What is B0068?

DTC B0068 refers to a specific diagnostic trouble code related to airbag systems, indicating a fault in the airbag sensor circuit. This code generally means that the airbag control module has detected a malfunction in the sensor that monitors the status of the airbags. The airbag system is critical for passenger safety, deploying in the event of a collision to protect occupants. When this code appears, it signals potential issues with the airbag deployment system, which may be caused by faulty wiring, a malfunctioning sensor, or issues with the airbag control module itself. In practical terms, if this code is present, the airbag warning light may illuminate on the dashboard, and the airbag system may become inactive, rendering it unable to deploy during an accident. This could lead to serious safety implications. Car owners should address this issue promptly to ensure the safety features of their vehicle are fully operational. Common vehicles affected by this code include the 2010-2018 Ford Focus, 2011-2017 Hyundai Sonata, and various models from Toyota and Honda. Ignoring this code could mean risking passenger safety in the event of a crash, making it crucial for drivers to seek professional diagnostics and repairs as soon as the code is detected.

Symptoms

Common symptoms when B0068 is present:

  • The airbag warning light stays on, indicating a fault in the airbag system and potentially disabling airbag deployment.
  • Reduced functionality of the airbag system, which may result in the airbags not deploying in a collision, compromising safety.
  • Inconsistent behavior of dashboard indicators, such as flickering lights or failure to illuminate, suggesting electrical issues.
  • Possible diagnostic scanner errors, where multiple codes related to the airbag system might appear, indicating a broader issue.
  • Unusual noises or clicking sounds from the steering column or dashboard, potentially indicating wiring issues or a failing sensor.

Possible Causes

Most common causes of B0068 (ordered by frequency):

  1. The most common cause is a faulty airbag sensor, which is responsible for detecting crash forces; this accounts for approximately 50% of cases.
  2. Second, damaged or corroded wiring in the airbag system can lead to intermittent faults, affecting the circuit's integrity.
  3. Improper installation of aftermarket accessories, such as steering wheel covers or custom steering wheels, can disrupt the airbag circuit.
  4. Less common but serious causes include a malfunctioning airbag control module, which may need to be replaced to restore functionality.
  5. A rare cause could be a software glitch within the vehicle’s onboard computer systems, which may require a software update from the manufacturer.
