Final Inspection for Maintenance ServiceS7RS0B0206034
WARNING!
When carrying out road tests, select a safe
place where no man or no running vehicle is
seen so as to prevent any accident.
Seats
Check that seat slides smoot hly and locks securely at
any position. Also check that reclining mechanism of
front seat back allows it to be locked at any angle.
Seat Belt
Inspect belt system including webbing, buckles, latch
plates, retractors and anchors for damage or wear.
Check that seat belt is securely locked. If “REPLACE
BELT” label on seat belt is visible, replace belt.
Battery Electrolyte Level Check
Check that the electrolyte le vel of all battery cells is
between the upper and lower level lines on the case. If
battery is equipped with built-in indicator, check battery
condition by the indicator. Accelerator Pedal Operation
Check that pedal operates
smoothly without getting
caught or interfered by any other part.
Engine Start
Check engine start for readiness.
WARNING!
Before performing th e following check, be
sure to have enough room around the
vehicle. Then, firmly apply both the parking
brake and the regular brakes. Do not use the
accelerator pedal. If the engine starts, be
ready to turn off the ignition promptly. Take
these precautions because the vehicle could
move without warning and possibly cause
personal injury or property damage.
On automatic transaxle vehicles, try to start the engine in
each select lever position. The starting motor should
crank only in “P” (Park) or “N” (Neutral).
On manual transaxle vehicles, place the shift lever in
“Neutral,” depress clutch pedal fully and try to start.
On Automated Manual Transaxl e vehicles, try to start
the engine in each select le ver position. The starting
motor should crank only when select lever is in “N”
(Neutral) and brake pedal is depressed.
Exhaust System Check
Check for leakage, cracks or loose supports.
Clutch (for Manual Transaxle)
Check for the following.
• Clutch is completely released when depressing clutch pedal,
• No slipping clutch occurs when releasing pedal and accelerating.
• Clutch itself is free fr om any abnormal condition.
Gearshift or Select Lever (Transaxle)
Check gear shift or select lever for smooth shifting to all
positions and for good performance of transaxle in any
position.
With automatic transaxle or Automated Manual
Transaxle equipped vehicle, also check that shift
indicator indicates properly according to which position
select lever is shifted to.
With automatic transaxle equipped vehicle, make sure
that vehicle is at complete stop when shifting select lever
to “P” range position and release all brakes.

DTC CheckS7RS0B1104003
NOTE
• There are two types of OBD system depending on the vehicle specification.
For details, refer to “Precaution on On-
Board Diagnostic (OBD) System”.
• The MIL is turned on when the ECM and/or TCM detect malfunction(s). Each ECM and
TCM stores diagnostic information as the
diagnostic trouble code (DTC) in its
memory and outputs th e DTC to the scan
tool.
Therefore, check both of the ECM and TCM
for any DTC with the SUZUKI scan tool
because the DTC stored in ECM and TCM
is not read and displayed at a time.
However, each of the ECM and TCM needs
not to be checked with the generic scan
tool because the DTC stored in ECM and
TCM is read and displayed at a time.
Using Scan Tool
1) Prepare OBD generic scan tool or SUZUKI scan tool.
2) With ignition switch turned OFF, connect it to DLC (1) located on underside of instrument panel at
driver’s seat side.
Special tool
(A): SUZUKI scan tool
3) Turn ignition switch ON and confirm that MIL lights.
4) Read DTC, pending DTC and freeze frame data according to instructions displayed on scan tool and
print them or write them down. Refer to scan tool
operator’s manual for further details.
If communication between scan tool and ECM is not
possible, check if scan tool is communicable by
connecting it to ECM in another vehicle. If
communication is possible in this case, scan tool is
in good condition. Then check data link connector
and serial data line (circuit) in the vehicle with which
communication was not possible. If connector and
circuit are OK, check that power supply and ground
circuits of ECM and DLC are in good condition
referring to “ECM Power and Ground Circuit Check”. 5) After completing the check,
turn ignition switch OFF
and disconnect scan tool from data link connector.
Without Using Scan Tool (Hong Kong Model) 1) Turn ignition switch to OFF position.
2) Using service wire, ground diagnosis switch terminal (1) of diagnosis connector (2).
3) Turn ON ignition switch and check DTC displayed on
odometer (3) of combination meter.
When more than 2 DTCs are stored in memory,
blinking for each DTC star ts with the smallest DTC
number in increasing order. Also, DTC is indicated
repeatedly until the ignition switch is turned OFF or
disconnect service wire.
NOTE
When no DTC is detected, display on
odometer of combinatio n meter is “0000”.
4) After completing the check, turn ignition switch to
OFF position and disconnect service wire from
diagnosis connector.
