OPERATION

1. HOW TO USE SUBARU SELECT MONITOR

1. Prepare the Subaru Select Monitor kit.

2. Connect the diagnosis cable to the Subaru Select Monitor.

3. Insert the cartridge to the Subaru Select Monitor.

4. Connect the Subaru Select Monitor to the data link connector.

(1) Data link connector is located in the lower portion of instrument panel (on the driver’s side).

(2) Connect the diagnosis cable to the data link connector.

CAUTION:

Do not connect any scan tools except the Subaru Select Monitor or general scan tool.

5. Turn the ignition switch to ON (engine OFF) and Subaru Select Monitor switch to ON.

(A)

Power switch

6. Using the Subaru Select Monitor, call up DTC and data, then record them.

2. READ DIAGNOSTIC TROUBLE CODE (DTC) FOR ENGINE (NORMAL MODE)

Refer to “Read Diagnostic Trouble Code” for information about how to display a DTC.

3. READ DIAGNOSTIC TROUBLE CODE (DTC) FOR ENGINE (OBD MODE)

Refer to “Read Diagnostic Trouble Code” for information about how to display a DTC.

4. READ CURRENT DATA FOR ENGINE (NORMAL MODE)

1. On the «Main Menu» display screen, select {Each System Check} and press the [YES] key.

2. On the «System Selection Menu» display screen, select {Engine Control System} and press the [YES] key.

3. Press the [YES] key after the information of engine type has been displayed.

4. On the «Engine Diagnosis» display screen, select the {Current Data Display/Save}, and then press the [YES] key.

5. On the «Display Menu» screen, select the {Data Display} and press the [YES] key.

6. Using the scroll key, scroll the display screen up or down until the desired data is shown.
