DTC CheckS7RS0BA204005
Using SUZUKI Scan Tool1) Prepare SUZUKI scan tool.
2) With ignition switch turned OFF, connect it to data link connector (DLC) located on underside of
instrument panel of driver’s side.
Special tool
(A): SUZUKI scan tool 3) Turn ignition switch ON.
4) Read DTC according to
instructions displayed on
SUZUKI scan tool and print it or write it down.
Refer to SUZUKI scan tool operator’s manual for
further details.
If communication between SUZUKI scan tool and
BCM is not possible, check if SUZUKI scan tool is
communicable by connecting it to BCM in another
vehicle. If communication is possible in this case,
SUZUKI scan tool is in good condition. Then check
data link connector and serial data line (circuit) in the
vehicle with which communica tion was not possible.
5) After completing the check, turn ignition switch off and disconnect SUZUKI scan tool from data link
connector.

DTC TroubleshootingStep Action YesNo
1 DTC check of BCM
Is DTC U0155 (No. 0155) and DTC U1073 (No. 1073)
detected together? Go to “DTC U1073 (No.
1073): Control Module
Communication Bus
Off”.Go to Step 2.
2 Control module connector check
1) Check connection of connectors of all control modules
communicating by means of CAN.
2) Recheck BCM for DTC.
Is DTC U0155 (No. 0155) detected? Go to Step 3.
Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
3 Combination meter power and ground circuit check
1) Turn ignition switch to ON position.
Do warning lights in combi nation meter other than key
indicator light light up? Go to Step 4.
Check combination
meter power and
ground circuit. If circuit
is OK, substitute a
known-good
combination meter and
recheck.
4 CAN communication circuit check
1) Turn ignition switch to OFF position.
2) Disconnect connectors from BCM, combination meter
and steering angle sensor (ESP ® model).
3) Check CAN communication circuit between BCM and combination meter for open, short and high resistance.
Is each CAN communication circuit in good condition? Go to Step 5.
Repair circuit.
5 CAN communication circuit check
1) Disconnect connectors of all control modules
communicating by means of CAN.
2) Check CAN communication circuit between control modules other than Step 4 for open, short and high
resistance.
Is each CAN communication circuit in good condition? Go to Step 6.
Repair circuit.
6 DTC check of BCM
1) Connect connectors of disconnected control modules
communicating by means of CAN.
2) Disconnect connector of any one of control module other than BCM.
3) Recheck BCM for DTC.
Is DTC U0155 (No.0155) detected? Disconnect connectors
of control modules other
than the one whose
connector is
disconnected in Step 2)
one by one and check
that DTC U0155 is
detected by BCM each
time connector is
disconnected. When
DTC U0155 is not
detected by BCM while
checking in this way, go
to description under
“NO” below. If DTC
U0155 is detected by
BCM even when
connectors of all control
modules that use CAN
communication with
BCM are disconnected,
substitute a known-
good BCM and recheck.Check power and
ground circuit of control
module disconnected in
Step 2). If circuit is OK,
substitute a known-
good control module
disconnected in Step 2)
and recheck.
