FAIL−SAFE CHART
1. FAIL−SAFE
This function minimizes the loss of the ECT functions when any malfunction occurs in each sensor or sole-
noid.
(a) ATF (Automatic Transmission Fluid) temperature sensor:
When the ATF temperature sensor has a malfunction, 5th upshift is prohibited.
(b) Counter gear speed sensor NC (Speed sensor NC):
When the counter gear speed sensor has a malfunction, 5th upshift is prohibited.
(c) Shift solenoid valve DSL:
When the solenoid valve DSL has a malfunction, the current to the solenoid valve is stopped.
This stops lock−up control, then fuel economy decreases.

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.
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 (MIL)) on the instrument
panel when the computer detects a malfunction in the
computer itself or in drive system components. In addi-
tion, the applicable Diagnostic Trouble Codes (DTCs) are
recorded in the ECM memory (see page 05 −564).
If the malfunction does not recur, the CHK ENG (MIL) goes off
be disappeared by turning the ignition switch to OFF, but the re-
corded 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 −558).
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 (MIL)
will illuminate (2nd trip).

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:
If your display shows ”UNABLE TO CONNECT TO VEHICLE”
when you have connected the cable of hand−held tester to the
DLC3, turned the ignition switch to the ON position and oper-
ated the hand−held tester, there is a problem on the vehicle side
or tool side.
SIf communication is normal when the tool is connected to
another vehicle, inspect DLC3 on the original vehicle.
SIf communication is still not possible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool’s instruction manual.
4. INSPECT BATTERY VOLTAGE
(a) Measure the battery voltage.
Battery Voltage:11to14V
If the voltage is below11V, recharge the battery before pro-
ceeding.
