Auto Electrics Rockhampton-Car ECU & Electrics Best at HAE


Rockhampton's best & longest-serving auto electricians. Car electrical fault finding & all auto-electrical repairs will solve your car's electric problems fast.

Auto Electricians plus Computer Technologists Best in Rockhampton with Car Computer Technology. HAE’s Skilled technologists for fast, accurate diagnosis of auto ECU systems – ABS, ECU, EFI, AWD, ADAS, and AHS with a Lifetime Quality Guarantee.

Your car’s computer system is CAN, the Controller Area Network. It consists of several smaller computers called Electronic Control Units. The ECUs control different areas of the vehicle, such as the transmission, the brake system, engine components like the spark, EFI petrol injection, and safety sensors.

The sensors in each computer can detect things like temperature, air pressure, steering angles, and engine exhaust emissions. The information from these sensors moves throughout the CAN network and is sent to the rest of the ECUs to communicate. You may not have realised that your car has computer systems “talk” to each other, but you would recognise the results of that communication. Here are a few examples of what CAN does:

  • Turns your “check engine” light on

  • Controls the fuel injector flow and spark timing

  • Operates automatic transmission, your engine, and emissions

  • Unlock your car doors or enable your security system

  • Deploy air bags when necessary

 

Car Computer Problems


Like any other part, a car’s computer can create issues. Electrical short circuits and voltage spikes to the power supply could damage or destroy it. The vehicle’s environment can also harm it. Unlike the computer in your home, your car’s computer is exposed to the elements.

Excessive heat and moisture can lead to component and sensor corrosion. The vibration and electrical surges from the battery or starter can also cause problems with the computer. A damaged computer can lead to a malfunctioning car. How will you know when the computer needs to be looked at?

  • The “Check Engine” Light. If the light toggles on and off randomly and there doesn’t seem to be any issue with the engine, it’s a good indication that the car computer is malfunctioning.

  • The Car Won’t Start. If your car is difficult to start, the problem may not be just the engine. It could be that the computer isn’t communicating with it.

  • Excessive Fuel Consumption. Can’t travel as far as you used to on a full tank? It could indicate an issue with the computer sensor, but only if you notice the fuel economy has dropped over a short period of time.

 
 

Best Way to Troubleshoot Car Computers


When your car computer has problems, take your vehicle to the Highway Auto Electrics Rockhampton diagnostic lab, where a Computer Technologist will run onboard diagnostic tests to troubleshoot and identify the issue.

You will be informed of the outcome, and the Technologist will prepare a report and an agreed price quote.

Highway Auto Electrics (HAE) is a family owned and operated business, not a franchise operation, so we are cheaper than dealers and the big franchised names. Established in 1966 we have trained more than 103 technicians and pioneered CAN Diagnostics. You could not be in a better place to have your car’s electronic problems solved, better and cheaper than the rest.

Embedded software in ECUs continues to increase in line count, complexity, and sophistication which requires the high level of technical expertise you will find at Highway Auto Electrics Rockhampton.

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, 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.
