ENGINE (DIAGNOSTICS)

SUBARU SELECT MONITOR

Front Wheel Speed

Display: 0 — 255 km/h (0 — 158 MPH)

The front wheel speed is displayed. This signal is
used for the shift control, lock-up control, line pres-
sure control, and transfer control. 

ATF Temp.

Display: 

−−−−

40 to 215

°°°°

C (

−−−−

40 to 419

°°°°

F)

The ATF temperature via the signal from the ATF
temperature sensor is displayed. 

Gear Position

Display: 

The present gear position is displayed. The gear
position is calculated from the engine speed and
torque converter turbine speed. 

Line Pressure Duty Ratio

Display: 0 — 123%

The duty value of the line pressure duty solenoid is
displayed. The line pressure duty solenoid is regu-
lated by the TCM, adjusting the line pressure to the
optimum value depending on driving conditions. 

Lock Up Duty Ratio

Display: 0 — 123%

The duty value of the lock-up duty solenoid is dis-
played. The lock-up duty solenoid is regulated by
the TCM. Because the lock-up duty solenoid con-
trols the lock-up control valve, the lock-up clutch
engages and disengages smoothly. 

Transfer Duty Ratio

Display: 0 — 123%

The duty value of the transfer duty solenoid is dis-
played. The transfer duty solenoid is regulated by
the TCM, adjusting the transfer clutch oil pressure
and controlling the driving force of the rear wheels. 

Turbine Revolution Speed

Display: 0 — 8,160 rpm

The input shaft speed detected by the torque con-
verter speed sensor is displayed. This signal is
used to control the line pressure and 2 - 4 brake
pressure control timing during shifting. 

Throttle Sensor Power

Display: 0 — 256 V

The supply voltage to the throttle sensor is dis-
played. This signal is used for the throttle sensor
output correction. 

Brake Clutch Duty Ratio

Display: 0 — 123%

The duty value of the 2 - 4 brake duty solenoid. The
2 - 4 brake duty solenoid is regulated by the TCM,
adjusting the 2 - 4 brake pressure during shifting
and relieving from harsh shifting. 

Rear Wheel Speed

Display: 0 — 255 km/h (0 — 158 MPH)

The rear wheel speed is displayed. This signal is
used to control the transfer. If the front vehicle
speed sensor is malfunctioning, this signal is used
as a substitute. 

Cruise Control Signal

Display: ON or OFF

When the cruise control switch is ON, ON is dis-
played. When OFF, OFF is displayed. 

ABS Signal

Display: ON or OFF

When the ABS function is active, ON is displayed.
When inactive, OFF is displayed. 

Stop Light Signal

Display: ON or OFF

When the brake pedal is depressed, ON is dis-
played. When released, OFF is displayed. 

1st, 2nd, 3rd, D, R, Range Signal

Display: ON or OFF

When the switch for each range is ON, ON is dis-
played. 

2-4 Brake Timing Sol.

Display: ON or OFF

When the 2-4 brake timing solenoid is ON, ON is
displayed. When OFF, OFF is displayed. The 2-4
brake timing solenoid is regulated by the TCM, con-
trolling the release timing of the 2-4 brake. 

Low Clutch Timing Sol.

Display: ON or OFF

When the low clutch timing solenoid is ON, ON is
displayed. When OFF, OFF is displayed. The low
clutch timing solenoid is regulated by the TCM,
controlling the release timing of the low clutch. 

Shift Solenoid #1, #2

Display: ON or OFF

When the solenoid valve is ON, ON is displayed.
When OFF, OFF is displayed. By combining No. 1
and No. 2 solenoids, the shifting mechanism is con-
trolled. 

P Range

Display: ON or OFF

When the shift lever stays in P range, ON is dis-
played. When not in P range, OFF is displayed. 

N Range

Display: ON or OFF

When the shift lever stays in N range, ON is dis-
played. When not in N range, OFF is displayed.

Torque Control Signal #1, #2

Display: ON or OFF

When the torque down signal exists, ON is dis-
played. When it does not exist, OFF is displayed. 

Torque Permission Signal

Display: ON or OFF

The signal which notifies whether or not torque
down is possible is displayed. This signal is trans-
mitted from the ECU in response to a torque down
signal from the TCU. When torque down is prohib-
ited, ON is displayed. When permitted, OFF is dis-
played.
