Tech Tip: When having your vehicle repaired at some repair shops, if they tell you "well "we think"this is the problem with your vehicle .ask them if it's a guess,or guaranteed fix.if it's a guess,make sure the're not guessing with your money,and they are not installing parts you don't need. At John's,wedont guess with your money! if it's not repaired right the first time,the second time you don't pay!
Auto Repair andthe Myth of the "Magic Machine".
"Can't you just connect my car to a Magic Computer that will tell you exactly what's wrong with it and how to fix it?
This is a common Myth in the Auto Repair Business.True, diagnostics have evolved by leaps and bounds ,but is not in the Star Trek age....yet!
Todays modern computer-controlled vehicles are truly in the digital age.there are as many as 8 computers controlling everything from the engine, transmission,ciimate control system,body control module, and etc.Tracking down a problem and determining the process needed to repair the vehicles are still done the old fashioned way.a technician has to gather data by using his senses to see,feel,hear and smell,then collect the vehicle's stored data,and determine the best course of action/repair that need to be done.The vehicles' on-board computers have the capability of recording the codes that cause a driveablity problem or service engine light to come on.these codes are used to determine what component or system that my be affected."the diagonstic scanner doesn't reveal the cause of the problem,it just tells the technician where to begin looking ,and most of the time other test may be needed.
To properly diagnose the problem or rather the cause of a check engine light, you need to take your vehicle to a trained technician for a professional diagnosis. Not to the local discount parts store where you will only find parts counter people and not a real auto technician, the truth is they are there to sell parts, not to fix cars and most people end up at the repair shop anyway
with the same car trouble that they started with at the parts store, just with a lot less money.code readers are not scan tools.
the information gathered from a scan tool is just a clue for the"Automotive Detective":
The real answer to the problem doesn't come magically out of a machine ,but rationally out of the technicians head,"THE REAL DIGANOSTIC TOOL" To see how the check engine light works,click "Here"
We Specialize in Engine Diagnostics Service,Import and Domestic.
We do our own Computer Re-flashing and programming .The practice of updating software in these modules is more commonly known as "flash reprogramming". At new car dealerships, flash reprogramming is a relatively straightforward process because service technicians are connected to the automaker and have the expensive, specialized tools dedicated to reprogramming. The independent repair shops have faced a more difficult challenge because most shops typically service more than one make of automobiles. This increases the complexity, cost, and training required to operate dozens of different factory service tools
For years shops like mine and others have depended on Dealers for re-flashing whenever we needed to replace or update a PCM,Body Control Modules,Air Bag Modules,Transmission Modules,instrument Clusters and Etc..and to be honest, it was a pain in the ....... .it seems like we are running into it more often than ever with the new techknowledgey. now with the new computer and software we just purchased,we can do it for ourselves,"and for other shops".no more towing vehicles to a dealer and waiting for days.we will be able to do most makes and models. at John's ,we try to be your one-stop-shop !
The days of diagnosing and repairing automobiles without a laptop and a passthru device are fading. Newer vehicles have large number of onboard computers, each dedicated to performing specific tasks.
Each onboard computer is programmed at the factory with software enabling it to perform certain tasks. Inside the ECM is software containing hundreds or even thousands of parameters to control spark, fuel, cruising, emissions, idle, economy, drivability, and performance. Similarly, a TCM will have software to control how the transmission and torque converter function. Sometimes, after the vehicle is shipped from the automaker, updates are released to improve emissions, fuel economy, drivability, performance, or specific bugs in the original software that have caused warranty issues. Updating this software can be a proactive fix because often it will resolve problems that a customer hasn’t reported or noticed yet…
