Diagnostics in Llandeilor-Fan

Controlling vehicle systems with ECUs

Constant vehicle technology improvements are being made and increasing numbers of functions are being managed by built in computers. Diagnostics are needed when things go wrong for that reason. An ECU manages many functions, such as door control units and force feedback pedals for accelerators, sensor clusters and control units for airbags and seats.

Electronic controls often cover brake systems too, therefore to allow brakes to be serviced, releasing of the brake callipers will be required which a diagnostic reader can usually do. Professional Llandeilor-Fan garage mechanics are trained to run diagnostic tests via your vehicle's computer.

Faults with vehicles that Fiat diagnostics can locate

From testing the timing of vehicle ignitions to checking oxygen intake ensuring efficient operation of engines, checking that electronically operated brakes are responding to seat and door control unit testing, diagnostic apparatus can find out what is causing a number of vehicle problems. Despite 'check engine' lamps not always being lit, there may still be something wrong with your vehicle, for which reason asking a Llandeilor-Fan mechanic to do a diagnostic analysis can allay and concerns and give you the opportunity to solve the vehicle issue.

Reprogramming vehicle functions in Llandeilor-Fan

Following repairs to a car in Llandeilor-Fan, ECUs may need to be reconfigured, e.g.

Following replacement of a faulty control unit.

Adjustments to other features can also be required on occasion to stop error lamps displaying on the control panel of your Citroen.

Functions that can be affected are alarms, body control units and immobilisers.

Though error lights can indicate a fault with sensors or monitors, it's not always the case.

Adjusting the computer or engine management system may put an end to your car trouble.

Measured value testing and activator system analysis

Other diagnostic analysis includes looking at activators and measured values. Live vehicle stats information is shown from measured values on diagnostic program displays whenever diagnostic readers are utilised to undertake vehicle analysis in Llandeilor-Fan. Functionality shown covers battery voltage engine speed RPM, oxygen sensor information and coolant temperatures.

Activator performance is assessed using an activator test to ensure everything is working. Activator controls include cutting off the fuel pump, locking and unlocking doors and locking the wheel.

When your dashboard has illuminated engine management bulbs, indicating that something is wrong with how your car is running, diagnostic scanners can be used by Llandeilor-Fan garages to source the issue. Sometimes you will know something's wrong but no warning lights are lit, but you can use diagnostics to check any ECUs, which will facilitate fault detection, from pinging sounds when accelerating, or you've noticed a reduction in performance and power.

Error codes can be reset by a diagnostics specialist, as can persistently showing engine management lights, by tweaking or reconfiguring ECUs as opposed to replacing vehicle parts, which makes fixing your car problem less costly.
