Flash or Pass
A few decades ago cars were just . . . well, cars. They had an
engine, transmission, a starter, a heater, maybe an air conditioner,
and all the usual accouterments that made them a car. Mechanics
toiled away at replacing engines, rebuilding master cylinders, and
fixing transmissions. Almost every component on the car was
reworked to a like new condition and some parts may even have
been rebuilt several times, before they were too worn out to go
around the horn one more time. Labor rates raised and fell with
the economy, while parts suppliers kept up the demand for
rebuild kits as a normal over-the-counter parts inventory.
Then somewhere along the way something changed.
The era of the microchip followed right along with the era of plastics. Things were built not to “rebuild”, but to toss. Thin plastic housings with hundreds and hundreds of micro circuits all wired into a microchip made up circuits that allowed the impossible to become the possible. Some tasks became obsolete, like the telephone switch board operator, even bank tellers nearly went extinct when the ATM machine was developed. The world would never be the same with the microchip in every facet of modern life.
Machining tools could now process and manufacturer automotive parts at such close tolerance that less material was needed per component. The prices for some of these components fell to less than or equivalent to the rebuild kits. Rebuilding an automotive component was soon a thing of past generations. The skills of the mechanic were now overshadowed by the microchip’s ability to manufacture a part better and cheaper than he could repair the old one.
Soon, all this “toss-when-worn-out” reached the microchip itself. Computer software started finding itself in the very same throwaway society. Maybe not in the sense that we actually threw it away, but a new set of instructions or an updated program may be needed and flashed into a replacement processor. This brings up a whole new problem for the mechanic. Now those skills he developed in rebuilding a master cylinder have next to nothing to do with reprogramming an anti-lock brake module, and if he wants to stay in the business of repairing today’s cars he’s going to need to know how to program, or at least understand the need for and/or the process, rather than knowing the old school way of rebuilding a master cylinder. So as a mechanic, you have to ask yourself, “Do I flash, or do I pass?” Passing on the flash may mean you might not have the type of work in the shop that you can handle anymore. Luckily, there is a way around that problem.
These days nearly every car on the road has more than one type of computer device in the car, and there’s a very good chance that at some point something will need a software update or re-flashed because a component has been changed or upgraded. In a way re-flashing, programming, coding, or the other various software issues there are in the modern car are somewhat of today’s version of rebuilding that master cylinder to a like new condition.
Cars these days are lasting longer, running longer, and have different types of break downs than models from those early days. That’s doesn’t mean changing brake pads or installing a reman transmission isn’t done on a daily basis, they most certainly are. It’s the other side of the repair business, the computer updating and re-flashing that’s an even bigger part of regular maintenance than ever before.
So, which type of repair shop are you? Are you the shop that will do the mechanical work, but leave those electronic issues to someone else? It’s something every shop owner, as well as technicians need to think about. Of course, the amount of investment and the continual training involved can be overwhelming. Fortunately, there is a way to do the mechanical stuff and be a proficient repair shop without breaking the bank, and still service your customers’ electrical and software needs. The mobile diagnostic technician is the answer.
Seriously, I never dreamed there would come a day I would be saying this, but the mobile tech is a viable source of revenue and a vital source of technical skills that a shop without those skills should utilize. Now, I’m not talking about those fly by night boys with a box of tools, I’m referring to the diagnostic scanner mobile tech who has the experience in dealing with all the websites, programming issues, and has the up to date information on how to perform such things as re-flashing, key programming, and reloading of new software.
What’s happening in the automotive electronic world reminds me of how things were when manufacturers switched from points and condensers to electronic ignition systems. A lot of guys refused to learn the new systems and soon found themselves only working on older models, which eventually faded away.
Somewhere along the way of the electronic ignition systems, parts swapping became the norm. Instead of testing or diagnosing a problem it was a lot easier to keep the various types of ignition modules in your tool box, and when a “no-start” came in it only took a few minutes to swap the ignition module with your test piece. It did save diagnostic time, and it did get results, but the microchip and new technology has struck back again. The old school ways of parts swapping vs. in depth diagnostic with scopes and scanners has just about run its course. Now, swapping components can lead to an even bigger problem than what the car originally came in for.
However, the general public is having a hard time comprehending the reason for these diagnostic costs. It used to be that they would bring the car to the shop, the mechanic would do some fiddle greasy job that involved rebuilding some part or swapping the old ignition module, and he didn’t charge a diagnostic fee. If a part was suspected as bad, it could usually be swapped out without any worries. That’s just not car repair anymore. Now swapping components with integrated modules can lead a disaster.
On the other hand, those techs who pick up the pieces after one of these parts changers finish slapping parts should be commended. The aftermath of installing a processor without knowing the eventual outcome can be a brutal blow to the pocketbook.
Radar systems, infrared and optical systems, cameras and proximity sensors aren’t the kind of components easily rebuilt, if at all. But, there’s a good chance you can reprogram most of it. Yes, we still have engines that need built and gears that need changed, but there seems to be a lot more in the mechanic field that involves electronics. To be today’s top mechanics and a repair shop that can get the job done, a lot more emphasis has to be put on that little microchip than on a rebuild kit. Flashing modules and loading computer software updates are just a part of the business now.
Programming ain’t for everyone, and some shops and techs can get by without ever dealing with it, but when needed, utilize the expertise that is available to you. Learn how to flash by attending a couple of classes or find someone that can do it for you. Help your customer help you increase your bottom line, don’t pass on the flash.
