Diagnostic Trouble Code Chart

HINT:

• Using SST 09843-18040, connect terminals Tc and CG of the DLC3.
• If no abnormalities are found when inspecting the parts, inspect the ECU and wire harness.
• If a malfunction code is displayed during the DTC check, check the circuit listed for the code. For details of each code, refer to the link given under the respective "DTC No." in the following DTC chart.
