General Description
3. General Description
A: CAUTION
Supplemental Restraint System “Airbag”
The airbag system wiring harness is routed near
the TCM.
CAUTION:
 All airbag system wiring harness and con-
nectors are colored yellow. Do not use an elec-
trical test equipment on these circuit.
 Be careful not to damage the airbag system
wiring harness when performing diagnostics and
servicing the TCM.
Measurement
When measuring the voltage and resistance of
ECM, TCM or each sensor, use a tapered pin with
diameter of less than 0.64 mm (0.025 in) in order to
avoid poor contact. Do not insert the pin more than
0.65 mm (0.026 in).
B: INSPECTION
1. BATTERY
Measure the battery voltage and specific gravity of
electrolyte.
Standard voltage: 12 V or more
Specific gravity: Above 1.260

to OFF.
NOTE:
 For details concerning operation procedure, refer
to the SUBARU SELECT MONITOR OPERATION
MANUAL.
 When {Clear Memory 2} is selected and executed,
DTC and learned control memory is cleared. If Clear
Memory 2 is performed, execute the learning con-
trol. OF LEARNING CONTROL, OPERATION, Subaru

TROL
1) Shift the select lever to “P” range, and apply
parking brake.
2) Lift-up the vehicle.
3) Connect the Subaru Select Monitor to data link
connector, and then turn the ignition switch to ON.
4) Perform the {Clear Memory 2} using Subaru Select
Monitor. ORY MODE, OPERATION, Subaru Select Monitor.>

6) Warm-up the engine until the ATF temperature
which is displayed on the Subaru Select Monitor is
within 60 — 90°C (140 — 194°F). 4AT(H4DOTC)-15, READ CURRENT DATA, OP-
ERATION, Subaru Select Monitor.>
7) Shift the select lever to “R” range.
8) Turn all switches including headlight, air condi-
tioner, seat heater, rear defogger and etc. to OFF.
9) Turn the ignition switch to OFF.
10) Depress the brake pedal fully until the facilitation
of learning control is completed when the “Communi-
cation Failed!” is displayed on Subaru Select Monitor.
11) Turn the ignition switch to ON.
12) Check that the Subaru Select Monitor is re-
turned to normal operation.
13) Shift the select lever to “P” range, and then wait
for more than 3 seconds.14) Shift the select lever to “R” range, and then wait
for more than 3 seconds.
15) Shift the select lever to “N” range, and then wait
for more than 3 seconds.
16) Shift the select lever to “D” range, and then wait
for more than 3 seconds.
17) Shift the select lever to “N” range, and then wait
for more than 3 seconds.
18) Slightly depress the accelerator pedal fully.
19) Slightly release the accelerator pedal fully.
20) Start the engine, and idle it.
21) Shift the select lever to “D” range.
22) Start the facilitation of learning control. At this
time, the POWER indicator light in combination meter
blinks at 2 Hz. When the POWER indicator light does
not blink, turn the ignition switch to OFF and repeat
the procedures from step 4). When the POWER indi-
cator light which blinking at 2 Hz changes to blink at
0.5 Hz, facilitation of learning control is completed.
NOTE:
When blinking of POWER indicator light changes
from 2 Hz to 4 Hz during facilitation of learning con-
trol, repeat the procedure from step 4).
23) Shift the select lever to “N” range, and then turn
the ignition switch to OFF.
24) Shift the select lever to the “P” range, and then
complete the facilitation of learning control.
