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 chart is based on the premise that the engine is cranked normally. If the engine does not crank, proceed to BASIC DIAGNOSTIC PROCEDURES - V6 & V8 article.
Read freeze frame data using the hand-held tester or the OBD II scan tool, as freeze frame data records the engine conditions when a malfunction is detected.
