Accurate Diagnosis of Computerised Car Faults.

The above picture shows some of the electrical and electronic complexity hidden away under your dashboard and instrument panel. This wiring is a part of a controller area network (CANbus) which allows microcontrollers and devices to communicate with each other whilst connecting any number of computers (ECUs) together.

Car computers are software code intense with some having 10 million lines of code, while a Boeing 787 Dreamliner will have 6.5 million lines of code. With that in perspective you will appreciate that diagnosing faults in a computerised car is a serious business requiring high skill levels and much experience.

These computers are fed data from around 20 sensors at various parts of the vehicle, the greater levels of vehicle luxury the more sensors you will have. Should one of these sensors fail then a warning light and sometimes a buzzer will activate, that’s when you need to come and see us for an accurate diagnosis of the fault.

Is It The Starter Motor or The Battery At Fault?

Car starter motor Your starter motor is an electrical device used to start the vehicle’s engine. The starter motor is a part of a starting system consisting of the starter, a starter solenoid and the battery.

As the ignition switch is turned, it triggers an electrical impulse to the starter solenoid. This, in turn, connects the battery to the starter motor that cranks the engine until it starts. Once the engine fires into life, the starter motor clicks off and disengages the starter ring gear.

Essentially, the starter motor provides 'the crank' to start your vehicle’s engine. It relies on the battery to provide the power to do this. So, if your battery is compromised, your starter cannot start your motor. However, if your starter is at fault you will often hear a 'click sound' as it attempts to perform its function, letting you know the starter motor has a problem

Starter motor repair is just a part of what we do, so if you have doubts about your vehicle's starter motor or electrical system, bring it into Highway Auto Electrics for an accurate diagnosis. Contact Us, Find Us, See Our Map, Get a Quote, Make a Booking

ABS brake controller

Car ABS brake central electronic controller Your vehicle's braking system is now a mix of electronics, electrics and hydraulics and of course the brake hoses and pipes that connect the lot together.

This equipment is necessary to achieve anti-lock braking where the wheel or wheels do not lock up under severe braking and or poor road surface.

The key to long trouble free life of this part of your brake system is to change out the brake fluid no later than 24 months. See our page on brake fluid.

Car Brake Computer Control ABS

ABS electronic controller circuit board Vehicle anti-lock brakes are a safety measure designed to assist you in maintaining directional control under the most severe braking conditions.

The brains driving this is the brake Electronic Control Unit (ECU) or brake computer. It processes the data from the wheel speed sensors and allows maximum hydraulic pressure to the wheels with best traction

As soon as a wheel breaks traction its speed increases so the computer restricts braking force to the wheel travelling at greater speed

Driving lights

Car driving lights and LED light bar See in the dark, turn night into day when you have the latest in night driving assistance. I'm talking about the latest LED driving lights and LED light bar, great for most vehicles.

If you have a vehicle not amenable to light bars and driving lights then we may be able to ramp up the power of your standard headlights. Not as good as LED driving lights but a great compromise that will help you see in the dark a little better.

Trailer Plug

Caravan trailer plug Your trailer plug as we call it is the electrical connection from your tow vehicle to your caravan. High load circuits that charge your caravan batteries and run your fridge while on the road need to come via a direct route from the vehicle power supply, be of suitable gauge to carry the required current and also have an interrupt device so as not to have the caravan flatten the vehicle batteries.

This little device can be a bundle of trouble if it’s not done by the book and you will need a skilled auto electrician to get this right and ensure your time on the road at all those free camp spots is happy and hassle free. Ring me on (07) 4926 1303.
