Electronic Controlled Automatic Transmission System -- Diagnostic Trouble Code Chart |
If a DTC is displayed during the DTC check, check the parts listed in the table below and proceed to the page given.
- HINT:
- *1: Comes on MIL (Malfunction Indicator Lamp) light up
- *2: "DTC stored" mark means ECM memorizes the malfunction code if the ECM detects the DTC detection condition.
- This DTC may be output when the clutch, brake and gear components etc. inside the automatic transmission are damaged.
