Reading of codes of malfunctions (DTC) With use of the firm diagnostic Subaru (SSM) scanner SSM is intended for reading of codes of malfunctions (DTC) and the current data, and also for cleaning of memory of the processor of the module of management. Prepare SSM. Connect to it a diagnostic cable and insert a cartridge. Connect SSM to the diagnostic DLC socket located at the left under the dashboard.
Include ignition (the engine do not start). Include power supply of the SSM scanner. In the main menu (MAIN MENU) choose the subsection "Each System Check" and press the YES key. Further, in the field of a choice of system {System Selection Menu} select item {Transmission Control System} and again press the YES button. After a conclusion of data on the AT type press "YES" once again. In the field {Transmission Diagnosis} select item { Diagnostic Code (s) of Display } and press the YES key. Further make a choice like the output data: the last kept codes ({ Latest Diagnostic Code (s) }), or the complete list of the codes which are stored in memory of the processor ({ Memorized Diagnostic Code (s) }), - confirm a choice with pressing of the YES key.
Reading of the current data In the field {Transmission Diagnosis} select item {Current Data Display & Save} (To show and keep the current data) and press the YES button. Further, in the menu of a conclusion of data {Data Display Menu} select item {Data Display} and press the YES button. For display of the necessary data move according to the list by means of scrolling buttons.
The list of the output data is presented in the table given below. Without application of SSM (on the light POWER indicator) Warm up the engine up to the normal working temperature, then switch off ignition and again start the engine. Make a small trip with a speed not less than 20 km/h. Park the car and at the squeezed-out pedal of a foot brake transfer the AT selector lever to the situation "1". Switch off and again include ignition. Make the following switchings of the lever of the selector: "2" — "1" — "2" — "3" — "D". If the indicator at the included blinks with a frequency of 4 Hz (one gleam each 0.125 (1/8) seconds), check a condition of chains of giving of food and grounding. Otherwise pass to the following stage of check. Switch off ignition: if the frequency of a blinking of the indicator makes 2 Hz (one gleam each 0.25 (1/4) seconds), therefore, AT as it should be. Otherwise pass to the following stage of check. If the indicator highlights the DTC codes brought in memory of the processor, copy the output data. If the alarm indicator continues to burn, check its chain for existence of signs of short circuit, make necessary corrections.
Cleaning of memory of the processor With application of SSM In the main menu (MAIN MENU) select item {Each System Check} and press the YES key. Then in the field by {System Selection Menu} choose {Transmission Control System} and press the YES button. After a conclusion to the screen of the monitor of data on the AT type press the YES key once again. In the field {Transmission Diagnosis} (Transmission diagnostics) select item {Clear Memory} and press the YES button. After a conclusion of messages of "Done" and "Turn Ignition Switch Off" switch off SSM and ignition.
Without application of SSM Removal of the codes displayed the display is made by ignition switching off. Nevertheless, previous flowing codes remain written down in memory of the TCM processor food on which moves from a reserve source. For full cleaning of memory it is necessary to take a minimum for one minute the safety lock No. 4 included in a chain of the reserve power supply under the dashboard on the right/at the left.
