The good news is that you noticed it... the bad is that it means your
ENGINE has VIOLATED some predetermined thresholds that
TOYOTA MOTORS CORPORATION, notwithstanding their utmost need to sell you yet another vehicle... (
TMC) has deemed it sufficiently dangerous or costly... that they should warn you of your impending
DOOM...
CATACLYSM,
Catastrophe... (etc)
First consider going over the car to check , belts, hoses... fluid levels ... (if you are not very CONFIDENT it might be time to have it towed to your dealer/qualified-mechanic).
Personally... I'd buy a READER... noted below...
Get the manual and save myself a BUCKET of MONEY...
Some of these units are PRETTY CHEAP... but then again they don't do much... you probably want one that can read and write...
Just don't go overboard... look around (think BLUETOOTH) and try to keep the ODB2 UNDER $100
Sure... look at harborfreight.com
(but AMAZON is very competitive w/ awesome return policies)
