DIAGNOSTICS SFI SYSTEM (2AZ−FSE)
AVENSIS Supplement (RM 1045E)
S Freeze frame data:
The freeze frame data records the engine conditions (fuel
system, calculated load, engine coolant temperature, fuel
trim, engine speed, vehicle speed, etc.) when a malfunc-
tion is detected. When troubleshooting, freeze frame data
can help determine if the vehicle was running or stopped,
if the engine was warmed up or not, if the air −fuel ratio
was lean or rich, and other data from the time the malfunc-
tion occurred.
Priorities for troubleshooting:
When multiple DTCs occur, find out the order in which the DTCs
should be inspected by checking the component’s DTC chart.
If no instructions are written in the DTC chart, check DTCs in the
following order of priority:
(a) DTCs ot her t han f uel t r im m alf unct ion DTCs ( P0 1 71 ,
P0 172, P0 174 and P0 175) and misfire DTCs (P0300 to
P0304).
(b) Fuel trim malfunction DTCs (P0 171,P0 172, P0 174 and
P0 175).
(c) Misfire DTCs (P0300 to P0304).
2. DESCRIPTION for M −OBD (Except European spec.)
S When troubleshoot Multiplex OBD (M −OBD) vehicles, the
only difference from the usual troubleshooting procedure
is that you connect the hand −held tester to the vehicle,
and read the various data output from the vehicle’s ECM.
S The vehicle’s on −board computer illuminates the check
engine warning lamp (CHK ENG) on the instrument panel
when the computer detects a malfunction in the computer
itself or in drive system components. In addition, the appli-
cable Diagnostic Trouble Codes (DTCs) are recorded in
the ECM memory (see page 05 −31).
If the malfunction does not recur, the CHK ENG goes off be dis-
appeared by turning the ignition switch to OFF, but the recorded
DTCs remain in the ECM memory.
S To check the DTCs, connect the hand −held tester to the
Data Link Connector 3 (DLC3) on the vehicle or connect
terminals TC and CG on the DLC3(DTCs will be displayd
on the multi −information display).
S The diagnosis system operates in normal mode during
normal vehicle use. In ”normal mode”, 2 trip detection log-
ic* is used to ensure accurate detection of malfunctions.
A ”check mode”, is also available to technicians as an op-
tion. In ”check mode”, 1 trip detection logic is used for sim-
ulating malfunction symptoms and increasing the sys-
tem’s ability to detect malfunctions, including intermittent
malfunctions (hand −held tester only)
(see page 05 −20).

S*2 trip detection logic:
When a malfunction is first detected, the malfunction is
temporarily stored in the ECM memory (1st trip). If the
ignition switch is turned OFF and then ON again, and the
same malfunction is detected again, the CHK ENG will il-
luminate (2nd trip).
SFreeze frame data:
The freeze frame data records the engine conditions (fuel
system, calculated load, engine coolant temperature, fuel
trim, engine speed, vehicle speed, etc.) when a malfunc-
tion is detected. When troubleshooting, freeze frame data
can help determine if the vehicle was running or stopped,
if the engine was warmed up or not, if the air−fuel ratio
was lean or rich, and other data from the time the malfunc-
tion occurred.
Priorities for troubleshooting:
When multiple DTCs occur, find out the order in which the DTCs
should be inspected by checking the component’s DTC chart.
If no instructions are written in the DTC chart, check DTCs in the
following order of priority:
(a) DTCs other than fuel trim malfunction DTCs (P0171,
P0172, P0174 and P0175) and misfire DTCs (P0300 to
P0304).
(b) Fuel trim malfunction DTCs (P0171,P0172, P0174 and
P0175).
(c) Misfire DTCs (P0300 to P0304).
3. CHECK DLC3.
(a) The vehicle’s ECM uses the ISO 9141−2 (Euro−OBD)/
ISO14230(M−OBD) communication protocol. The termi-
nal arrangement of the DLC3 complies with ISO
15031−03 and matches the ISO 9141−2/ ISO14230 for-
mat.

HINT:
Connect the cable of the OBD II scan tool or the hand−held tes-
ter to the DLC3, turn the ignition switch ON and attempt to use
the hand−held tester. If the screen displays UNABLE TO CON-
NECT TO VEHICLE, a problem exists in the vehicle side or the
tester side.
SIf communication is normal when the tool is connected to
another vehicle, inspect the DLC3 on the original vehicle.
