C0B83 is commonly reported in models like the 2016-2020 Ford Explorer, 2017-2020 Ford F-150, and various vehicles from the Ford family. Check for any recalls or Technical Service Bulletins (TSBs) related to your vehicle model.
How can I prevent C0B83 from happening again?
Regular maintenance, including checking brake system components and ensuring software updates are performed, can help prevent the C0B83 code from appearing. Additionally, consider using diagnostic tools like the GeekOBD APP to monitor brake system status.
What is C0B83?
The Diagnostic Trouble Code (DTC) C0B83 indicates a performance issue with the brake system control module. This code is often triggered when the brake system control module detects an inconsistency in its performance parameters, which could stem from wiring problems, software glitches, or issues with the brake pedal position sensor. For car owners, this code can manifest as a warning light on the dashboard, prompting concern over brake functionality. The brake system is vital for safety; thus, a malfunction can lead to diminished braking power or erratic brake behavior, which can be particularly alarming when driving. In vehicles such as the 2016-2020 Ford Explorer, the brake system control module plays a crucial role in ensuring that the brakes respond accurately to driver input. If you experience this code, it is essential to address it promptly, as ignoring it could lead to unsafe driving conditions. Regular maintenance checks and diagnostics using tools like the GeekOBD APP can help identify issues before they escalate, ensuring both safety and performance remain optimal on the road.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0B83 is present:
- Check engine light illuminated, indicating a fault in the brake system control module.
- Brake pedal feels soft or unresponsive during operation, which can lead to a sudden loss of braking ability.
- Unusual braking behavior, such as the vehicle lurching or jerking when applying brakes, indicating possible module malfunction.
- Increased stopping distance, which can be a significant safety concern, especially in emergency situations.
- Occasional loss of power to the brake assist feature, making it harder to stop the vehicle quickly.
Possible Causes
Most common causes of C0B83 (ordered by frequency):
- Faulty brake system control module (40% likelihood) - This is the most common cause and often due to internal failures or software issues within the module.
- Damaged wiring or connectors (30% likelihood) - Corroded or broken wires can disrupt the signal to the control module, leading to performance issues.
- Brake pedal position sensor malfunction (20% likelihood) - If this sensor fails, it can send incorrect signals to the control module, affecting braking performance.
- Software issues (5% likelihood) - Occasionally, updates or bugs in the vehicle’s software can trigger this code.
- Mechanical failure in the braking system (5% likelihood) - While rare, issues like a stuck caliper or worn brake pads can indirectly affect the control module's performance.
