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. (If malfunction as described in the upper square “1” 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 each malfunction
is detected. These data are not updated.
Shown in the table 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 DTC.
Non-Euro-OBD Model
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 malfunction indicator lamp (MIL) (1).
• Heated oxygen sensor-1
• Heated oxygen sensor-2
• ECT sensor
•TP sensor
• Throttle actuator
• MAF sensor
• IAT sensor
• CMP sensor
• CKP sensor
• Knock sensor
• Wheel speed sensor
• CPU (Central Processing Unit) of ECM
• APP sensor
• Oil control valve (VVT model)
• Barometric pressure sensor
• A/C refrigerant pressure sensor
• ECM backup power supply
• Fuel level sensor
•CANECM and MIL operate as follows.
• MIL 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 MIL in
the combination meter 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), MIL turns OFF.
• When ECM detects a trouble which has occurred in
the above areas, it makes MIL turn ON while the
engine is running to warn the driver of such
occurrence 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 or it is cleared by SUZUKI scan tool
(SUZUKI-SDT) (2).)
For further detail of the checking / clearing procedure,
refer to “DTC Check” or “DTC Clearance”. Priority Freeze frame data in frame 1
