  1. When ATF temperature is high

AT OIL TEMP light illuminates when the ATF temperature is abnormally high with engine ON.

  1. When malfunction is detected

AT OIL TEMP light blinks at 2 Hz when the TCM detects the malfunction of CVT with engine ON. In this case, inspect using "Diagnostic Procedure with Diagnostic Trouble Code (DTC)". Ref. to DIAGNOSTIC PROCEDURE WITH DIAGNOSTIC TROUBLE CODE (DTC) .

  1. When AT learning is not finished

AT OIL TEMP light repeats "Blinking at 4 Hz --> Turning OFF" every two seconds, when the AT learning is not finished with engine ON. In this case, perform the "Learning". (During AT learning, the light blinks at 2 Hz or illuminates.) Ref. to LEARNING CONTROL .
