Reading of codes of malfunctions (DTC)


With application of firm diagnostic scanner Subaru (SSM)

SSM it is intended for reading of codes of malfunctions (DTC) and the current data, and also for clearing 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 located at the left under the panel of devices to diagnostic socket DLC.

 Socket DLC is intended ONLY FOR connection of scanners SSM and GST (the standard input reader for systems of onboard self-diagnostics OBD-II)!


Include ignition (the engine do not start).

Include scanner SSM food.

In the main menu (MAIN MENU) choose subsection Each System Check and press a key YES. Further, in the field of a system choice {System Selection Menu} choose point {Transmission Control System} and again press button "YES". After a conclusion of data on type АТ press YES once again.

In the field {Transmission Diagnosis} choose point {Diagnostic Code (s) Display} and press a key YES.

Further make a choice of type of the deduced data: last kept codes ({Latest Diagnostic Code (s)}), or the full list stored in memory of the processor of codes ({Memorized Diagnostic Code (s)}), - confirm a choice with key pressing YES.

 More detailed description of procedure of reading DTC by means of SSM can be found in the instruction on scanner application.


Reading of the current data

In the field {Transmission Diagnosis} choose point {Current Data Display and Save} (to Show and keep the current data) and press button "YES". Further, in the menu of a conclusion of the data {Data Display Menu} choose point {Data Display} and press button "YES". For display of the necessary data move under the list by means of scrolling buttons.

 More detailed description of procedure of reading of the current data by means of SSM can be found in the instruction on scanner application.


The list of the deduced data is presented in the table resulted more low.

Without application SSM (on light indicator "POWER")

Warm up the engine to 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 translate selector AT lever in position 1. Switch off and again include ignition.

Make following switchings of the lever of the selector: 2 — 1 — 2 — 3 — D.

If the indicator at the included blinks with frequency of 4 Hz (one gleam everyone 0.125 (1/8) seconds), check up a condition of chains of giving of a food and grounding. Otherwise pass to a following stage of check.

Switch off ignition: if frequency of a blinking of the indicator makes 2 Hz (one gleam everyone 0.25 (1/4) seconds), hence, АТ as it should be. Otherwise pass to a following stage of check. If the indicator highlights brought in memory of the processor codes DTC, copy the deduced data. If the alarm indicator continues to burn, check up its chain on presence of signs of short circuit, make necessary corrections.

 


Clearing of memory of the processor


With application SSM

In the main menu (MAIN MENU) choose point {Each System Check} and press a key YES. Then in the field {System Selection Menu} choose {Transmission Control System} and press button "YES". After a conclusion to the screen of the monitor of the data about type АТ press a key YES once again.

In the field {Transmission Diagnosis} (transmission Diagnostics) choose point {Clear Memory} and press button "YES".

After a conclusion of messages Done and Turn Ignition Switch Off switch off SSM and ignition.

 More detailed description of procedure of clearing of memory by means of SSM can be found in the instruction on scanner application.


Without application SSM


Removal of the displayed display of codes is made by ignition deenergizing.

Nevertheless, previous flowing codes remain written down in memory of processor TCM a food on which moves from a reserve source. For full clearing of memory it is necessary to take a minimum for one minute included in a chain of the reserve power supply a safety lock № 4 on the right/at the left under the panel of devices.
