Inspection Procedure

WARNING: This page is about a different car, the 2009 Toyota Tacoma. However, it is still accessible from the selected car via links, so may be relevant.

When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

Connect the Techstream to the DLC3.
Turn the ignition switch to ON.
Turn the Techstream ON.
Enter the following menus: Powertrain/Engine and ECT/Trouble Codes.
