Operating a car in the 21st century can be expensive, especially if it’s out of warranty. Troubleshooting can be especially costly, especially if the repair center has resale experience to ensure you do repairs with them.
However, all this means that you can save on repairs. Vehicles out of warranty performing their own troubleshooting using a dedicated USB cable and diagnostic utility. You can then use this information to track down a problem with a specific component (perhaps a temperature sensor, perhaps the brakes) and arrange for necessary repairs.
Troubleshooting in the car
One of the biggest challenges for car owners in the 21st century is troubleshooting. Even 20 years ago, repairing a car meant finding the problem through a series of checks. Some of these checks may not be entirely reliable and may also require the removal of entire subsystems, but overall it was an easier process. The cars were mostly about mechanics, which meant no special computer knowledge was required.
Since about the mid-1990s, this has changed at almost every level of mass-produced vehicle manufacturing, and the rapid spread of computerization and the introduction of sensors and electronic monitoring of components and subsystems has meant that some parts may be blocked. replaced and how.
After all, how do you replace a part if you can’t diagnose the problem? Diagnostics these days takes place under the scrutiny of a repair team or expensive third-party manufacturers.
But this is optional.
What is OBD II?
Somewhere in your car there is an OBDII port, a SCART style connector that provides connection to the ECU (engine control unit) and through which diagnostic information (and monitoring data) can be obtained.
The spec for OBDII says the port should be no more than three feet away from the driver, so inspect the crank and handle, under ashtrays, under the dash, etc.
This means you can repeatedly diagnose problems and monitor your car’s performance! You can even combine it with Windows-based navigator installation plans, perhaps using an old laptop or netbook. .
