1. NOTICE ABOUT VEHICLE CONDITION WHEN
JACKING UP VEHICLE
(a) The vehicle must be unloaded before jacking up/
lifting up the vehicle. Never jack up/lift up a heavily
loaded vehicle.
(b) When removing heavy parts such as the engine and
transmission, the center of gravity of the vehicle
may shift. To stabilize the vehicle, place a balance
weight in a location where it will not roll or shift, or
use a transmission jack to hold the jacking support.
2. NOTICE FOR USING 4 POST LIFT
(a) Follow the safety procedures outlined in the lift
instruction manual.
(b) Use precautionary measures to prevent the free
wheel beam from damaging tires or wheels.
(c) Use wheel chocks to secure the vehicle.
3. NOTICE FOR USING JACK AND SAFETY STAND
(a) Work on a level surface. Use wheel chocks at all
times.
(b) Set the jack and rigid racks to the specified
locations of the vehicle accurately.
(c) When jacking up the vehicle, first release the
parking brake and move the shift lever to N.
(d) When jacking up the entire vehicle:
(1) When jacking up the front wheels first, make
sure wheel chocks are behind the rear wheels.
(2) When jacking up the rear wheels first, make sure
wheel chocks are in front of the front wheels.
(e) When jacking up only the front or rear wheels of the
vehicle:
(1) Before jacking up the front wheels, place wheel
chocks on both sides of the rear wheels.
(2) Before jacking up the rear wheels, place wheel
chocks on both sides of the front wheels.
(f) When lowering a vehicle that only has its front or
rear wheels jacked up:
(1) Before lowering the front wheels, make sure
wheel chocks are in front of the rear wheels.
(2) Before lowering the rear wheels, make sure
wheel chocks are behind the front wheels.

TS and CG terminal circuit and the ABS warning
light circuit.
(f) Start the engine.
(g) Using SST, perform the speed sensor signal check
in Test Mode.
SST 09843-18040
(h) Drive the vehicle straight forward.
(i) Accelerate the vehicle to a speed of 28 mph (45 km/
h) or higher for several seconds and check that the
ABS warning light goes off.
HINT:
The signal check may not be completed if the
vehicle has its wheels spun.
(j) Stop the vehicle.
NOTICE:
• The speed sensor signal check may not be
completed if the steering wheel is turned or
the wheels are spun during the check.

5. DLC3 (Data Link Connector 3)
(a) The vehicle's ECM uses ISO 15765-4 for
communication protocol. The terminal arrangement
of the DLC3 complies with SAE J1962 and matches
the ISO 15765-4 format.
NOTICE:
*: Before measuring the resistance, leave the
vehicle as is for at least 1 minute and do not
operate the ignition switch, any other switches
or the doors.
HINT:
The DLC3 is the interface prepared for reading
various data from the vehicle's ECM. After
connecting the cable of an intelligent tester, turn the
ignition switch to the ON position and turn the tester
ON.
• If a communication failure message is displayed
on the tester screen (on the tester: UNABLE TO
CONNECT TO VEHICLE), a problem exists in
either the vehicle or tester. In order to identify the
location of the problem, connect the tester to
another vehicle.
• If communication is normal: Inspect the DLC3 on
the original vehicle.
• If communication is impossible: The problem is
probably in the tester itself. Consult the Service
Department listed in the instruction manual.
6. BATTERY VOLTAGE
Battery Voltage:
11 to 14 V
If the voltage is below 11 V, recharge the battery before
proceeding to the next step.
7. MIL (Malfunction Indicator Lamp)
(a) The MIL is illuminated when the ignition switch is
first turned to the ON position (the engine is not
running).

MANUAL SHIFTING TEST
1. PERFORM MANUAL SHIFTING TEST
HINT:
• With this test, it can be determined whether the
trouble occurs in the electrical circuit or is a
mechanical problem in the transaxle.
• If any abnormalities are found in the following test, the
problem is in the transaxle itself.
(a) Disconnect the connector of the transmission wire.
(b) Drive with the transmission wire disconnected.
Shifting the shift lever in the order of L, 2, 3, 4 and D
position to check whether the shifting condition
changes the table below.
HINT:
When driving with the transmission wire
disconnected, the shift lever position is in L or 2, the
gear position is held in 3rd and the shift lever
position is in 3, 4 or D, the gear position is held in
4th. However, when the shift position is in R or P, the
operation is same as usual.
(c) Connect the connector of the transmission wire.
(d) Clear the DTC (See page AX-27).

FAIL-SAFE CHART
1. FAIL-SAFE
This function minimizes the loss of the ECT functions
when any malfunction occurs in a sensor or solenoid.
(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.
(d) Shift solenoid valve SL1, SL2, SL3 and S4:
Fail safe function:
If either of the shift solenoid valve circuits develops
an open or short, the ECM turns the other shift
solenoid "ON" and "OFF" in order to shift into the
gear positions shown in the table below.
Manual shifting as shown in the following table must
be done (In case of a short circuit, the ECM stops
sending the current to the short circuited solenoid).
Even if starting the engine in the fail-safe mode, the
gear position remains in the same position.
