6-8 ENGINE GENERAL INFORMATION AND DIAGNOSIS
FREEZE FRAME DATA
ECM stores the engine and driving conditions (in the from of data
as shown in the figure) 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, whether the vehicle
was running or stopped, whether air/fuel mixture was lean or rich)
when a malfunction was detected by checking the freeze frame
data. Also, ECM 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 diagnosing a trouble.
Priority of freeze frame data :
ECM has 4 frames where the freeze frame data can be stored.
The first frame stores the freeze frame data of the malfunction
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”.)
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.
[A] : An Example of Freeze Frame Data
[B] : 1st, 2nd or 3rd in parentheses here represents which position in the order
the malfunction is detected.
PRIORITY FREEZE FRAME DATA IN FRAME 1
1 Freeze frame data at initial detection of mal-
function among misfire detected (P0300-
P0304), fuel system too lean (P0171) and fuel
system too rich (P0172)
2 Freeze frame data when a malfunction other
than those in “1” above is detected

DATA LINK CONNECTOR (DLC)
ELC (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) is used for SUZUKI scan tool
(Tech-1) to communicate with ECM, TCM, ABS control module
and Air bag SDM.
SUZUKI serial data line is used for SUZUKI scan tool (Tech -1) to
communicate with immobilizer control module.
PRECAUTION IN DIAGNOSING TROUBLE
Do not disconnect couplers from ECM, battery cable from battery, ECM ground wire harness from engine or
main fuse before confirming diagnostic information (DTC, freeze frame data, etc.) stored in ECM memory.
Such disconnection will erase memorized information in ECM memory.
Diagnostic information stored in ECM memory can be cleared as well as checked by using SUZUKI scan
tool (Tech-1) or generic scan tool (Vehicle with immobilizer indicator lamp). Before using scan tool, read its
Operator’s (Instruction) Manual carefully to have good understanding as to what functions are available and
how to use it.
Priorities for diagnosing troubles (Vehicle with immobilizer indicator lamp).
If two or more DTCs are stored, proceed to the flow table of the DTC which has detected earliest in the order
(it can be identified by referring to freeze frame data) and follow the instruction in that table.
If no instructions are given, troubleshoot diagnostic trouble codes according to the following priorities.
–Diagnostic trouble codes (DTCs) other than DTC P0171/P0172 (Fuel system too lean/too rich), DTC
P0300/P0301/P0302/P0303/P0304 (Misfire detected) and DTC P0400 (EGR flow malfunction)
–DTC P0171/P0172 (Fuel system too lean/too rich) and DTC P0400 (EGR flow malfunction)
–DTC P0300/P0301/P0302/P0303/P0304 (Misfire detected)
Be sure to read “Precautions for Electrical Circuit Service” in Section 0A before inspection and observe what
is written there.
