1
CHECK HARNESS.
1) Disconnect the TCM connector.
2) Measure the resistance between TCM con-
nector terminals.
Connector & terminal
4AT model
(B54) No. 3 — No. 12:

(B54) No. 3 — No. 4:
Is the resistance
∞ Ω?
Open harness in
related lines of
TCM. Repair or
replace the open
circuit of harness.
2
CHECK TCM.
Read the DTC of TCM using Subaru Select
Monitor. <Ref. to 4AT(diag)-16, READ DIAG-
NOSTIC TROUBLE CODE (DTC), OPERA-
TION, Subaru Select Monitor.> <Ref. to
5AT(diag)-17, READ DIAGNOSTIC TROUBLE
CODE (DTC), OPERATION, Subaru Select
Monitor.>
Is DTC other than “CAN com-
munication” displayed on Sub-
aru Select Monitor?
Perform the diag-
nosis according to
DTC.
Replace the TCM.

2
CHECK HARNESS.
1) Disconnect the body integrated module
connector.
2) Measure the resistance between body inte-
grated module connector terminals.
Connector & terminal
(B280) No. 20 — No. 30:
Is the resistance 115 — 125
Ω?
3
CHECK HARNESS.
1) Disconnect the body integrated module
connector.
2) Measure the resistance between body inte-
grated module connector and chassis ground.
Connector & terminal
(B280) No. 20 — Chassis ground:
(B280) No. 30 — Chassis ground:
Is the resistance
∞ Ω?
Open harness on
related line of body
integrated mod-
ule. Repair or
replace the open
circuit of harness.
4
CHECK HARNESS.
1) Disconnect the body integrated module
connector.
2) Measure the voltage between body inte-
grated module connector and chassis ground.
(Ignition switch ON)
Connector & terminal
(B280) No. 20 (+) — Chassis ground (
−
):
