Theft Deterrent LightS7RS0BA201003
The information display or clock (1) of this vehicle includes a theft deterrent light (2) for the theft preventive purpose.
The BCM makes the theft deterrent light flash at certain interval s after the ignition switch is turned off until it is turned
on again. Also, to check DTCs stored in BCM without usin g a SUZUKI scan tool when diagnosing troubles, it is
possible to identify them by flashing patterns of the theft deterrent light.
Security Alarm Description (If Equipped)S7RS0BA201004
Operation
The security alarm system provides a warning of an abnormal condition to those who are around. Its operation is as
follows. While the system is in the stand- by mode (when 20 seconds or more elapsed after the door is locked using a
keyless entry transmitter or door request switch), BCM monitors door lock status, door switch status and battery power
supply voltage. When it detects an abnormal condition (door is unlocked by some way other than using keyless entry
transmitter or door request switch and opened or cut off BCM power supply voltage temporarily), it activates the
warning buzzer (located in BCM), theft deterr ent light, hazard warning relay and horn relay.
The security alarm system has 2 selectable modes.
• A mode: No operation
• B mode: Theft deterrent light blinks, hazard warning lights blink, warning buzzer (located in BCM) sounds and horn
sounds
When B mode is selected and the door is locked using keyl ess entry transmitter or door request switch, the theft
deterrent light (1) flashes at 0.1 second interval for 20 seconds and the se curity alarm system is set to the stand-by
mode (2). Once it is se t to the stand-by mode, the theft deterrent light blinks at 2 second intervals.
When the system is set to stand-by mode and the door is unlocked by some way other than using keyless entry
transmitter or door request switch and opened or cut off BCM power supply voltage temporarily, the alarm devices
operate according to the selected mode as described above.
The alarm stops under either of the following conditions.
• Ignition switch is turned ON
• A certain time has elapsed since the alarm started
For selection of the mode of the security alarm system , refer to “Security Alarm Mode Selection Procedure (If
Equipped)”.

Customer Complaint Analysis
Record details of the problem (failure, complaint) and how it occurred as described by the customer.
For this purpose, use of such a questionnaire form as shown in figure will facilitate collectin g information to the point
required for proper analysis and diagnosis. Customer questionnaire (example)
Problem Symptom Confirmation
Check if what the custom er claimed in “Customer
Questionnaire” is accurately f ound in the vehicle. If that
symptom is found, check whether the symptom is
identified as a failure. (This step should be shared with
the customer if possible.)
DTC Check
Check DTC stored in BCM me mory referring to “DTC
Check”, record it and then clear it referring to “DTC
Clearance”. DTC indicates malfunction that occurred in
the system but does not indicate whether it exists now or
it occurred in the past and the normal condition has been
restored now. To check which case applies, clear DTC
once and check whether or not any fault exists.
Troubleshooting for DTC
Based on the DTC indicated in Step 3 and referring to
applicable DTC flow, locate the cause of the trouble,
namely in a sensor, wire harness, connector, BCM or
other part and repair or replace faulty parts. Body Electrical Control System Symptom Diagnosis
Check the parts or system
suspected as a possible
cause referring to symptom diagnosis of each system.
Check for Intermi ttent Problem
Check parts where an intermit tent trouble is easy to
occur (e.g., wire harness, connector, etc.), referring to
“Intermittent and Poor Connec tion Inspection in Section
00”.
Final Confirmation Test
Confirm that the problem symptom has gone and the
body electrical control system is free from any abnormal
conditions. If what has been repaired is related to the
malfunction DTC, check DTC again and confirm that no
DTC is indicated.

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.
