HOW TO USE SUBARU SELECT MONITOR

Note. For detailed operation procedures, refer to "PC application help for Subaru Select Monitor". If VDC and Subaru Select Monitor cannot communicate, check the communication circuit. < Refer to COMMUNICATION FOR INITIALIZING IMPOSSIBLE , INSPECTION, Subaru Select Monitor. >

READ CURRENT DATA

Note. For detailed operation procedures, refer to "PC application help for Subaru Select Monitor". A list of the support data is shown in the following table.

FUNCTION CHECK

FREEZE FRAME DATA

Note. Data stored at the time of trouble occurrence is shown on display. Each time a trouble occurs, the latest information is stored in the freeze frame data in memory. If a freeze frame data is not properly stored in memory (due to a drop in VDCCM power supply, etc.), a DTC suffixed with a question mark "?" appears on the Subaru Select Monitor display. This shows it may be an unreliable reading.

PARAMETER SELECTION

Note. When the VDCCM&H/U is replaced with a replacement part, be sure to perform the parameter selection/registration to the VDCCM&H/U using this function. To confirm the applied model, refer to the "model number plate" attached on the vehicle. < Refer to IDENTIFICATION , Identification. > When the applied model is entered wrong, re-entry is possible. When the registration has not been performed, the DTC code "Parameter selection error" is detected together with the ABS/EBD/VDC warning light illumination.

1. Connect the Subaru Select Monitor.
2. On «Main Menu» display, select {Each System Check}.
3. On «System Selection Menu» display, select {Brake Control System}.
4. When {VDC} is displayed, select the [OK] button.
5. On «Brake Control Diagnosis» display, select {Select Parameter}.
6. Check the applied model and option code indicated in the "Model number plate". < Refer to «IDENTIFICATION»(ref-565149-S16849968182013071000000) , Identification. >
7. Enter the applied model of 7-digit alphanumeric characters and press the [Enter] key.
8. When the option code input screen appears after entering the applied model, enter the option code consisting of 4-digit alphanumeric characters, and press the [Enter] key When the option code is 3 digits, add "0" in front and enter the code as 4 digits.
9. When the confirmation screen indicating the vehicle information appears, check that the correct applied model and grade are displayed and click the [OK] button. NOTE: When the displayed applied model and grade are different from those of the vehicle, perform registration operations again after clicking the [OK] button.
10. Execute the Clear Memory Mode after parameter selection and registration operations because the DTC for "Parameter selection error" is memorized. < Refer to «CLEAR MEMORY MODE»(ref-565192-S30466792462013071000000) . >

PARAMETER CHECK

Note. The parameter data registered in the VDCCM is shown on the display.

1. Connect the Subaru Select Monitor.
2. On the «Main Menu» display, select the {Each System Check}.
3. On the «System Selection Menu» display, select the {Brake Control System}.
4. Click the [OK] button after the {VDC} is displayed.
5. On the «Brake Control Diagnosis» display, select the {Confirm on parameter}.
6. On the {Confirm on parameter} display screen, check that the applied model and grade of the target vehicle are included, and click the [OK] button.
7. If the applied model and grade of the target vehicle are not included on the {Confirm on parameter} display screen, perform parameter selection and registration. < Refer to «PARAMETER SELECTION»(ref-565192-S01648262472013071000000) , OPERATION, Subaru Select Monitor. >
