Fuel pressure relief procedure
After making sure that engine is cold, release fuel pressure as fol-
lows.
1) Place transmission gear shift lever in “Neutral” (Shift selector
lever to “P” range for A/T model), set parking brake, and
block drive wheels.
2) Remove relay box cover.
3) Disconnect fuel pump relay (1) from its connector.
4) Remove fuel filler cap to release fuel vapor pressure in fuel
tank and then reinstall it.
5) Start engine and run it till it stops for lack of fuel. Repeat
cranking engine 2-3 times for about 3 seconds each time to
dissipate fuel pressure in lines. Fuel connections are now
safe for servicing.
6) Upon completion of servicing, connect fuel pump relay (1) to
its connector.
Fuel leakage check procedure
After performing any service on fuel system, check to make sure
that there are no fuel leakages as follows.
1) Turn ON ignition switch for 3 seconds (to operate fuel pump)
and then turn it OFF.
Repeat this (ON and OFF) 3 or 4 times and apply fuel pres-
sure to fuel line. (till fuel pressure is felt by hand placed on
fuel feed hose.)
2) In this state, check to see that there are no fuel leakages
from any part of fuel system. CAUTION:
This work must not be done when engine is hot. If done
so, it may cause adverse effect to catalyst.

In the 2nd through the 4th frames, the freeze frame data of each
malfunction is stored in the order as the malfunction is detected.
These data are not updated.
Shown in the table below are examples of how freeze frame data
are stored when two or more malfunctions are detected.
Freeze Frame Data Clearance :
The freeze frame data is cleared at the same time as clearance of
diagnostic trouble code (DTC).
DATA LINK CONNECTOR (DLC)
DLC (1) is in compliance with SAEJ1962 in its installation posi-
tion, the shape of connector and pin assignment.
Serial data line (K line of ISO 9141) (3) is used for SUZUKI scan
tool or generic scan tool to communicate with ECM, TCM, Air Bag
SDM and ABS control module.
SUZUKI serial data line (6) is used for SUZUKI scan tool to com-
municate with immobilizer control module.FRAME

On-Board Diagnostic System (Vehicle without
Immobilizer Indicator Lamp)
ECM diagnosis troubles which may occur in the area including
the following parts when the ignition switch is ON and the engine
is running, and indicates the result by turning on or flashing mal-
function indicator lamp (1).
Heated oxygen sensor (if equipped)
ECT sensor
TP sensor
IAT sensor
MAP sensor
CMP sensor
CKP sensor
Knock sensor
VSS
CPU (Central Processing Unit) of ECM
ECM and malfunction indicator lamp (1) operate as follows.
Malfunction indicator lamp (1) lights when the ignition switch
is turned ON (but the engine at stop) with the diagnosis
switch terminal ungrounded regardless of the condition of
Engine and Emission Control system. This is only to check
the malfunction indicator lamp (1) bulb and its circuit.
If the above areas of Engine and Emission Control system is
free from any trouble after the engine start (while engine is
running), malfunction indicator lamp (1) turns OFF.
When ECM detects a trouble which has occurred in the
above areas, it makes malfunction indicator lamp (1) turn ON
while the engine is running to warn the driver of such occur-
rence of trouble and at the same time it stores the trouble
area in ECM back-up memory. (The memory is kept as it is
even if the trouble was only temporary and disappeared
immediately. And it is not erased unless the power to ECM is
shut off for specified time below.)
ECM also indicates trouble area in memory by means of
flashing of malfunction indicator lamp (1) at the time of
inspection. (i.e. when connecting diagnosis switch terminal
(2) and ground terminal (4) of monitor connector (3) with a
service wire (5) and ignition switch is turned ON.)
NOTE:
When a trouble occurs in the above areas and disap-
pears soon while the diagnosis switch terminal is
ungrounded and the engine is running, malfunction
indicator lamp (1) lights and remains ON as long as the
trouble exists but it turns OFF when the normal condi-
tion is restored.
Time required to erase diagnostic trouble code mem-
ory thoroughly varies depending on ambient tempera-
ture as follows.

Downloaded from www.Manualslib.com manuals search engine 6-12 ENGINE GENERAL INFORMATION AND DIAGNOSIS
1. 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 an inspection form will facilitate collecting information to the point required for proper anal-
ysis and diagnosis.
2. DIAGNOSTIC TROUBLE CODE (DTC) / FREEZE FRAME DATA CHECK, RECORD AND CLEAR-
ANCE
First, check DTC (including pending DTC), referring to “DTC check” section. If DTC is indicated, print it and
freeze frame data or write them down and then clear them by referring to “DTC clearance” section. DTC indi-
cates 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, check the symptom in ques-
tion according to Step 4 and recheck DTC according to Step 5.
Attempt to diagnose a trouble based on DTC in this step only or failure to clear the DTC in this step will lead to
incorrect diagnosis, trouble diagnosis of a normal circuit or difficulty in troubleshooting.
3. AND 4. VISUAL INSPECTION
As a preliminary step, be sure to perform visual check of the items that support proper function of the engine
referring to “Visual Inspection” section.
5. TROUBLE SYMPTOM CONFIRMATION
Based on information obtained in Step 1 Customer complaint analysis and Step 2 DTC / freeze frame data
check, confirm trouble symptoms. Also, reconfirm DTC according to “DTC Confirmation Procedure” described in
each DTC Diagnosis section.
6. AND 7. RECHECKING AND RECORD OF DTC / FREEZE FRAME DATA
Refer to “DTC Check” section for checking procedure.
8. ENGINE BASIC INSPECTION AND ENGINE DIAGNOSIS TABLE
Perform basic engine check according to the “Engine Basic Inspection” first. When the end of the flow table has
been reached, check the parts of the system suspected as a possible cause referring to “Engine Diagnosis
Table” and based on symptoms appearing on the vehicle (symptoms obtained through steps of customer com-
plaint analysis, trouble symptom confirmation and / or basic engine check) and repair or replace faulty parts, if
any.
9. TROUBLESHOOTING FOR DTC (SEE EACH DTC DIAG. FLOW TABLE)
Based on the DTC indicated in Step 5 and referring to the applicable DTC diag. flow table in this section, locate
the cause of the trouble, namely in a sensor, switch, wire harness, connector, actuator, ECM or other part and
repair or replace faulty parts.
10. CHECK FOR INTERMITTENT PROBLEM
Check parts where an intermittent trouble is easy to occur (e.g., wire harness, connector, etc.), referring to
“Intermittent and Poor Connection” in Section 0A and related circuit of DTC recorded in Step 2.
11. FINAL CONFIRMATION TEST
Confirm that the problem symptom has gone and the engine is free from any abnormal conditions. If what has
been repaired is related to the DTC, clear the DTC once, perform DTC confirmation procedure and confirm that
no DTC is indicated.NOTE:
If only Automatic transmission DTCs (P0702-P1717) or Immobilizer DTCs (P1620-P1623) are indicated
in this step, perform trouble diagnosis according to “Diagnosis” in Section 7B or Section 8G.
