GENERAL INFORMATION 0A-5
CAUTION:

Even when the accident was light enough not to cause air
bags to deploy, be sure to inspect system parts and other
related parts according to instructions under “Repair and
Inspection Required after an Accident” in Section 9J.

When servicing parts other than air bag system, if shocks
may be applied to air bag system component parts, re-
move those parts beforehand.

When handling the air bag (inflator) modules (driver and
passenger) or SDM, be careful not to drop it or apply an im-
pact to it. If an excessive impact was applied (e.g.,
dropped from a height of 91.4 cm (3 feet) or more), never
attempt disassembly or repair but replace it with a new
one.

When grease, cleaning agent, oil, water, etc. has got onto
air bag (inflator) modules (driver and passenger), wipe off
immediately with a dry cloth.

Air bag wire harness can be identified easily as it is cov-
ered with a yellow protection tube. Be very careful when
handling it.

When an open in air bag wire harness, damaged wire har-
ness, connector or terminal is found, replace wire har-
ness, connectors and terminals as an assembly.

Do not apply power to the air bag system unless all com-
ponents are connected or a diagnostic chart requests it,
as this will set a diagnostic trouble code.

Never use air bag system component parts from another
vehicle.

When using electric welding, be sure to temporarily dis-
able air bag system referring to “Disabling Air Bag Sys-
tem” under “Service Precaution” in Section 9J.

Never expose air bag system component parts directly to
hot air (drying or baking the vehicle after painting) or
flames.

WARNING / CAUTION labels are attached on each part of
air bag system components. Be sure to follow the instruc-
tions.

After vehicle is completely repaired, perform “Air Bag
Diagnostic System Check” described in “Diagnosis” in
Section 9J.

1. Check contact tension by inserting and removing just once
2. Check each terminal for bend and proper alignment
GENERAL INFORMATION 0A-15
INTERMITTENT AND POOR CONNECTION
Most intermittent are caused by faulty electrical connections or wir-
ing, although a sticking relay or solenoid can occasionally be at
fault. When checking it for proper connection, perform careful
check of suspect circuits for:

Poor mating of connector halves, or terminals not fully seated in
the connector body (backed out).

Dirt or corrosion on the terminals. The terminals must be clean
and free of any foreign material which could impede proper termi-
nal contact. However, cleaning the terminal with a sand paper or
the like is prohibited.

Damaged connector body, exposing the terminals to moisture
and dirt, as well as not maintaining proper terminal orientation
with the component or mating connector.

Improperly formed or damaged terminals.
Check each connector terminal in problem circuits carefully to en-
sure good contact tension by using the corresponding mating ter-
minal.
If contact tension is not enough, reform it to increase contact ten-
sion or replace.

Poor terminal-to-wire connection.
Check each wire harness in problem circuits for poor connection
by shaking it by hand lightly. If any abnormal condition is found,
repair or replace.

Wire insulation which is rubbed through, causing an intermittent
short as the bare area touches other wiring or parts of the vehicle.

Wiring broken inside the insulation. This condition could cause
continuity check to show a good circuit, but if only 1 or 2 strands
of a multi-strand-type wire are intact, resistance could be far too
high.
If any abnormality is found, repair or replace.

ENGINE GENERAL INFORMATION AND DIAGNOSIS (TBI FOR G10) 6-7
Warm-up Cycle
A warm-up cycle means sufficient vehicle operation such that the
coolant temperature has risen by at least 22C (40F) from engine
starting and reaches a minimum temperature of 70C (160F).
Driving Cycle
A “Driving Cycle” consists of engine startup, driving mode where a
malfunction would be detected if present and engine shutoff.
2 Driving Cycles Detection Logic
The malfunction detected in the first driving cycle is stored in ECM
(PCM) memory (in the form of pending DTC and freeze frame data)
but the malfunction indicator lamp does not light at this time. It lights
up at the second detection of same malfunction also in the next driv-
ing cycle.
Pending DTC
Pending DTC means a DTC detected and stored temporarily at 1
driving cycle of the DTC which is detected in the 2 driving cycles
detection logic.
Freeze Frame Data
ECM (PCM) stores the engine and driving conditions (in the from
of data as shown at the left) at the moment of the detection of a mal-
function in its memory. This data is called “Freeze frame data”.
Therefore, it is possible to know engine and driving conditions (e.g.,
whether the engine was warm or not, where the vehicle was running
or stopped, where air / fuel mixture was lean or rich) when a mal-
function was detected by checking the freeze frame data. Also,
ECM (PCM) has a function to store each freeze frame data for three
different malfunctions in the order as the malfunction is detected.
Utilizing this function, it is possible to know the order of malfunctions
that have been detected. Its use is helpful when rechecking or diag-
nosing a trouble.
Priority of freeze frame data:
ECM (PCM) has 4 frames where the freeze frame data can be
stored. The first frame stores the freeze frame data of the malfunc-
tion which was detected first. However, the freeze frame data
stored in this frame is updated according to the priority described
below. (If malfunction as described in the upper square “1” below
is detected while the freeze frame data in the lower square “2” has
been stored, the freeze frame data “2” will be updated by the freeze
frame data “1”.)
PRIORITY
FREEZE FRAME DATA IN FRAME 1
1
Freeze frame data at initial detection of malfunction
among misfire detected (P0300-P0303), fuel
system too lean (P0171) and fuel system too rich
(P0172)
2Freeze frame data when a malfunction other than
those in “1” above is detected

ENGINE GENERAL INFORMATION AND DIAGNOSIS (TBI FOR G10) 6-13
MALFUNCTION INDICATOR LAMP (MIL)
CHECK
1) Turn ON ignition switch (but the engine at stop) and check that
MIL lights.
If MIL does not light up (or MIL dims), go to “Diagnostic Flow
Table A-1” for troubleshooting.
2) Start engine and check that MIL turns OFF.
If MIL remains ON and no DTC is stored in ECM (PCM), go to
“Diagnostic Flow Table A-2” for troubleshooting.
DIAGNOSTIC TROUBLE CODE (DTC) CHECK
1) Prepare SUZUKI scan tool (Tech-1) or generic scan tool.
2) With ignition switch OFF, connect it to data link connector (DLC)
(1) located on underside of instrument panel at driver’s seat side.
Special Tool:
(A): SUZUKI scan tool
(B): Mass storage cartridge
(C): 16 / 14 pin DLC cable
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 it or write it down.
Refer to scan tool operator’s manual for further details.
If communication between scan tool and ECM (PCM) is not pos-
sible, check if scan tool is communicable by connecting it to
ECM (PCM) 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.
5) After completing the check, turn ignition switch off and discon-
nect scan tool from data link connector.
