Toyota is pretty standard with reading code. Most of the trouble codes apply to a majority of its line of cars. Locating the diagnostic plug will give access to pulling your trouble codes. This is found in the engine bay of the vehicle. By using a jumper wire, connect pin E1 and T1 or TE1 (Some vehicles will have pin TE1 instead of T1) and put the vehicle in the "ON"-position. Make sure that all accessories are off and the vehicle is in neutral.

One difference of reading Toyota's code is rather than long pulses to represent digits of 10, Toyota uses short pulses to represent the first digit and uses short pulses again to represent the second digit in a two-digit number. If a vehicle has more than one code, there will be a two-second pause between flashes. This signifies that a new code is going to be revealed. If a repeated code comes up, this signifies that the string of code is starting again.
