Toyota Tacoma (2015-2018) Service Manual / Ac60e Automatic Transmission / Transaxle / Automatic Transmission System(for 2gr-fks) / 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.
