Diagnostic Aids

WARNING: This page is about a different car, the 2003 Toyota 4Runner. However, it is still accessible from the selected car via links, so may be relevant.

This DTC diagnosis & repair procedure assumes the premise that the engine starts normally. If DTC is present and a no start condition exists, proceed to BASIC DIAGNOSTIC PROCEDURES - V6 & V8 article.

Using Toyota hand-held tester or scan tool, read FREEZE FRAME data. Freeze frame data records engine conditions when malfunction is detected.
