    Connect & Detect Overview

    Do you have a warning light on your dash, don’t know what it means? Is your car running a bit rough lately?

    These days it’s not as easy as popping open the bonnet and finding the problem. Vehicles are now controlled by sophisticated engine management systems which are similar to your computer at home.

    Your engines computer is known as an “ECU” and reads and stores the fault codes from your vehicle. Up until now this information has only been accessible by mechanics with the specialised tool, however partnered with industry leader Bosch, Supercheap Auto now offer this service at selected stores.

    Frequently Asked Questions

    YES! Using the service is easy – our specially trained team members will connect the diagnostic tool directly to your vehicles OBD2 port. This relays any information back on any stored error codes. You will be provided with a hard copy report of the results including identified fault codes and descriptions.

    NO! The test is completely safe and will not have any affect on the warranty.

    To connect to your vehicles computer your car will need to have an On Board Diagnostics Port (OBD2). These were fitted to most vehicles after 1996, therefore dependent on the year of manufacturing there is a good chance your car will be eligible.

    Your vehicle may enter ‘limp mode’ with limited drivability. Continuing to drive with the problem unrepaired could damage components of the vehicle, or could result in poor fuel consumption. It is advisable to visit us for a check as soon as you notice the warning light.

    YES! The tool can even reset the service interval warning lights if you’ve completed a DIY service. Some modern vehicles need a diagnostic tool to activate the wiper blade change position, as well as needing the tool to inform the vehicles’ ECU that a new battery has been installed. It can also help diagnose any problems which may be causing the car to run poorly, or suffer from poor fuel consumption.

    Although a check engine light can come back with any number of engine faults, the most common problem tends to be the Oxygen Sensor. This sensor can have a drastic effect on your cars ability to run smoothly, and can affect your fuel economy potentially by up to 40%. Learn more about Oxygen Sensors below.

    Oxygen sensors are a critical component of your engines operating system. Fitted to most engines since 1980 and every new car off the factory floor today, they can be overlooked at general service intervals with detrimental results. The oxygen sensor is a physical sensor mounted inside the exhaust where it is able to obtain a reading as part of the emission control system. This information is then relayed back to the engine management computer where it can determine if it’s running as efficiently as possible while taking emissions control into consideration. Every engine has a perfect ratio of fuel and air delivery which allows it to run as well as possible. If your engine isn’t running within this ratio it may be running either too rich or too lean.

    Rich - Rich is when there is less air being delivered then your engines perfect ratio. This means that a rich engine will have more fuel left over after combustion. This unused fuel also creates a greater level of pollution

    Lean - Contrary to rich, if there is more air then required being allowed into the engine, this excess oxygen will throw out the perfect ratio and your car will suffer. If your motor is running lean, not only will you experience poor performance, you may cause damage to your engine.

    How do I know if my Oxygen sensor is faulty?

    Here are some of the more common effects a faulty unit may have on your car:

    Sudden drop in fuel economy - If the oxygen sensor fails, the engine is unable to obtain a clear understanding of how much fuel it needs and as a result, additional fuel can be pumped through into your motor.

    Drastic change in engine performance - The oxygen sensor plays such a critical part in your cars fuel delivery system, a faulty sensor will be unable to correctly determine the volume of fuel required. This will result directly in lack of engine performance that will be quite noticeable on your daily drive.

    Harsh idling - Idling will also be affected due to changes in fuel delivery. The effects can alter from significantly rougher idling, to sporadic fluctuations in idling behaviour. This should be quite noticeable and therefore one of the easier methods of detection.

    Strong smell of fuel - If the engine is running rich, there will be more fuel being pumped into the engine and a distinctive fuel smell may be present from either the exterior or interior of your car.

    No, in most cases the store will be able to assist you straight away. However, during busy times such as weekends, a short wait may be necessary.

    To scan your vehicle will take approximately 15-20 minutes for Level 1 and 20-30 minutes for Level 2. It may take longer where the vehicle
    has numerous fault codes present.

    Knowing first hand what issues your vehicle may be experiencing can give you the confidence to make informed decisions about how to repair or service your vehicle.

    Fix It Yourself – If you’re the DIY kind of person we can help you order in any required replacement parts.

    Take To Your Mechanic – If you prefer to have the car fixed professionally you can take the report directly to your mechanic. You could potentially save on costs as you may not need the mechanic to perform the diagnostic scan.

    "The Diagnostics service was a good starting point by being able to talk to staff directly, and being able to look at the screen on the Bosch tool." Ian

    "There was an ABS light on the dash. The diagnosis was correct. It was also very well priced compared to mechanics…" Shane

    "There was an air bag light on the dash. There were a few fault codes, cleared as much as he could and told me what was wrong. The information was extremely useful." John
