7B-16 AUTOMATIC TRANSMISSION (4 A/T)
2. DIAGNOSTIC TROUBLE CODE (DTC) CHECK, RECORD AND CLEARANCE
To check DTC, refer to “DTC CHECK” in this section. When a DTC exists, it means existence of a malfunction in
the system represented by that code but whether it still exists (current) or it occurred in the past and has gone
(history) is unknown. To know it, clear this DTC once (Refer to “DTC CLEARANCE” in this section.), perform
test drive and/or “TROUBLE SYMPTOM CONFIRMATION” in this section and then check DTC again as
described in “DTC CHECK”. Attempt to diagnose the trouble based on the DTC recorded in this step only or fail-
ure to clear the DTC in this step may mislead the diagnosis or make diagnosing difficult. Even after checking the
DTC with the SUZUKI scan tool, diagnosis should be performed according to this flow chart to check TCM for
proper self-diagnosis function.
3 and 4. VISUAL INSPECTION
As a preliminary step, perform visual check of the following items that support proper function of the automatic
transmission.
5.TROUBLE SYMPTOM CONFIRMATION
Check if what the customer claimed in “CUSTOMER COMPLAINT ANALYSIS” is actually found in the vehicle
and if that symptom is found, whether it is identified as a failure. (This step should be shared with the customer
if possible.)
When the symptom is not actually found, possibility is :
The symptom occurs under certain conditions.
----- Retry with the vehicle under different conditions.
The trouble occurred only temporarily and normal operation has been restored.
----- Perform “DTC CHECK” and if the diagnostic trouble code is indicated, inspect according to the flow
table for that DTC.
6 and 7. RECHECKING AND RECORD OF DTC
Refer to “DTC CHECK” in this section.INSPECTION ITEM REFERRING SECTION
Engine oil ----- level, leakage Section 0B
Engine coolant ----- level, leakage Section 0B
A/T fluid ----- level, leakage, color Section 0B

10B-46 AIR BAG SYSTEM
ON-VEHICLE SERVICE
SERVICE PRECAUTIONS
SERVICE AND DIAGNOSIS
WARNING/CAUTION labels are attached on each part of air bag system components (SDM, air bag (inflator)
modules and seat belt pretensioners). Be sure to follow the instructions.
Many of service procedures require disconnection of “AIR BAG” fuse and air bag (inflator) module(s) (driver
and passenger) from initiator circuit to avoid an accidental deployment.
Do not apply power to the air bag system unless all components are connected or a diagnostic chart
requests it, as this will set a diagnostic trouble code (DTC).
The “AIR BAG DIAGNOSTIC SYSTEM CHECK” must be the starting point of any air bag diagnostics. The
“AIR BAG DIAGNOSTIC SYSTEM CHECK” will verify proper “AIR BAG” warning lamp operation and will
lead you to the correct table to diagnose any air bag malfunctions. Bypassing these procedures may result
in extended diagnostic time, incorrect diagnosis, and incorrect parts replacements.
Never use air bag component parts from another vehicle.
If the vehicle will be exposed to temperatures over 93°C (200°F) (for example, during a paint baking pro-
cess), remove the air bag system components beforehand to avoid component damage or unintended sys-
tem activation.
When handling the air bag (inflator) modules (driver and passenger), seat belt pretensioners (driver and
passenger) or SDM, be careful not to drop it or apply an impact to it. If an excessive impact was applied
(e.g., SDM is dropped, air bag (inflator) module is dropped from a height of 90 cm (3 ft) or more, seat belt
pretensioner (retractor assembly) is dropped from a height of 30 cm (1 ft) or more), never attempt disassem-
bly or repair but replace it with a new one.
When using electric welding, be sure to disconnect air bag (inflator) module connectors (driver and passen-
ger) and seat belt pretensioner connectors (driver and passenger) respectively.
When applying paint around the air bag system related parts, use care so that the harness or connector will
not be exposed to the paint mist.
Never expose air bag system component parts directly to hot air (drying or baking the vehicle after painting)
or flames. WARNING:
If the air bag system and another vehicle system both need repair, Suzuki recommends that the air
bag system be repaired first, to help avoid unintended air bag system activation.
Do not modify the steering wheel, dashboard or any other on or around air bag system compo-
nents. Modifications can adversely affect air bag system performance and lead to injury.
Failure to follow procedures could result in possible air bag system activation, personal injury or
unneeded air bag system repairs.
WARNING:
When performing service on or around air bag system components or air bag wiring, follow the proce-
dures listed in the following pages to temporarily disable the air bag system.
Failure to follow procedures could result in possible air bag system activation, personal injury or
unneeded air bag system repairs.
