How safe is this code search?

http://www.allpar.com/fix/80s-codes.html Is this the same thing the auto shops do when getting a diagnosis code?? Thanks

For thoses models yes. But now notice that is not OBD2 Codes. 96 up

For ODBII codes (Universal codes - 4 digits), the codes can be found here: (lots of info too)

Yes,

For all Chrysler vehicles prior to 1996, will use those two digit codes found at web page. It's a built in diagnostic routine that for the most part is standardized over all Chryslers:

Your mechanic uses the same procedure to get the codes (three on-off-on) and then goes and checks the related sensors or circuits that produce that code. I believe the shops also have a Chrysler specific plug in scan tool that retrieves the same info plus a history buffer of old codes. Old codes will age out in 50-75 ignition starts. Disconnecting and reconnecting the battery will reinitialize (reset) the codes and history buffer.

ODB cars (1996+) standardized this diagnostic process thru all car manufacturers and standardized the diagnostic codes.

These cars require an ODBII reader to get the codes (although some models have a different procedure than the "on-off-on" sequence to output the four digit codes. Some models also still support the "on-off-on" method to output the two digit codes too) . All ODBII computers also do not allow the disconnecting - reconnecting the battery trick to reset old codes. The computer must reset the code itself or an old code must age out.

TNPD-if you turn it off and on like that, you coud hurt your fuel injectors and put alot of wear and tair on fuel pump. but if you do that 30 times your cpu will more or less re-boot.

You will not damage your fuel pump or injectors with the key on-off, but if you want all the codes retrieved you need to use a scanner.

No, what i ment was turing it off and on many tims w/o starting the car. thats what i was talking about.
