[FONT="]I couldn't find this on Mud. Thanks to Aaron (Mr 2FE), he put this together some time back. I have had several questions about reading the check engine light on a 3FE lately, so here it is. I'll be adding it to the FAQ.[/FONT] [FONT="] [/FONT] [FONT="]Get a Haynes, Chilton’s, or a Factory Service Manual (FSM)[/FONT] For the FSM call Toyota Publications @ (800) 622-2033 How do you retrieve the codes? It’s easier than you think. Follow the following steps to find out how your engine is running. Initial Conditions: Battery voltage 11 volts or more Throttle valve fully closed (TPS IDL points closed) Transmission in neutral Accessories switched “OFF” Engine at normal operating temperature Turn the ignition switch “ON”. DO NOT START ENGINE Using a jumper wire, connect terminals TE1 and E1 of the check connector. Read the diagnostic code as indicated by the number of flashes of the “Check Engine” warning light. There will be a series of flashes. For example, if your ECU showed an error code 13 you would see one flash a pause and then three more flashes. Then a pause of 2.5 seconds and you would see the single flash again then a short pause then the three flashes again. Have a pen a paper ready to write when the light starts to flash. The codes are in your manual.
