What Is the “In-Vehicle Network Malfunction” Message?

The “in-vehicle network malfunction” message in a Mazda 3 indicates a problem with the vehicle’s network systems, which connect various electronic components such as the engine control module, transmission control module, and dashboard display. This warning light can be concerning, especially if it appears periodically or persists.

Possible Causes of the Malfunction

The underlying cause of the in-vehicle network malfunction can be difficult to determine without proper diagnostics. However, some potential reasons include:

• Loose or damaged wiring: Electrical connections within the vehicle’s network can become loose or damaged, disrupting communication between components.
• Faulty components: Individual electronic modules or sensors can malfunction, leading to communication errors on the network.
• Software issues: Outdated or corrupted software in the vehicle’s electronic control units can cause communication failures.

Dealer Inspection and Software Updates

If you see the “in-vehicle network malfunction” message, it is recommended to have your Mazda 3 inspected by a qualified mechanic. They can diagnose the issue using specialized equipment and perform necessary repairs. In many cases, software updates can resolve the problem.

Cost of Diagnosis and Repairs

The cost of diagnosing and repairing an in-vehicle network malfunction can vary depending on the specific issue. If the problem is simple, such as a loose connection, the repair may be relatively inexpensive. However, if more complex repairs or software updates are required, the costs can increase.

Possible Solutions

• Manual software updates: It is generally not recommended to install software updates manually, as this process can be complex and requires specialized tools. It is best to have updates performed by a dealership or qualified mechanic.
