Diagnostic Procedure with Diagnostic Trouble Code (DTC)
LAN SYSTEM (DIAGNOSTICS)
10 CHECK HARNESS.
1) Disconnect the harness connector of body
integrated unit.
2) Measure the resistance between harness
connector terminals.
Connector & terminal
(B280) No. 20 — No. 30:
Is the resistance more than 30
M
Ω ?
Open circuit in
related line of body
integrated unit.
Repair the open
circuit of harness
or replace har-
ness. Go to step
11
.
11 CHECK HARNESS.
1) Disconnect the VDCCM (B310) connector.
2) Measure the resistance between harness
connector terminals.
Connector & terminal
(B310) No. 13 — No. 29:
Is the resistance between 115
— 125
Ω
?
Go to step
12
. Go to step
13
.
12 CHECK VDCCM.
1) Disconnect the VDCCM (B310) connector.
2) Measure the resistance between VDCCM
terminals.
Connector & terminal
(B310) No. 20 — No. 34:
Is the resistance between 115
— 125
Ω
?
Go to step 13 . Open circuit in end
resistance of
VDCCM. Replace
the VDCCM. <Ref.
to VDC-8, VDC
Control Module
and Hydraulic Con-
trol Unit
(VDCCM&H/U).>
13 CHECK ECM.
1) Disconnect the ECM connector (B136).
2) Measure the resistance between ECM con-
nector terminals.
Connector & terminal
(B136) No. 27 — No. 35:
Is the resistance between 115
— 125
Ω
?
Repair or replace
the open circuit of
harness connec-
tor. Open circuit in end
resistance of ECM.
Replace the ECM.
<Ref. to
FU(H6DO)-33,
Engine Control
Module (ECM).>
14 CHECK HARNESS.
1) Disconnect the body integrated unit connec-
tor (B280).
2) Measure the resistance between body inte-
grated unit connector and chassis ground.
Connector & terminal
(B280) No. 20 — Chassis ground:
(B280) No. 30 — Chassis ground:
Is the resistance less than 10
Ω
?
Repair or replace
the ground short
circuit of the har-
ness. Go to step 15 .
15 CHECK HARNESS.
1) Disconnect the body integrated unit connec-
tor (B280).
2) Measure the voltage between body inte-
grated unit connector and chassis ground.
Connector & terminal
(B280) No. 20 (+) — Chassis ground (–):
(B280) No. 30 (+) — Chassis ground (–):
Is the voltage 6 V or more? Repair the short
circuit of harness
or replace har-
ness. Go to step
16
.
16 CHECK DTC.
Read the DTC of ECM using the Subaru Select
Monitor. <Ref. to EN(H6DO)(diag)-37, OPERA-
TION, Read Diagnostic Trouble Code (DTC).>
Is DTC other than “CAN com-
munication” displayed? Perform the diag-
nosis according to
DTC. Go to step 17 .
17 CHECK DTC.
Read the DTC of VDCCM using the Subaru
Select Monitor. <Ref. to VDC(diag)-15, READ
DIAGNOSTIC TROUBLE CODE (DTC),
OPERATION, Subaru Select Monitor.>
Is DTC other than “CAN com-
munication” or “C0057” dis-
played? Perform the diag-
nosis according to
DTC. Go to step 1 8 .
1 8 CHECK DTC.
Read the DTC of TCM using the Subaru Select
Monitor. <Ref. to 5AT(diag)-15, OPERATION,
Subaru Select Monitor.>
Is DTC other than “CAN com-
munication” displayed? Perform the diag-
nosis according to
DTC. Replace the body
integrated unit.
