Pulse Sensor and Its Circuit Inspection
(Pinching Prevention Function Model)
S6RW0D9506029
NOTE
After replacing or disconnecting the driver
side power window regulator (motor), power
window main switch, battery and/or fuse,
make sure to execute the initial setting, (to
have the door glass closed position learned)
refer to “Power Window Main Switch
Initialization (Pinching Prevention Function
Model)”.

Pulse Sensor Circuit Diagram1) Remove driver side door trim referring to Step 1) to
3) of “Front Door Glass Removal and Installation”.
2) Remove power window main switch from driver side
door trim, and them connect connector to power
window main switch.
3) Disconnect power window motor connector.
4) Turn ignition switch to ON position.
5) Check that “SV” wire terminal voltage of power
window motor connector is 10 – 14 V. If voltage is
not satisfied, check power window main switch
circuit for open, short and high resistance. If circuit is
OK, replace power window main switch.
6) Connect power window motor connector.
7) Connect oscilloscope to power window main switch
connector terminals.
8) Check pulse sensor signal by using oscilloscope. If
pulse sensor signal is not satisfied, check pulse
sensor 1 and 2 circuit. If circuit is OK, replace door
window regulator (motor).

CAUTION!
• After replacing or disconnecting the driver
side door window regulator (motor), power
window main switch, battery or fuse, be
sure to execute initial setting (to have door

If initial setting is not executed, correct
automatic operation (including pinching
prevention operation) would not be
available.
• Make sure that no foreign matter is
pinched while executing initial setting.

1) Open driver side door glass fully.
2) Raise driver side door window switch (MANUAL UP
position) of power window main switch until door
glass is closed completely and hold the switch in that
state for 2 seconds or more.3) Use auto-down / auto-up function of power window
main switch and check that door glass opens fully /
closes completely.
4) Check pinching prevention function referring to
“Inspection of Pinching Prevention Function
(Pinching Prevention Function Model)”.

Precautions
Precautions in Diagnosing TroublesS6RW0DA300001
• Before confirming the diagnostic trouble code (DTC),
do not disconnect connector from ECM, battery cable
from battery, ground wire harness, or main fuse. Such
disconnection will erase DTC stored in ECM.
• DTC stored in ECM memory can be checked as well
as cleared by using SUZUKI scan tool. Before using
SUZUKI scan tool, read its operator’s manual
carefully to know how to use it and what functions are
available.
• Be sure to read “Precautions for Electrical Circuit
Service in Section 00” before inspection.
• Communication of ECM, BCM, ABS control module,
TCM (if equipped), 4WD control module (if equipped),
keyless start control module (if equipped),
combination meter and DLC is established by CAN
(Controller Area Network). Therefore, handle CAN
communication lines with care referring to “Precaution
for CAN Communication System in Section 00”.
For CAN communication system, refer to description
on “CAN Communication System Description in
Section 1A”.
Precaution in Replacing ECMS6RW0DA300002
• If ECM is replaced with new or used one without
Immobilizer control function, the engine will not be
started. In case of the above, check if the newly
installed ECM has Immobilizer control function.
• After ECM is replaced with new one or used one, the
transponder code in the transponder built in the
ignition key has to be registered with ECM. Or, the
engine cannot be started up. For the registration
procedure, refer to “Procedure after ECM
Replacement”.
Precaution in Replacing Ignition KeyS6RW0DA300003
To register ignition key in case of replacing key(s) and/or
making spare key(s), the transponder code in the ignition
key is registered with ECM. Or the engine can not be
started up. For the registration procedure, refer to
“Registration of the Ignition Key”.
Precautions in Handling Immobilizer Control
System
S6RW0DA300004
• Do not turn ON ignition switch with ignition key in
contact with another one or quite close to another
one. Or, the immobilizer control system may detect
some abnormal condition and prevent the engine from
starting.
• Do not turn ON ignition switch by using ignition key
with any type of metal (1) wrapped its grip or in
contact with it. Or, the immobilizer control system may
detect some abnormal condition and prevent the
engine from starting.
