Monitor
A: BASIC DIAGNOSTIC CHART
If no trouble codes appear in the on-board diag-
nostics operation (although problems have
occurred or are occurring), measure performance
characteristics of sensors, actuators, etc., in the
Subaru Select Monitor and compare with the
?basic data? to determine the cause of problems.
1) Trouble occurs.
2) No trouble codes appear in on-board diagnos-
tics operation.
3) Measure each item using Subaru Select Moni-
tor.
4) Compare measured values with basic data.
5) Determine item which is outside basic data
specifications.
6) Check sensor and actuator affected.
B: BATTERY VOLTAGE
9B1 : CHECK BATTERY VOLTAGE.
1) Turn ignition switch to OFF.
2) Connect Subaru Select Monitor to data link
connector.

3) Start the engine, and engine idling after warm-
up.
4) Turn Subaru Select Monitor switch to ON.
5) Read data of battery voltage using Subaru
Select Monitor.
Battery voltage applied to TCM.
:
Is voltage between 10 and 16 V?
: Go to step VEHICLE SPEED SENSOR
1. <Ref. to 3-2 [T9C0].>
: Check battery voltage and specification
of electrolyte, regulating voltage under
no loads and generator (as a single
unit).
C: CHECK VEHICLE SPEED
SENSOR 1.
9C1 : CHECK VEHICLE SPEED SENSOR 1.
1) Lift-up or raise the vehicle and support with
safety stand.
CAUTION:
On AWD models, raise all wheels off ground.
2) Read data of vehicle speed #1 using Subaru
Select Monitor.
Compare speedometer with Subaru Select
Monitor indications.
Vehicle speed is indicated in ?MPH? or ?km/h?.
NOTE:
The speed difference between front and rear
wheels may light the ABS warning light, but this
indicates no malfunction. When AT control diagno-
sis is finished, perform the ABS memory clearance
procedure of on-board diagnostics system. <Ref.
to 4-4 [T6D2].>
:
Does the speedometer indication
increase as the Subaru Select Moni-
tor data increases?
: Go to step VEHICLE SPEED SENSOR
2. <Ref. to 3-2 [T9D0].>
: Check vehicle speed sensor 1 circuit.
<Ref. to 3-2 [T8R0].>
D: CHECK VEHICLE SPEED
SENSOR 2.
9D1 : CHECK VEHICLE SPEED SENSOR 2.
Read data of vehicle speed #2 using Subaru
Select Monitor.
Compare speedometer with Subaru Select
Monitor indications.
Vehicle speed is indicated in ?MPH? or ?km/h?.
NOTE:
The speed difference between front and rear
wheels may light the ABS warning light, but this
indicates no malfunction. When AT control diagno-
sis is finished, perform the ABS memory clearance
procedure of on-board diagnostics system. <Ref.
to 4-4 [T6D2].>
:
Does the speedometer indication
increase as the Subaru Select Moni-
tor data increases?
: Go to step ENGINE SPEED SIGNAL.
<Ref. to 3-2 [T9E0].>
: Check vehicle speed sensor 2 circuit.
