For detailed operation procedures, refer to "PC application help for Subaru Select Monitor".

Note. For details concerning DTC, refer to List of Diagnostic Trouble Code (DTC). Refer to LIST OF DIAGNOSTIC TROUBLE CODE (DTC) .

For detailed operation procedures, refer to "PC application help for Subaru Select Monitor".

Note. If {Clear Memories 2} is executed, DTCs and learned control memory are cleared. If {Clear Memories 2} is executed, perform learning. Refer to LEARNING CONTROL .

GENERAL DESCRIPTION

  1. Follow the messages displayed on the Subaru Select Monitor when working.
  2. When the following work is performed, perform learning for the transmission.

Replacement of TCM/Replacement or disassembly of transmission assembly/Replacement of control valve body/Performing "Clear Memories 2".

When any on-board diagnostics item is malfunctioning, or the learning has not yet completed, AT OIL TEMP light blinks. Blinking continues from the engine start to the ignition switch OFF. The faulty parts or unit can be identified by reading DTCs. Problems which occurred previously can also be identified through the memory function. If the AT OIL TEMP light does not blink although a problem is occurring, the problem can be determined by checking the performance characteristics of each sensor using the Subaru Select Monitor. If the learning has not yet completed, «Learning not completed» is displayed when the Subaru Select Monitor is connected while AT OIL TEMP light is blinking. The AT OIL TEMP light blinking will go off, when the learning is performed. Indicator light signal patterns are as shown in the figure.

Scheme 764

Scheme 764: OPERATION

When the AT OIL TEMP light does not operate normally, check the AT OIL TEMP light circuit. Refer to INSPECTION .

AWD warning light illuminates or blinks at start, or when AWD is faulty.

Scheme 765

Scheme 765: OPERATION
  1. Normal AWD light always illuminates when the ignition switch is ON (engine OFF). Light goes off after two seconds from engine ON.
  2. Faulty AWD warning light blinks at 2 Hz, when tires with different diameters are installed, or when the vehicle is driven with air pressure of any of the four tires significantly low. If the AWD light does not illuminate, or illumination patterns are not as above, check the AWD light circuit. Refer to «INSPECTION»(ref-565205-S06491079022013071000000) .
