I've seen the triangle of death with a check engine light and a hybrid system warning light all at once. They all went away after 3 days and the car appears to be operating normally with 58K miles (classis '02). I've spent hours reading any post I thought would pertain to my situation and I regulary see people pulling codes and referencing the numbers. Are these shop techs with access to expensive toyota equipment or is there something out there a DIY comsumer could purchase? If so, would it work to pull codes from my Tundra as well? I'm guessing the codes are broken down in an OEM service manual rather than the Haynes version I've used since high school.?.?.
