Toyota Tacoma (2015-2018) Service Manual: Diagnostic Trouble Code Chart
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 "See page" given.
- *1: "Comes on" means the Malfunction Indicator Lamp (MIL) illuminates.
- *2: "DTC stored" means the ECM memorizes the trouble code if the ECM detects the DTC detection condition.
- These DTCs may be output when the clutches, brakes, gear components, etc., inside the automatic transmission are damaged.
