Lexus IS250 IS220d GSE20 ALE20 - A960E AUTOMATIC TRANSMISSION


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.
