Scan Tool DataS7RS0B5104009
As the data values given in the following table are standard values estimated on the basis of values obtained from the
normally operating vehicles by using a scan tool, use them as reference values. Even when the vehicle is in good
condition, there may be cases where the checked value does not fall within each specified data range. Therefore,
judgment as abnormal should not be made by checking with these data alone.
Also, condition in the following table that can be checked by the scan tool are those detected by TCM and output from
TCM as commands and there may be cases where the auto matic transaxle or actuator is not operating (in the
condition) as indicated by the scan tool.
NOTE
The following scan tool data related to automatic transaxle can be checked only by communicating
with TCM.

General Description
Key Coding ConstructionS7RS0B9601001
Key Usage and Identification
Key is used for ignition and door lock cylinders. Key is cut on both edges to make them reversible.
Key identification is obtained from five character key code stamped on key code tag. Using this key code, key code
cutting combination can be determined from a code list (ava ilable to owners of key cutting equipment from suppliers).
Rear End Door Opener System DescriptionS7RS0B9601002
Rear end door opener system consists of rear end door opener switch (1), rear end door opener relay (in BCM), rear
end door lock assembly (2) and BCM (3) (in junction block assembly).
Rear end door opener system is activated by pushing re ar end door opener switch after all doors are unlocked by
manual door switch, key cylinder s witch, keyless entry transmitter or request switch (5) (if equipped).
When rear end door opener switch pushed rear end door opener relay is ON. Then, BCM releases latch of rear end
door lock assembly from striker and rear end door can be opened.
In addition, in case that rear end door cannot be opened by rear end door opener switch, rear end door can be opened
by emergency lever (4) in rear end door lock assembly.

Keyless Entry System Operation InspectionS7RS0B9604004
NOTE
When performing the this inspection, make
sure to have any of the door once opened/
closed after the ignition key has been
removed from the ignition key cylinder.

1) Confirm that power door lock system operates normally, refer to “Power Door Lock System
Operation Inspection”.
2) All doors are closed and unlocked.
3) Check the following operation: a) Push “lock” button (1 ) on transmitter (2) or
remote controller once, and check all doors lock
and hazard waning lights flash once.
b) Push “unlock” button (3) on transmitter (2) or remote controller twice, and check all doors
unlock and hazard waning lights flash twice and
interior light turns on several seconds with the
interior light switch in the middle position. If malfunction is found, go to “Keyless Entry System
Symptom Diagnosis (If Equipped)”.
Door Lock Function of Keyless Start System
Symptom Diagnosis (If Equipped)
S7RS0B9604005
Proceed to “Keyless Start System Symptom Diagnosis in
Section 10E” in case that doors cannot be locked and
unlocked by operating the request switch at the outside
door handle.
Rear End Door Opener System Symptom DiagnosisS7RS0B9604006
NOTE
• Use of SUZUKI scan tool makes it easy to check wh
ether a faulty condition is on the input side or
output side of BCM. For checking procedure, re fer to “Diagnosis Using Output Test Function of
SUZUKI Scan Tool” under “Scan Tool Data in Section 10B”.
• Check each part in the order from the top of the following list.

Rear End Door Opener System Operation InspectionS7RS0B9604007
1) Unlock all doors by using manu al lock switch, keyless entry transmitter, or key cylinder switch.
2) Make sure that latch of rear end door is released from striker when rear end door opener switch is pushed. If malfunction is found, go to “Rear End Door Opener System Symptom Diagnosis”.
