Diagnostics in
Reading activator outputs and measured value information
Other diagnostic analysis includes looking at activators and measured values.
Live vehicle stats information is shown from measured values on diagnostic equipment program displays when readers are used to analyse car systems in .
Features displayed include speed of the engine and voltage of the battery, coolant temperature and information from oxygen sensors.
By using an activator test, the effectiveness of activators can be checked.
Fuel pump controls, both cutting off supplies and starting up the pump are activator controlled, as are door locking and unlocking controls and wheel locking.
Car features controlled by ECUs
Technology for cars is always improving with on board computers controlling more and more features.
When things go wrong, diagnostics are therefore required.
ECUs control many functions, such as adaptive cruise control, door control units, sensor clusters and airbag control units.
Brakes are also frequently controlled and in order to enable servicing of brakes to take place, calliper releasing is necessary which a diagnostic reader can usually do.
Garages in will have the necessary knowledge to run diagnostic tests via your vehicle's computer.
What can you find out by running vehicle diagnostics in ?
Using diagnostics can check if your vehicle has any problems, from ensuring that vehicle components are working properly and efficiently to detecting where problems need to be addressed. From keeping an eye on temperatures of air intake to monitoring engine speed and RPM, making sure air bag and air conditioning systems are working to picking up any onboard computer systems in a car, a reputable mechanic can assess your car using diagnostic equipment that stands alone or with a diagnostic scanner that is hand held.
Diagnostic scanners are attached to your car via the EOBD port and readouts displayed and able to be printed out if using PC or computer based diagnostics, let the mechanic know what issues are there and need repairing.
specialists at vehicle diagnostics assist with
When you have engine management lights showing, giving indication that a problem exists with your car, garage specialists can run diagnostic tests to find the root of the problem. Occasionally, error lights don't show, but you can use diagnostics to check any ECUs, which will allow the cause of the problem to be detected, from pinging or knocking sounds coming from the engine, or you're finding power is being lost.
Error codes can be reset by a diagnostics specialist, who can also check malfunction indicator lamp statuses, by tweaking or reconfiguring ECUs rather than carrying out part replacements, which makes it that repairing your vehicle doesn't have to be as expensive.
Adaptation of vehicle features in
Once car repairs have been completed in , your car's ECU might need to be reprogrammed, e.g. Following replacement of a faulty control unit. Other features may also need adjustment to extinguish error codes lit up on the vehicle instrument panel.
The functions that this can affect include alarms, body control units and immobilisers. Whilst 'check engine' indicator lamps can indicate a fault with sensors or monitors, it doesn't necessarily mean part replacements are needed. Recalibrating the engine management system may put an end to your car trouble.
Diagnostic problems with Lotuss that assessments can identify
From testing the timing of vehicle ignitions to oxygen sensor checking to make sure engines run efficiently, ensuring electronic brake systems are working effectively to seat and door control unit testing, a wide range of issues can be found with diagnostics.
Despite no engine warning lights being illuminated, your car could still have an issue, so getting a mechanic to run a diagnostic assessment can put your mind at rest or allow you to resolve the problem.
