B0108 is frequently seen in vehicles such as the 2015-2018 Honda Accord, 2013 Ford Fusion, and 2016 Chevrolet Malibu. Always check for any recalls or TSBs related to your specific model for more information.
How can I prevent B0108 from happening again?
Regular maintenance checks on your airbag system and wiring can help prevent issues like B0108. Ensure that any aftermarket modifications are compatible with your vehicle’s airbag system to avoid interference.
What is B0108?
The DTC B0108 indicates a high resistance issue in the airbag circuit, which is crucial for your vehicle's safety system. This code typically arises when the airbag control module detects an abnormal resistance level in the circuits connected to the airbags or seatbelt tensioners. The implications of this code are serious; it can lead to the airbag system being disabled, which means that in the event of a collision, the airbags may not deploy as intended. Commonly found in models such as the 2015-2018 Honda Accord, 2013 Ford Fusion, and 2016 Chevrolet Malibu, this code is often triggered by issues like damaged wiring, corroded connectors, or faulty airbag components. If your vehicle's airbag warning light is illuminated, addressing this code should be a priority for your safety. Not only does this code affect your vehicle's operational integrity, but it may also lead to failed inspections, increased insurance premiums, and significant repair costs if left unresolved. To understand and rectify the issue, it is recommended to utilize an OBD2 scanner, such as the GeekOBD APP, which can assist in pinpointing the exact cause and facilitate a more efficient repair process.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0108 is present:
- The airbag warning light illuminates on the dashboard, indicating a malfunction in the airbag system.
- You might notice that the seatbelt tensioners are not functioning properly, which can be felt as a lack of resistance during fastenings.
- In some cases, the vehicle may exhibit a chime or message indicating 'Airbag Fault' or similar warnings.
- There may be a noticeable delay in airbag deployment during tests, which can be confirmed through diagnostic tools.
- An increase in error codes related to the airbag system may be present when scanning with an OBD2 scanner.
Possible Causes
Most common causes of B0108 (ordered by frequency):
- The most common cause is damaged wiring, which is responsible for about 60% of B0108 cases. This can happen due to wear and tear or physical damage.
- A second cause is corroded connectors, which can disrupt the electrical flow and lead to high resistance. This is often overlooked during regular maintenance.
- Faulty airbag components such as the airbag module or sensors can account for around 20% of the issues, typically requiring replacement for resolution.
- Less common but serious causes include manufacturing defects in airbag systems, which may necessitate a recall or technical service bulletin (TSB).
- A rare cause could be interference from aftermarket modifications or installations, which might disrupt the integrity of the airbag circuit.
