Webfleet vehicle diagnostics

Vehicle diagnostics relies on sensors in a vehicle which monitor health signals like engine temperature, tyre pressure and battery health. If an issue is detected, the sensor sends a signal via the Controller Area Network (CAN), the vehicle’s internal messaging system. Diagnostics software in telematics devices reads CAN messages remotely, identifies the problem and displays it in a compre­hensible way for fleet operators via the digital platform.

The Webfleet interface has a dedicated diagnostics section where managers can visualise:

• DTCs, CAN signals, MILs and Tell Tales.
• Fault event category, date and time, triggering position, distance since trigger, last event status and number of occurrences.

The Webfleet Vehicle Diagnostics feature allows you to set up alert notifications and smart notifications.

Receive alerts about the detection of DTCs, CAN warnings and check engine lights (MIL), marked with corresponding severity levels.

Smart notifications take alerts a step further by allowing you to configure rules for when and how you receive updates. Set custom parameters based on event type, vehicle lists, users to notify and even follow-up rules.

As a manager or driver for a transport fleet, here’s what you should expect from vehicle diagnostic tools:

• A user-friendly interface — so you can interpret data easily and take action.
• Remote capabilities — so back office can keep track of vehicle status from a distance.
• Events display — to respond to issues correctly, you need to know the specific event, event type and date and time.

By booking Webfleet Vehicle Diagnostics, you get greater visibility with additional features. Including:

• Advanced event details — displaying severity, frequency and status.
• Fault history — for tracking recurring issues over time, aiding long-term maintenance strategies and root cause analysis.
• Customisable alerts — notifications for DTC, CAN warnings and MIL based on three severity levels (alarm, warning, notices).
• Smart notifications — an extra layer of configurable alerts and follow-up rules.

Remote diagnostics allows fleet managers to take corrective measures towards vehicle issues from anywhere — no need to wait to access the vehicle physically for health checks.

By proactively addressing maintenance needs before they become major issues, you reduce unexpected repair time that could disrupt and delay your service. That means increased uptime and vehicle availability.

Remote vehicle diagnostics also increases safety levels. Spotting and fixing vehicle faults leads to fewer incidents, protecting drivers and other road users.

Diagnostic technology can also protect your revenue. With automatic alerts about faults, fleet managers can call upon maintenance professionals promptly to make smaller repairs before an expensive breakdown occurs. Plus, well-­main­tained vehicles run more smoothly, consume less fuel and have a longer lifespan.

The most important consideration when selecting a vehicle diagnostics system is compatibility. It needs to support the makes and models of your fleet vehicles. Webfleet’s system is designed to work with both OBD-II and CAN bus technologies, making it compatible with a wide range of vehicle types and fleet setups.

Integration with fleet management systems is also key for data sharing and comparison across other fleet domains to boost operational efficiency. Webfleet’s diagnostics system is fully integrated into its management platform, allowing you to visualise fault events and compare vehicle conditions and activity across your entire fleet — so you get the most out of every data point.

On-board diagnostics systems allow fleet operators to take smaller, less costly maintenance actions earlier. Detecting issues before they become major problems enables proactive service scheduling and means less time off-road whilst making these minor repairs.
