The modern vehicle is reliant on a number of electrical management systems.

Management fault lights display for a number of reasons. Sometimes it can be just a simple

fault that can be cleared; however, more serious faults can develop, including vehicle safety

system. Here a list below of some common advanced issues we can address.

AIRBAG SYSTEM / SRS (SAFETY RESTRAINT SYSTEM)

Trace faults and Rectify on Airbag Systems

ENGINE MANAGEMENT

The engine mangement warning light indicates a fault with either the emmisions or a mechanical or electrical

failure of the engine components

We can read fault codes, program the engine ECU, program new injectors and diesel pumps, reflash the

engine ECU to the latest calibration files and carry out basic settings on other components including EGRs,

throttle bodies and many more

Often an engine warning light will come on if a vehicle has not been regularly serviced

DIESEL ENGINE MANAGEMENT

The glow plug warning indicator can remain on when there is a fault on a diesel engine

These faults can range from faulty glow plugs, injectors, diesel pump, low fuel rail pressure just to mention a

few

The glow plug warning lamp can also illuminate when there is a problem registered with the DPF (Diesel

Particulate Filter)

This warning light should illuminate and then extinguish when the engine is started if operating correctly

We are able to diagnose faults, program diesel pumps, injectors EGRs, engine ECUs and more

IMMOBILISIER SYSTEM / KEYS

All modern vehicles have immobiliser systems which are integrated into various components of the vehicle

These systems are particular to each manufacturer and model

Often changing a component it is necessary to configure the keys and the immobiliser in order for the vehicle to

run again

With certain manufacturers a security code is required and available from the manufacturer (Peugeot, Citroen &

Vauxhall)

Other systems require us to connect to the manufacturer’s server in order to carry out immobiliser / key

programming

ABS SYSTEMS

The Anti-lock brake system (ABS) has a sensor that measures the wheel speed on each road wheel. When the

engine is started the ABS system carries out a self test and if no faults are registered the warning lamp will

extinguish

We are able to diagnose faults and program the ABS pump

TRACTION CONTROL & STEERING ANGLE SENSOR

Working as part of the ABS pump the traction control system independently brakes a road wheel which is

turning faster than the calculated speed of the other wheels with exception to the front wheels when turning

In order for this calculation to be carried out correctly on the front wheels an angle sensor that measures the

rate of turn known as the steering angle sensor is required. This steering angle sensor needs to be calibrated

to a zero point with both front wheels in the straight ahead position. The steering angle sensor calibration is

necessary when the steering column, steering rack or other suspension components have been removed or

replaced.

In some vehicles this warning lamp will illuminate if there is a failure of the brake pressure sensor which is

integral to the ABS pump

TYRE PRESSURE MONITORING SYSTEM (TPMS)

Some tyre pressure systems work using a pressure sensitive valve, others work on a calculated pressure

relevant to tyre rotation rate i.e. a flat tyre rotates at a different rate to an inflated tyre. This rotation calculation

is done by the ABS module

If replacing a valve , the numbers on the new valve needs to be programmed into the tyre pressure system

using the relevant diagnostic tool

It is important to make a note of the numbers on the new valves before the tyres are fitted

We can diagnose ,reset and configure these tyre pressure systems

XENNON / HEADLAMPS

Xenon Headlamps are high voltage lighting systems, these headlamps have a control module that uses inputs

from the ride height sensors to level these powerful lights to a pre-set level

A Xenon headlamp warning light and/or malfunction will soon be an MOT failure

DIESEL PARTICULAR FILTER

Modern Diesel vehicles are fitted with Diesel Particulate Filters (DPF) . This system is a filter that traps harmful

soot particles from the engine emissions. The system carries out a regeneration (a burn cycle) using a special

oil within the system every 600 miles provided the vehicle is driven at at constant speed and constant rpm

The problem with DPF’s is that if the vehicle is driven small distances or in start stop conditions the filter fills up

and never gets the opportunity to regenerate .These systems are costly to replace and the special oil that it

requires is rather expensive too. To keep your DPF working properly a regular motorway run for at least 20

minutes at a good constant speed is what is required. A DPF can also get blocked if a sensor fails to operate

correctly thus prohibiting the conditions necessary for a regeneration to occur

We can carry out a forced regeneration and diagnose faulty systems

A forced regeneration on a full DPF can cause a fire . We will not force a regeneration if the DPF is full

ELECTRONIC PARKING BRAKE (HANDBRAKE)

Modern vehicles use an ECU to control the parking brake. These systems electronically control the rear

callipers to actuate the parking brake . When changing rear brake pads it is important to electronically open

the brake calliper to replace the brake pads then close the system again

We can program parking brake modules and use our equipment to open an close these callipers

ELECTRONIC POWER CONTROL

An EPC warning can relate to any electrical system malfunction , often related to brake lights or other electrical

failure

We can diagnose these faults and address the issue

AUTO STOP START

As the green movement grows in popularity and the EU directives relating to vehicle emissions get stricter the

stop start function has evolved. These systems will automatically turn the engine off if the vehicle is left idling

for a predetermined amount of time

In order for this system to function certain parameters need to be met e.g ambient temperature and engine /

coolant temperature etc.

We can diagnose and configure these systems

NEW BATTERY PROGRAMMING

Vehicles today have a system that manages the charge rate of the alternator. This allows the battery to be

charged more as it begins to age to give it a longer life and to maximise the charge to sustain the draw from all

the electronic consumers

When a new battery is fitted the system needs to programmed to allow a charge rate that is suitable for the

new battery . Failure to carry out this function can result in over charging the new battery

We can carry out battery programming

SERVICE REMINDER

We can reset the service reminder on most vehicles including Long Life intervals

Often a service reminder cannot be reset as it has gone so far passed the recommended service mileage we

have equipment that can reset these service reminders

ELECTRONIC POWER STEERING

Most vehicles today have electronic power steering systems, these can shut down in the event of an accident

or can be damaged as a result of the initial impact

These systems need to be configured and usually will not work until the configuration is carried out

We can diagnose , fault find and configure these modules
