Electrical Faults

Vehicles are brought to us every day of the week with immobiliser problems and our experts have many years’ experience diagnosing the problem and fixing it in the most cost effective way.

Our specialists have many years’ experience diagnosing problems and overcoming the issues that have caused them. The type of issues we can diagnose and fix range from airbag, ABS, alarm and immobiliser issues, burned out wires and looms and many more.

Immobiliser Problems

Immobiliser problems are caused by a range of issues including key fobs which have lost their coding or with lost transducer chips, damaged or corroded wiring, faulty ECUs, CAN bus errors, faulty sensors and actuators, corrupted body ECUs, faulty BSI Units and damaged receiver rings.

Common Problems:

  • Central Locking not working

  • Alarm not Working

  • Car Won’t start – Immobiliser Light On

  • Car Won’t Start – Immobiliser Light Flashing

  • Car Won’t Start – Immobiliser Light Off, Car Starts Then Stops

 

ABS or Traction Control

If you’re ABS or Traction Control light does not go off within a few moments of driving you should always get the car to a specialist as soon as possible to have the problem diagnosed and fixed.

Common ABS problems are caused by faulty batteries, failed wiring or connectors, broken brake light switches and broken brake light bulbs.

As well as the danger that this poses for you, your passengers and other road users and pedestrians, your insurance will be invalid in this light is on at the time of an accident.

 

Engine Management Problems

We are experts in correctly diagnosing and fixing engine management problems.

Our diagnostic equipment allows us to pinpoint faults, even when main dealers have failed to do it. A number of main dealers in this area bring any engine management problems to us without trying to find and fix the problem themselves as it is more cost-effective for them to pay us for a correct diagnosis.

Airbag & SRS Problems

Most airbag and SRS faults are caused by bad connections and damaged wires. These types of faults can be notoriously difficult to diagnose without access to the correct specialist equipment which we have at Halls. This equipment helps us to quickly identify the area of the car that is causing a problem.

One of the most common problems is caused by adjusting the seats in a car. The wiring for airbags and SRS systems is generally thin and stiffens with age. When seats are adjusted it is common for the wires to break or for connectors to be pulled apart.

We have a lot experience with the common faults which enables us to produce significant savings for our customers.

Warning: Your insurance is unlikely to be valid if an airbag warning light is showing, so if you are involved in an accident you will not receive a pay out from your insurers.

Airbags contain sensitive and volatile explosives. Please do not attempt to work on or even disconnect any wires or connectors related to the airbag SRS system. Disconnecting a connector can result in activation and personal injury as well as damage to the seats, dashboard or other parts of the vehicle. Disconnecting the battery is not enough to avoid these dangers.

  

Body Control Systems

The majority of cars manufactured on the roads today have one or more Body Control modules which perform all sorts of functions, such as control the lighting components on the your vehicle.

Gone are the days when you push a switch that completes an electrical circuit to open a window. These days it is more likely that pushing a switch sends a signal through your car’s Can Bus Network to the Body Control ECU which then sends a signal to the window control motor which then opens the window.

The reason for this is that it allows such things as automatic window closure when you lock or alarm the car.

The problem is that while all this extra functionality may seem like a good idea when everything is new, but the increase of extra control components within a vehicle environment also greatly increases the chances of errors and faults to occur. But with the aid of dealer level equipment these faults can be remedied quickly and cost effectively.

 

Emissions

When there is a problem with your vehicle which affects emissions, it will automatically disable certain features to prevent any major problems, putting the vehicle into “limp mode.”

You will notice a loss of power when your vehicle is in limp mode. Our expertise enables us to determine which component is at fault, or if there is a wiring issue, and fix the emissions problem, saving you the time and money involved in replacing parts and systems which are not actually broken.
