerships, rates may be higher, while independent shops may offer lower rates. It is advisable to check local rates for a more precise estimate.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
