DIAGNOSTIC TROUBLE CODE CHART
NOTICE:
When removing the part, turn the ignition switch OFF.
HINT:
Using SST 09843 −18020, connect the terminals Tc and E1, and remove the short pin.
If any abnormality is not found when inspection parts, inspect the ECU.
If a malfunction code is displayed during the DTC check, check the circu\
it listed that the code. For details
of each code, turn to the page referred to under the ”See page” for respective ”DTC N\
o.” in the DTC chart.
