Hi All:
___The acronyms posted are the bread and butter of any automobile enthusiast.
CEL: Check Engine Light or sometimes referred to as a MIL: Malfunction Indicator light
CAT: Catalytic Converter
OBD-II: On Board Diagnostic. This is the actual output of some of the sensors telling the ECU computer what is going on with your car.
Scan Tool: A serial interface electronic tool (PC, Laptop, Palm, PDA) that attaches to your cars OBD-II port and reads the codes or data in real time. SW varies but can be as limited as reading a few codes to reading everything and allowing manipulation in real time for diagnostics reasons. You can also clear codes (CEL) if the actual parameter has dropped back into its non-problematic pre-determined range.
___Good Luck
