How to Scan Your Car for Diagnostic Trouble Codes Video
If you see a "check engine" or a "service engine soon" light in
your instrument cluster; your car has stored a diagnostic trouble code. This means
the computer system on your vehicle has detected a problem with the various systems
it controls. Your car has many different sensors that monitor the various vehicle
systems. If the trouble code light has been illuminated your vehicle enters into
"limp mode" this means it is running on a predetermined program that causes poor
mileage and increased emissions. An engine trouble code reader is an easy to use
tool. All 1996 and newer vehicles utilize a "D" style plug-in connector that connects
to the code reader. On most vehicles the connector is located at the driver's compartment.
Once the code reader is plugged in you can retrieve trouble codes the engine computer
has stored in its memory. These codes are the same codes the dealer and repair shops
use to replace sensors and clear codes. This video contains basic a testing procedure using an automotive
trouble code scanner as a code retrieval tool. Correct computer system function is essential for your car's engine
to operate properly. Many engine run-ability problems can be related to a weak or failing
sensor producing a diagnostic trouble code. Problems can range from hard cold
engine starting, low power and stalling
while driving. This video contains visual information designed to aid a trouble
codes retrieval test using a engine code scanner.
