Mobile Computerised Vehicle Diagnostics using professional test equipment and trained engineer.
Drivers and fleet operators require the best performance from their vehicle for comfort ,reliability and fuel economy.
Problems with the vehicle engine management, fuel & ignition systems may cause
MoT test exhaust emissions check failure due to excessive CO (Carbon Monoxide) or HC (Hydrocarbon) content in exhaust gas and damage to the environment
Vehicle operating conditions and driving cycle will have a huge impact on the type and frequency of servicing needed.
A vehicle operating on frequent short journeys may not reach normal operating temperature before it is stopped and may also suffer from battery charging system problems.
A build up of carbon and sludge deposits in the intake manifold can cause blockages and restrictions leading to malfunction of items such as idle speed control motor ,throttle flap,and exhaust gas recirculation (EGR) valve etc.
Engine control software may be remapped for better performance.
Performance upgrades are available which allow specific changes to the original software to meet individual driving requirements.
Manufacturers develop extended service intervals to reduce fleet operating costs.
Many vehicles are equiped with onboard service indicator lights to prompt the operator when a service or inspection is due. The service warning alert may based on time, mileage, or engine running hours frequency calculation.
Service Light Reset may require a specific procedure ar use of diagnostic equipment.
Vehicle computerised engine management allows better fuel consumption and reduced maintenance through electronic control of ignition timing, fuel mixture, and idle speed.
Inputs from sensors measure driver demand (throttle position), engine temperature (coolant temp), engine load (manifold absolute pressure), mass air flow and air temperature, exhaust gas emissions (Lambda), vehicle speed ,etc.
Input signals are transmitted along wires to a central computer, (ecu) where the received signals are processed and compared to programmed values stored as a memory map, then output values calculated, signals sent along wires to output actuators such as fuel injectors, control pressure regulator , cooling fan, idle speed control ,etc, to maintain performance factors such as smooth engine running, fuel economy, and low exhaust emissions.
Various factors can affect the efficient running of your vehicle engine :
Manufacturers test extensively whilst developing new vehicle models however unforeseen problems may only show following in service vehicle wear and tear.
Faults affecting exhaust emissions or driveability can sometimes only be corrected be updating the control unit software
The type of microcontroller chip inside the control module will determine the method required to update software. In some cases this may require replacement of the program microchip. Many vehicle software updates may be 'flash' programmed via the vehicle diagnostic connector using a pass-thru (SAE J2534) programming technique.
A manufacturer may release a Technical Service Bulletin (TSB) if specific recurring faults affect a particular model.
Updated calibration software is downloaded from the vehicle manufacturers website and transferred to the vehicle computer using the pass-thru interface

Computerised vehicle diagnostics is a means of using the ability of the vehicle computer control system to monitor the condition of vehicle components.
Unsure if you should drive the vehicle with a dash warning light on - We provide a breakdown callout mobile service that travels to you.
Intermittent faults which occur during driving may be logged as an error fault code which causes the dashboard warning light to illuminate.
Random disconnecting of electrical connectors in the engine bay may also cause fault codes to be logged.
Most modern vehicles require diagnostic equipment with dedicated software to interrogate the relevant control module for stored fault codes.
Automotive system electrical diagnostics involves an interrogation scan of the vehicle computer for stored fault codes using suitable diagnostic equipment such as a scan tool fault code reader.
Some older vehicles (usually Japanese) have a self diagnosis function allowing the the fault code to be read by counting the flashes of the check engine light and looking up the value in a reference table.
Following testing, a faulty wiring circuit may be repaired or component cleaned or replaced.
Our vehicle diagnostic equipment is capable of
Automotive diagnostics involves more than just plugging in a scan tool to read fault codes.
Diagnostic error codes provide a clue as to what the control system recognises as a fault but remember it is an electro mechanical system which is under repair.
Motor trade industry experience combined with investment and continuing professional development of staff through a system manufacturer training courses aids vehicle system diagnosis & repair.
