Abbreviations

[ozarkboy]

This is the problem: I graduated from the world of 1972 GMC pickup and a !965 Volvo, both with carburetors and single point ignition, to the world of electronic eveything with no catching up in the middle. If someone would take the time to post a list of all the commonly used abbreviations such as ECM and ECR, etc., it would be much appreciated by this farmboy mechanic.

Thanks Ranger88den and Schoner. I put the list on file and added a printed copy to my growing reference notebook. At sixty-five years old I hope I have enough years left to learn some of this stuff. I probably should start saving my money and find a good honest well-trained mechanic. I've been reading all the posts in the Sidekick section of this forum and this list will definitely make it more understandable.

CEL - Check Engine Light
SES - Service Engine Soon light
OME - Old Man Emu (lift manufacturer)
RRO - Rocky Road Outfitters (lift manufacturer, reseller)

Thanks, Rotten Bob. Every little bit helps. We're almost neighbors. I live in Port Angeles.

Cool. I've been to Port Angeles a few times; nice town. I go hiking or camping on the peninsula at least twice a year, and that usually involves driving through Port Angeles.

Just thought of two more that I've come across on various forums:

FSM - Factory Service Manual
PO - Previous Owner

Hey ozark,

Some things haven't changed. Some of us still write NFG on defective parts!

Happy learning! It's easier than you think to understand this stuff.
