Problem Symptoms Table
WARNING: This page is about a different car, the 2006 Toyota 4Runner. However, it is still accessible from the selected car via links, so may be relevant.
If a normal code is displayed during the DTC check but the problem still occurs, check the circuits for each problem symptom in the order given in PROBLEM SYMPTOMS TABLE and proceed to the reference.
