Diagnostic Aids

WARNING: This page is about a different car, the 2003 Lexus GX 470. However, it is still accessible from the selected car via links, so may be relevant.

Read freeze frame data using hand-held tester or OBD-II scan tool, as freeze frame data records engine conditions when a malfunction is detected. When troubleshooting, this is useful for determining whether vehicle was running or stopped, engine was warmed up or not, or air-fuel ratio was lean or rich at time of malfunction.
