On-Board Diagnostics (OBD)

What is On-Board Diagnostics (OBD)?

OBD is a feature in vehicles that monitors and processes diagnostic information through a network of sensors connected to the controller area network (CAN), which acts as the vehicle’s central processing unit. This system provides a comprehensive overview of the vehicle's health, facilitating efficient problem diagnosis and offering valuable insights for fleet managers seeking to optimise fleet performance and reliability.

On-board diagnostics (OBD) refers to the integrated system in vehicles which monitors and communicates key aspects of their performance and condition. Using a network of sensors, the OBD system detects and diagnoses potential issues, allowing for timely repairs. This capability is especially important in fleet management, offering several advantages.

How does OBD Work?

The OBD system continuously monitors data from various sensors throughout the vehicle, comparing these readings to predefined boundaries. When a sensor detects a deviation from the expected range or identifies a fault, the OBD system generates a diagnostic trouble code.

This data is transmitted to the vehicle's onboard computers through the CAN, which then processes the information. The trouble codes help distinguish specific issues or malfunctions within the vehicle. Fleet managers can use specialised tools to access and interpret these codes in a digestible format, resulting in quick identification and resolution of problems.

The Benefits of OBD in Fleet Management

  • Enhanced vehicle performance: OBD systems provide fleet managers with detailed insights into engine performance and fuel efficiency. This data helps identify inefficiencies, enabling measures to reduce fuel consumption and improve overall vehicle performance.

  • Proactive maintenance: With real-time data on vehicle performance and faults, OBD systems support a proactive maintenance approach. By detecting issues early on, fleet managers can minimise downtime and avoid costly repairs while keeping vehicles in optimal condition.

  • Emissions compliance: Staying ahead of stringent emissions regulations is vital for fleet managers. OBD systems allow for detailed analysis of emissions data, ensuring that fleets comply with regulatory standards and avoids potential fines.

  • Improved driver behaviour: OBD systems monitor driver behaviour, including speeding, harsh braking, and rapid acceleration. This data enables fleet managers to implement targeted driver training programs, promote safer driving habits, and reduce the risk of accidents.

OBD Tools from MICHELIN Connected Fleet

OBD systems offer invaluable actionable insights into both the performance of individual vehicles and the overall health of fleets. By analysing data from their vehicles, fleet managers can gain a comprehensive view of fleet performance and identify areas for improvement, thereby increasing safety, efficiency, and cost control.

At MICHELIN Connected Fleet, we recognise the critical value of these insights. That’s why we’ve developed advanced fleet management solutions which integrate OBD hardware with specialised software. Our tools provide fleet managers with the data needed to make informed decisions and optimise fleet operations.
