Most modern vehicles are moving in the direction of allocating many functions of the vehicle to be controlled by computer. This allows for fantastic new safety measures like electrically assisted braking and traction measures to assist you take sharp corners when driving through the countryside. Because these features are a little on the futuristic side, they go through rigorous auto electrical diagnostics testing before being launched into the market. Once you are used to them, you will find that it can be quite an interesting experience driving without them.
More and more components are being controlled by your vehicle’s onboard computer system. This means that more sophisticated diagnostic tools are required to read the error codes of this computer and then perform the necessary work. This also means that your vehicle can act a little strange, for no visibly apparent reason.
Jumping gauges, slow acceleration, remote entry failure and many other car electrical system issues can be caused by anything from a disconnected wire to a blown fuse. Many other automotive shops can incorrectly diagnose the issue as the Electronic Control Unit (ECM). Replacing this device is more often than not an expensive and unnecessary process.
Onboard computers are extremely reliable, and it is very rare for an Electronic Control Module (ECM) to require replacement. This means it is almost certainly an issue with some other component of the vehicle. Whether it’s fuses, a bad wire, or a sensor issue, our auto electric repair technicians have seen all the issues before, and odds are we already know a fix for the problems at hand.
Because so many of your vehicle’s processes are controlled by computer, small computer calibrations can lead to larger issues like a mistune of your vehicle. Incorrect electronic fuel injection measurements can cause a failed emissions rating and cause your “check engine” light to turn on.
Ultimately, the only way to make sure that all your issues are taken care of is to bring your vehicle to a professional for an auto electrical diagnostics and repair. Otherwise you may find that the issues are never fully fixed, and your “fine” vehicle will spend more time in the shop than on the road.
