New Car Care: The Dos and Don’ts of Modern DIY Repairs

Car repair

New car care is occasionally more complicated than simply breaking out a socket set and replacing a worn out part or two. Increasingly, vehicles require that their electric components be linked together in order to function properly, and this can mean that plug-and-play is a thing of the past: calibration and programming of specific control modules and other parts are now a crucial part of getting a repair done.

This type of work often requires specialized tools and equipment that financially are out of reach of the average home mechanic. Don’t worry: There are still some jobs you can do at home without investing in pricey programming gear. Let’s take a quick look at the dos and don’ts of modern DIY repairs.

Brakes, Oil Changes, Wheels and Tires

TireIf you’ve always changed your own brake pads and rotors, drained and replaced your own oil and filters and swapped out your summer wheels for winter wheels with the changing of the seasons, you can relax. None of that work is in danger of requiring a programming degree to accomplish. At the very worst, you might be asked to reset the oil change interval monitor on a modern car, which can be done easily using the infotainment or driver information controls.

ABS Pump and Engine Control Module

Once you start to get into components that actively communicate with other parts of your car, things can become more complicated. For example, an ABS pump is straightforward to replace, but you might not be able to access its bleed functionality after it’s installed to make sure you get all the air out of the unit. Likewise, an engine control module is often a blank slate until it’s been programmed to properly interact with all the other electronics in your vehicle. You may also find this to be true of window control switches, seat controls and remote door lock activators, which at the very least might require a reset using a factory tool before they will function properly.

Borderline Tech May Work

In the grey zone between these two new car care worlds are features that sometimes work after you perform certain steps, or which might still need professional intervention. These can include infotainment system screens and modules, which may have anti-theft steps you need to go through before they’ll power on, and tire pressure monitoring systems, which sometimes ask you to perform a procedure that adds or removes air from each tire, in sequence, in order to calibrate.
