Function Check

WARNING: This page is about a different car, the 2022 Subaru WRX. However, it is still accessible from the selected car via links, so may be relevant.

On Service Menu, click "Function Check" to display the following items.

Panel steering switch check
Push switch
- Pressed SW: Indicates the name of the switch pressed last.
- SW status: "Push" or "Release"
- Pressed count: Indicates the total number of times the switch is pressed after this screen is displayed. The total number is reset if another screen is displayed.
Knob switch
- + direction
  No. of rotations: The number of steps detected per rotation is displayed in the "No. of rotations" box. Here, steps represent the electric signal of the knob switch. The number of steps per rotation depends on the rotation speed. In principle, the higher the speed is, the more steps are detected. However, there are some exceptions. For example, if rotation ends at the beginning of the second unit time frame as follows, actual six steps are regarded as a detection of one step and counted as one step.

For example, if rotation ends at the beginning of the second unit time frame as follows, actual six steps are regarded as a detection of one step and counted as one step.
NOTE:
Turn the rotary switch clockwise or counterclockwise to check that the screen indicates correct status according to the operation. If the screen display does not match the actual operation, the rotary SW may be faulty. Perform inspection for the rotary SW.
Touch switch check
Cursor: Appears when the screen is touched. The cursor disappears when a touching finger is removed.
NOTE:
- The user is touching 2 locations on the screen. If the user is touching 3 locations or more, the cursor appears on the 2 locations that are touched first.
- The Subaru Select Monitor does not have the touch switch check function.
Microphone check
With the microphone input level screen displayed, make sound toward the microphone 1 or microphone 2.

Fluctuate the sound volume to check that the microphone 1 or microphone 2 input level changes accordingly.

If the input level does not become green or the input level does not change even when the sound volume is fluctuated, the microphone 1 or microphone 2 may be faulty.
NOTE:
The microphone input function is enabled while this screen is displayed.
- The sound volume is indicated in eight levels.
  The maximum input volume of microphone is equally divided into eight levels from level 0 to level 7.

Navigation system check (only for models with navigation)

GPS related check: Status of the GPS signal reception can be checked. When there is faulty in reception status, position detection or date indication, re-check the reception status at a location with a fine view and no obstacles around that will interrupt the signal reception. When normal condition is still not obtained, the GPS antenna may be faulty.

GNSS/Reception number: Normal when it is indicated in blue.
GNSS/Status: Normal when OK is indicated.
GNSS/Measurement ratio 3D:
GNSS/Measurement ratio 2D:
GNSS/Date: Normal when current time is indicated. When current date/time is not indicated, click the Date Setting button to set the current date on the displayed date setting screen.
GNSS/Position: Normal when longitude and latitude of the current position are indicated.

SPD check: Status of the vehicle speed sensor signal can be checked.

Before starting inspections, check the safety around the vehicle. (Lift up the vehicle as necessary.)
When VDC Control Module detects DTC, perform the clear memory of [Brake Control] using the Subaru Select Monitor. Ref. to COMMON (DIAGNOSTICS)>CLEAR MEMORY
Drive the vehicle at 9 km/h (6 MPH) or more.
Check that SPD indicates vehicle speed that is almost equivalent to the figure displayed on the combination meter.
Vehicle speed is not displayed. Or, when different vehicle speed is indicated, check if CAN system DTC is stored. If so, perform the diagnosis according to the DTC. When CAN system DTC is not stored, check if the DTC related to the vehicle sensor is stored for the VDC system, and perform inspection according to the procedure. If no fault is found with the CAN system and vehicle speed sensor, and the vehicle speed is displayed on the combination meter, the unit itself may be faulty.

Gyro sensor related check: Status of the Gyro sensor signal can be checked. If fault is found with the Gyro sensor related indications, the main unit could be faulty.

Gyro Sensor/Raw data: Normal when output as indicated in the following table.
Gyro Sensor/Offset: Normal when output as indicated in the following table.
Gyro Sensor/Relative bearing: Normal when output as indicated in the following table.
Angle Sensor/Raw data: Normal when output as indicated in the following table.
Angle Sensor/Relative angle: Normal when output as indicated in the following table.
Gyro/Distance accuracy learning level: Set to "0" at factory setting, and the level increases according to the driving. When the learning level reaches 3 or more (3 or more gray indication), sensor learning is sufficiently completed.
Reset: Press and hold the Reset button for three seconds to reset the pulse count of SPD, relative bearing of Gyro sensor, relative angle of inclined angle sensor.

NOTE:

The following shows information to be displayed and its description.

Item	Display	Contents
GNSS/Reception number NOTE: On this screen, GPS sensor information, which is updated every second, is displayed.	Blue	When notification of "Positioning with collected data is used" is received from the GPS reception device. (Status: In-use)
	Yellow	When notification of "Tracking in progress" is received from the GPS reception device. (Status: Reception in progress)
	Transparent	When notification of "Positioning with collected data is not used" or "Searching in progress" is received from the GPS reception device. (Status: Not used)
GNSS/Status	OK (H3D)	When three-dimensional positioning (Hyper 3D positioning) using satellites with less accuracy degradation is used.
GNSS/Measurement ratio 3D	3D: 70%	Displays ratio of three-dimensional positioning satellites.
GNSS/Measurement ratio 2D	2D: 20%	Displays ratio of two-dimensional positioning satellites.
GNSS/Measurement ratio NG	NG: 10%	Displays ratio of non-positioning satellites.
GNSS/Date	Current date and time	Displays date information obtained from GPS in four digits for year and 24-hour clock for time. Date information is displayed as [Y/M/D].
GNSS/Position (latitude)	Current position, latitude information	Displays latitude information of the current position in "degree", "minute" and "second". When positioning information is not obtained, it appears as 00° 00' 00".
GNSS/Position (longitude)	Current position, longitude information	Displays longitude information of the current position in "degree", "minute" and "second". When positioning information is not obtained, it appears as 00° 00' 00".
SPD/Pulse count	Pulse count	Displays SPD signal status in the following format. The number of input pulses accumulated since this screen is displayed. (Indicated in four-digit DEC code.) The number returns to 0 after 9999. Reset with ACC OFF/ON.
SPD/Speed	Speed	Displays SPD signal status in the following format. LSB: Displays in km-per-hour as 1 [km/h]. Displays 255 [km/h] for MAX value or more, and 0 [km/h] for MIN value or less.
Gyro Sensor/Raw data	deg/sec	Displays the angular speed detected by the Gyro sensor. Updated at 1 sec intervals.
Gyro Sensor/Offset	deg/sec	Displays the angular speed average value detected by the Gyro sensor at the latest point that the vehicle speed became zero. Updated at 1 sec intervals.
Gyro Sensor/Relative bearing	***degrees	Displays the azimuth angle change amount based on the point that the screen changed. The value increases when turning right, and decreases when turning left.
Angle Sensor/Raw data	***G	Displays the inclined angle detected by the angle sensor.
Angle Sensor/Relative angle	***degrees	Displays the inclined angle change amount based on the point that the screen changed.
Gyro/Distance accuracy learning level	Displays the Gyro sensor learning progress. Set to 0 at factory setting, and the level increases according to the driving.	Displays the sensor learning progress to judge if the insufficient sensor compensation could be the cause of the problem, when problems in navigation (such as an incorrect vehicle location) occurred.
