Diagnostics in Colchester
Controlling vehicle systems with ECUs
Technology for cars is always improving with on board computers controlling more and more features. As a result, diagnostics are becoming more and more important when faults occur. Many functions are handled by electronic control units, such as adaptive cruise control, door control units, sensor clusters and control units for airbags and seats.
Brakes are also frequently controlled therefore to allow brakes to be serviced, releasing of the brake callipers will be required which can be done using diagnostic controls. Reputable Colchester garages have the expertise to run diagnostic tests via your vehicle's computer.
What can you find out by running vehicle diagnostics in Colchester?
A wide range of vehicle issues can be checked for using diagnostics, from ensuring vehicle systems are running efficiently to locating issues that need addressing. From air temperature monitoring to RPM checking, making sure air bag and air conditioning systems are working to picking up ECU systems cars have installed, a knowledgeable Colchester mechanic can check your car's health either using stand alone diagnostics equipment or with a portable diagnostic reader. Scanning devices are connected to your car through the vehicle's EOBD connector and readings generated, which you can print when diagnostics via a PC are completed, tell the mechanic what problems exist and require repair.
Colchester vehicle diagnostics specialists solve car faults
If your vehicle is displaying engine fault lights, showing that your vehicle is not running as it should, specialist Colchester garages can use diagnostic readers to locate the vehicle problem. Warning lamps don't always show, but a diagnostic program can be used to check onboard computer functionality and can detect the cause of a problem, from pinging or knocking sounds coming from the engine, or you're finding power is being lost. Resetting of error codes can be carried out by a specialist in diagnostics, as well as addressing warnings from engine management lamps, which they can frequently solve with small on board computer amendments rather than needing to replace components, so it can be more cost effective than you'd expect to solve your car problem.
Engine management function resetting in Colchester
Following repairs to a car in Colchester, resetting functions in ECUs may be necessary, for example, after installing a replacement control unit. Adjustments to other features can also be required on occasion to clear warning lamps showing on the dashboard. These include alarms, body control units and immobilisers.
Although 'check engine' lights can show that monitors or sensors have developed a fault, there can be exceptions. Engine management system reprogramming can sometimes extinguish the light and solve the problem.
Reading activator outputs and measured value information
Other diagnostic analysis includes looking at activators and measured values. Information from measured value outputs is shown on display screens when readers are used to undertake vehicle analysis in Colchester.
Features displayed include speed of the engine and voltage of the battery, oxygen sensor feedback and temperature information about coolant. 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 locking of both the steering wheel and the vehicle doors.
