A large number of vehicle problems can be checked for using diagnostics, from checking that your car’s components are running as they should to detecting where problems need to be addressed. From air temperature monitoring to RPM checking, confirming air bag and A/C systems are not faulty to picking up ECU systems cars have installed, you can get your car’s health checked by a reputable mechanic either using stand alone diagnostics equipment or they may use a portable scanner. Diagnostic scanners are attached to your car through an EOBD connection in the vehicle and readouts are generated, which you can print when computer based diagnostics are carried out. The error codes produced inform the mechanic of vehicle issues that exist and need fixing.

Consistent technological advances are always improving vehicles, and increasing numbers of functions are being managed by built in computers. Therefore diagnostics are required to find out whether there are problems. Many functions are handled by electronic control units, such as door control units and force feedback pedals for accelerators, airbag and seat control units. Vehicles also often have electronically controlled brakes, and in order to enable servicing of brakes to take place, the callipers will have to be released which can be done using diagnostic controls.

Further to undertaking repair work, adjustment to the electronic control unit might be needed, for example, after installing a replacement control unit. Additional adjustments can also be needed to stop error lamps displaying on the control panel of your car. Functions that can be affected are air bags, immobilisers and alarms. Whilst ‘check engine’ indicator lamps can be indicative of engine sensors or monitors being faulty, it doesn’t necessarily mean vehicle part replacements are needed. Engine management system reprogramming could provide the answer to your diagnostic issues.

When your dashboard has illuminated engine management bulbs indicating a problem with your vehicle, diagnostic scanners can be used by Longton Motor Services to find out what’s wrong. Engine fault lights won’t always be illuminated when cars have problems, but you can use diagnostics to check any ECUs, which will allow the cause of the problem to be detected, whether your engine makes a knocking sound, or power and performance is diminished. Clearing code errors is a service that can be done by a diagnostics specialist, as can clearing malfunction indicator lamps, by carrying out minor onboard computer adjustments negating the need to replace components, which makes fixing your car problem less costly.

From ignition timing checks to tracking air intake ensuring efficient operation of engines, monitoring electronic brakes to control unit checking for seats and sunroofs, a large number of car problems can be diagnosed using diagnostic equipment. Despite ‘check engine’ lamps not always being lit, there may still be something wrong with your vehicle, which is why a diagnostic assessment can address any worries and enable the vehicle problem to be solved.

Other diagnostic analysis includes looking at values that are measured and activators. Live vehicle stats information is shown from measured values on diagnostic program displays whenever diagnostic readers are utilised to carry out system monitoring of vehicles. Displayed details encompass voltage from the battery and engine RPM, feedback from sensors for oxygen intake and coolant temperatures. By using an activator test, the effectiveness of activators can be checked. Switching the fuel pump on and fuel cut off are controlled by activators, as are door locking and unlocking controls and wheel locking.
