ADJUSTMENT
1. INSPECT SHIFT LEVER POSITION
(a) When shifting the lever from P to the R position with
the ignition switch ON and the brake pedal
depressed, make sure that the shift lever moves
smoothly and moves correctly into position.
(b) Start the engine and make sure that the vehicle
moves forward when shifting the lever from N to the
D position and moves rearward when shifting the
lever to the R position.
If the operation cannot be performed as specified,
inspect the park/neutral position switch assembly
and check the shift lever assembly installation
condition.
2. ADJUST SHIFT LEVER POSITION
(a) Shift the shift lever to the N position.
(b) Slide the adjuster case cover in the direction shown
in the illustration and pull out the lock piece.
(c) Gently pull the cable rod toward the rear of the
vehicle by hand to pull the cable taut.
(d) Press the lock piece into the adjuster case and lock
it.
(e) Slide the cover in the direction shown in the
illustration.
NOTICE:
Slide the cover past the protrusion of the lock
piece.

HYDRAULIC TEST
1. PERFORM HYDRAULIC TEST
(a) Measure the line pressure.
NOTICE:
• Perform the test at the normal operating ATF
temperature: 50 to 80
C (122 to 176F).
• The line pressure test should always be
performed with at least 2 people. One person
should observe the condition of the wheels or
wheel chocks while the other is performing
the test.
• Be careful to prevent SST's hose from
interfering with the exhaust pipe.
• This test must be performed after checking
and adjusting the engine.
• Perform the test with the A/C OFF.
• When conducting the stall test, do not
continue for more than 10 seconds.
(1) Warm up the ATF (Automatic Transmission
Fluid).
(2) Lift the vehicle up.
(3) Remove the engine under cover.
(4) Connect the intelligent tester to the DLC3.
(5) Remove the test plug A on the transaxle case
front left side and install SST.

NOTICE:
There is a difference between the installation
point of the D position and R position.
(6) Start the engine.
(7) Using intelligent tester, shift to D position and
hold 3rd gear by active test, and measure the
line pressure in idling.
Specified line pressure:
(8) Turn the ignition switch off.

wire.
HINT:
Disconnect the connector only when performing
the position stall test.
(10)Start the engine.

INITIALIZATION
1. RESET MEMORY
NOTICE:
• Perform the RESET MEMORY procedures (A/T
initialization) when replacing the automatic
transaxle assembly, engine assembly or ECM.
• RESET MEMORY can be performed only with the
intelligent tester.
HINT:
The ECM memorizes the vehicle conditions when the
ECT controls the automatic transaxle assembly and
engine assembly. Therefore, when the automatic
transaxle assembly, engine assembly, or ECM has been
replaced, it is necessary to reset the memory so that the
ECM can memorize the new information.
The reset procedures are as follows.
(a) Turn the ignition switch OFF.
(b) Connect the intelligent tester to the CAN VIM. Then
connect the CAN VIM to the DLC3.
(c) Turn the ignition switch ON and turn the tester ON.
(d) Enter the following menus: DIAGNOSIS /
ENHANCED OBD II.
(e) Perform the reset memory procedures from the
Engine menu.
CAUTION:
After performing the RESET MEMORY
procedures, be sure to perform the ROAD TEST
(see page AX-13) as described earlier.
HINT:
The ECM learns through the ROAD TEST.

DIAGNOSIS SYSTEM
1. DESCRIPTION
(a) When troubleshooting On-Board Diagnostic (OBD
II) vehicles, the vehicle must be connected to the
OBD II scan tool (complying with SAE J1987).
Various data output from the vehicle's ECM can
then be read.
(b) OBD II regulations require that the vehicle's on-
board computer illuminates the Malfunction
Indicator Lamp (MIL) on the instrument panel when
the computer detects a malfunction in:
(1) The emission control system/components
(2) The powertrain control components (which affect
vehicle emissions)
(3) The computer
In addition, the applicable Diagnostic Trouble
Codes (DTCs) prescribed by SAE J2012 are
recorded in the ECM memory.
When the malfunction does not reoccur, the MIL
stays illuminated until the ignition switch is
turned OFF, and the MIL turns OFF when the
engine is started. However, the DTCs remain
recorded in the ECM memory.
(c) To check DTCs, connect the intelligent tester to the
Data Link Connector 3 (DLC3) of the vehicle. The
tester displays DTCs, the freeze frame data and a
variety of the engine data.
The DTCs and freeze frame data can be erased
with the tester (see page AX-40).
2. NORMAL MODE AND CHECK MODE
(a) The diagnosis system operates in "normal mode"
during normal vehicle use. In normal mode, "2 trip
detection logic" is used to ensure accurate detection
of malfunctions. "Check mode" is also available to
technicians as an option. In check mode, "1 trip
detection logic" is used for simulating malfunction
symptoms and increasing the system's ability to
detect malfunctions, including intermittent
malfunctions.
3. 2 TRIP DETECTION LOGIC
(a) When a malfunction is first detected, the
malfunction is temporarily stored in the ECM
memory (1st trip). If the same malfunction is
detected during the next drive cycle, the MIL is
illuminated (2nd trip).

4. FREEZE FRAME DATA
(a) Freeze frame data records the engine conditions
(fuel system, calculated load, engine coolant
temperature, fuel trim, engine speed, vehicle speed,
etc.) when a malfunction 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
malfunction occurred.
(b) The intelligent tester records freeze frame data in 5
different instances: 1) 3 times before the DTC is set,
2) once when the DTC is set, and 3) once after the
DTC is set. These data can be used to simulate the
vehicle's condition around the time when the
malfunction occurred. The data may help find the
cause of the malfunction, or judge if the DTC is
being caused by a temporary malfunction or not.
5. DATA LINK CONNECTOR 3 (DLC3)
(a) The vehicle's ECM uses the ISO 15765-4 for
communication protocol. The terminal arrangement
of the DLC3 complies with SAE J1962 and matches
the ISO 15765-4 format.
Terminal of DLC3
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.
If the result is not as specified, the DLC3 may have a
malfunction. Repair or replace the harness and connector.
