Inspection Procedure

WARNING: This page is about a different car, the 2008 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: When replacing the brake actuator assembly, perform zero point calibration (See CALIBRATION ).

CHECK CAN COMMUNICATION SYSTEM

Check if the CAN communication system DTC is output (See DIAGNOSIS SYSTEM ).
