showing 3 images of various diagnostic equipment

L V V Services now offers a fully mobile vehicle diagnostic service which can diagnose and switch off abs lights, airbag / SRS lights; engine management lights, service lights etc.

We are based in Bridgend, South Wales and cover an area from Newport to Swansea along the M4 corridor and the surrounding area.

Why do we need Car Diagnostics Services?
Typical EOBD Port
Over the last few years cars have become much more complex, in an effort to cut emissions and to make cars more fuel efficient.

One of the consequences of this is a much heavier reliance on state of the art electronic control systems throughout the modern motor vehicle some cars have in excess of 10 electronic control units.

Year on year the electronics become more complicated and although modern motor vehicles are quite reliable, modern electrical problems can be quite complex and it is definitely no longer an area where the individual should try his or her DIY skills

The consequences of getting it wrong could be expensive at least and with airbag systems in mind, even lethal if very unlucky!

That is where we come in; using specialist equipment we can diagnose 90% of problems usually within a few minutes

Your vehicle has a diagnostic port usually under the dash or around the centre console area this is called an EOBD port.

Car Diagnostics explained

EOBD stands for European On Board Diagnostics.

At the EOBD port we can plug in specialist electronic scan tools and take information or live data from the various control units that are in the vehicle.

Typical EOBD Scan Tool

In the case of a warning light on your instrument panel we would interrogate that particular system and reset any fault codes and advise of any problems.

What cars do we do?

We cover a good range of European and Japanese cars and also can diagnose a small number of American cars.

We cover around 90% of vehicles, even more on the engine management side as the EOBD protocol is an industry standard in Europe.

The EOBD protocol covers engine management systems in an attempt to cut down on emissions and to make vehicles as fuel efficient as possible.

This varies from one vehicle to another but typically we cover the following systems;

Engine Management Systems

Airbag / SRS Systems

The CANbus system

Later vehicles have now got a CANbus system which is a complex digital system that significantly reduces wiring requirements. Introduced by Bosch the CANbus system is now an international standard (ISO 11898)

A single pair of cables is all that is required to carry streams of data to control and operate many different functions of a vehicle at the same time. We now have a Canbus adaptor for 2 of our scan tools and programmes are being developed to diagnose these systems.

The CANbus or Control Area Network bus system

Is a high-integrity serial data communications bus for real-time applications

Operates at data rates of up to 1 Megabits per second

Has excellent error detection and confinement capabilities

Was originally developed by Bosch for use in cars

Is now being used in many other industrial automation and control applications

Is an international standard: ISO 11898
