Vehicle diagnostic testing | Highway Auto Rockhampton

Vehicle diagnostic testing has evolved out of need to quickly and accurately diagnose modern computerised cars which rely on fast data transfer to function.

Vehicle diagnostic testing is a simple way for Technicians to figure out what is wrong with your vehicle. We offer a free diagnostic test when you bring your car in for routine maintenance, and these tests can help detect a problem before it spirals into a major headache. Beware, its not all that simple so read on.

How Does Diagnostic Testing Work?.

When your grandpa took his car into the shop, he likely took it to a dealer that specialized in a certain brand or vehicle type. Back in the day, mechanics had to figure out what was wrong with the vehicle based on an inspection, the sounds the car was making, or what color liquid was dripping from the bottom. It took a skilled mechanic to correctly identify a complex problem.

Today, Technicians and Mechanics have it easier because a computer can help diagnose the problem, but they have to be more skilled at servicing a wider array of problems on a bigger selection of cars and still require extensive training and experience.

To figure out what’s wrong with your car, a Technician will look at your vehicle’s Electric Control Unit (ECU). The ECUs are present in all modern cars, and it makes it much easier to determine what’s wrong. When your ECU detects a problem, it turns on a light on your dashboard. Oftentimes this is the Check Engine light, but it can also turn on other lights, like your ABS or Oil lights. When you bring your car into the shop, a Technician can download the error report that caused the light to turn on in the first place. The Technician then compares the report to the manufacturer’s error log to determine the issue.

At first glance the above is substantively correct, however it is not that simple because historically many expensive electronic components have been replaced unnecessarily because accurate automotive diagnostics only works in that simple form so long as the Technician can recognise Ghost Fault Readings and allow for them in his/her final summation of the problem. Highway Auto Diagnostics Technicians have extensive skills in this area so your vehicle’s diagnosis will be accurate and correct.

ECU Health Check and Report.

Modern vehicles are controlled by many sophisticated on-board computers are more commonly known in the industry as Electronic Control Modules (ECMs) or Electronic Control Units (ECUs). In fact, some cars have over 20 different control units that are constantly reading, exchanging and manipulating data between themselves. When a module senses a problem with an electronic command, it will often override the issue by altering the parameters of the pre-programmed data without “advising” you through lights on the dash.

ECUs make these improvement processes automatically and in real time. In a closed-loop system, different sensors accumulate data from the network and send data to actuators that provide the interventions required to achieve the best outcome for the driving conditions and service item condition it has to deal with. The output of sensors tell the system what the car is doing and the contribution of new inputs back to these sensors from the ECU makes the critical amendments.

Some ECU tasks in your car they assist in the functioning of:

  • Traction Control

  • Park Assist

  • Supplemental Restraint Systems (Airbags)

  • Automatic Climate Control

  • Tyre Pressure Monitoring Systems

  • Cruise Control

  • The Anti-lock Brake System Control
