Diagnostic Trouble Code Chart
WARNING: This page is about a different car, the 2002 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
When replacing the steering angle sensor or ECU, make sure to perform steering angle sensor zero point calibration.
CAUTION:
- When removing the part, turn the ignition switch OFF.
NOTE:
- Using SST 09843-18020, connect the terminals Tc and E1.
- If any abnormality is not found when inspecting parts, inspect the ECU.
- If a malfunction code is displayed during the DTC check, check the circuit corresponding the code. For details of each code, refer to the procedure under respective "DTC No." in the DTC chart.
