Engine Diagnostic Check

When a warning light or fault code suddenly appears on your dashboard, this can be a very unsettling experience. Especially if it’s the light that looks like an engine!

As vehicles become more advanced (with hundreds of sensors around the vehicle reporting back to your vehicle’s Engine Control Unit or ECU), so trouble-shooting becomes much more complex (often with hundreds of potential error codes).

At National, we can help diagnose these fault codes by interrogating your vehicles ECU (Engine Control Unit) with our state-of-the-art Engine Diagnostics Tool.

 

How does a Diagnostic Check work?

Our ‘SensorPad 8’ diagnostics tool simply connects via Bluetooth to a small VCI device (Vehicle Communications Interface) which in turn plugs into your vehicle’s on-board diagnostics port (usually located on the underside of your dashboard)

The SensorPad 8 will read the ECU’s fault code and turn off any fault lights when the problem has been fixed.

The SensorPad 8 can also perform actuator tests to make sure that certain components are working and getting signals from the ECU; re-programme components to rectify faults; re-set service lights (following a service) and wind back brake callipers on vehicles with electronic handbrakes so that the rear brake components can be accessed.

Diagnostic Health Check

Not all vehicles display warning lights or fault codes when something goes wrong and an Engine Diagnostic Scan can give an early warning indictor of problems which may develop in the future.

At National, we offer an ‘Diagnostic Health Check’ for just £30, which scans all the modules on your vehicle and can highlight any faults. The scan includes;

  • ECM (Engine Control Module)
  • TCM (Transmission Control Module)
  • ABS (Anti-Lock Braking System)
  • BCM (Body Control Module)
  • IMM (Immobiliser)
  • TPMS (Tyre Pressure Monitoring System)
  • SAS (Steering Angle System)
  • Lighting and Comfort Control System
  • Emissions Levels

 

What does a Diagnostic Check include?

A full system health check (our equipment will identify all modules connected to your vehicle’s ECU and individually check for any stored or current faults)

We will identify if the fault is “Current” or “Stored/Historic” – any stored or historic faults will be cleared from your vehicle’s ECU memory. Any current faults will indicate that something is currently not as it should be and in most circumstances we should be able to advise what work may be required.

The Diagnostic Check does NOT include the cost of any repairs, replacement parts, re-coding, etc.

Where we are unable to offer a suitable repair (i.e. electrical system faults) we will provide you with the fault codes that should enable you to obtain repair quotations from a specialist.

Engine management lights may not extinguish if a fault identified is not rectified.
