DIAGNOSTIC TROUBLE CODE CHART
If a DTC is displayed during the DTC check, check the circuit listed in the table below and proceed to the page given.
HINT:
- *1: "Comes on" means that the MIL will illuminate.
- *2: "DTC stored" means that the ECM memorizes the malfunction code if the DTC detection condition(s) are met.
- These DTCs may be output when the clutch, brake and gear components, etc., inside the automatic transmission are damaged.
