Instrument Cluster Repair for Trucks and Buses: Common Faults and Repair Options

Modern commercial vehicles rely on electronic instrument clusters to provide drivers with essential information about vehicle performance and system status. Speed, warnings, diagnostic information and communication with other control modules all pass through the dashboard display.

When faults occur, instrument cluster repair can often restore the unit without the need for full replacement.

At Remanufactured Parts Ltd we regularly carry out instrument cluster repairs for trucks, buses and other commercial vehicles, helping fleets restore dashboard functionality while avoiding the cost and delays associated with sourcing new units.

What Does an Instrument Cluster Do?

The instrument cluster acts as the vehicle’s information centre. It receives signals from multiple electronic control units across the vehicle and displays them to the driver through gauges, warning lights and digital screens.

In modern commercial vehicles the cluster is also connected to the wider vehicle CAN network. Because of this, faults within the cluster can sometimes affect other systems or trigger warning lights that appear unrelated to the dashboard itself.

When clusters begin to fail or behave intermittently, drivers may lose access to important vehicle information.


Common Instrument Cluster Faults

Over time, clusters can develop faults due to vibration, temperature changes, moisture ingress and general electronic wear.

Typical problems that require instrument cluster repair include:

• Blank or flickering displays
• Warning lights not functioning correctly
• Dashboard resets or intermittent power loss
• Communication errors with other control modules
• Backlight or display visibility issues
• Complete cluster failure

These faults may begin intermittently before becoming permanent if the cluster continues to deteriorate.


Volvo Instrument Cluster Repairs

One of the most common units we see in the workshop is the Volvo instrument cluster used in trucks and buses. These clusters are designed to operate reliably for many years, but like any electronic component they can eventually develop faults due to vibration, thermal cycling and environmental exposure.

Typical symptoms of Volvo instrument cluster faults include:

• Dashboard display failure
• Warning lights appearing incorrectly
• Communication faults with other vehicle systems
• Intermittent resets or loss of information on the display

In many cases these problems can be resolved through instrument cluster repair at component level, allowing the original unit to be restored rather than replaced.

For example, the Volvo instrument cluster repair is a unit we regularly support through our remanufacturing process.

Remanufacturing these clusters allows fleets to return vehicles to service quickly while reducing the cost associated with sourcing new electronic units.


When Instrument Cluster Faults Are Caused by Other Components

It’s important to remember that not all dashboard issues originate in the cluster itself. Because vehicle electronics are interconnected, faults in other components can sometimes appear as cluster problems.

For example:

• Wiring loom faults affecting signal transmission
• Transmission control issues triggering warning lights
• Communication problems between control modules

Correct diagnosis ensures the right component is repaired and prevents unnecessary replacement.


How Instrument Cluster Repair Works

All repairs at Remanufactured Parts Ltd are carried out on removed vehicle electronic components.

Customers remove the faulty instrument cluster and send the unit to us for testing and remanufacturing. Once repaired and fully tested, the cluster is returned ready to be refitted.

This process allows fleets to restore dashboard functionality without needing to bring the entire vehicle to the workshop.

Repair Instead of Replacement

Repairing instrument clusters through remanufacturing helps extend the life of existing components while reducing waste and controlling maintenance costs.

For fleets operating trucks, buses and specialist vehicles, instrument cluster repair can provide a reliable and cost effective alternative to replacing the entire dashboard unit.

If your dashboard display is showing faults or intermittent behaviour, early inspection and repair can often prevent more disruptive failures later.
