Problem Symptoms Table
WARNING: This page is about a different car, the 2006 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
If a normal code is displayed while checking DTCs but the problem still occurs, check the circuits for each problem symptom in the order given in PROBLEM SYMPTOMS CHART .
CRUISE CONTROL SYSTEM:
