(g) 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.
(h) The intelligent tester records freeze frame data in
five different instance: 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 temporary malfunction or not.
2. INSPECT THE DLC3
(a) The vehicle's ECM uses ISO 15765-4for
communication. The terminal arrangement of the
DLC3 complies with SAE J1962 and matches the
ISO 15765-4format.
Terminals of DLC3
CAUTION:
*: 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.

ADJUSTMENT
1. INSPECT SHIFT LEVER POSITION
(a) When shifting from P to R position only with ignition
switch ON and brake pedal, make sure that the
shifting lever moves smoothly and can be
moderately operated.
(b) When starting engine, make sure that the vehicle
moves forward when shifting from N to D position
and moves rearward when shifting to R position.
2. ADJUST SHIFT LEVER POSITION
(a) Loosen the nut on the control shaft lever.
(b) Push the control shaft fully downward.
(c) Return the control shaft lever 2 notches to the N
position.
(d) While pushing the control cable end up with the shift
lever in the N position, install it to the control shaft
lever with the nut.
Torque: 13 N*m (132.6 kgf*cm, 9.5 ft.*lbf)
NOTICE:
• If the control cable end is excessively pushed
up, the shift lever can not be adjusted.
• When tightening the nut, confirm that the
control cable is properly stretched.
(e) Start the engine and make sure that the vehicle
moves forward when shifting the lever from the N to
D position and moves rearward when shifting it to
the R position.

INSTALLATION
1. INSTALL TRANSMISSION CONTROL CABLE
ASSEMBLY
(a) Pull in the control cable to the body.
(b) Install the cable end, as shown in the illustration.
(c) When installing the transmission control cable
assembly on the shift lever plate, place the
projection of the shift cable downward to fit in the
groove of the shift lever plate (FIG.2)
Confirm that the spring in the shift cable outer has
moved to the position (FIG.3) shown in the
illustration.
Confirm that the shift cable is installed on the shift
lever plate properly.
NOTICE:
• To prevent torsion of the inner cable, the
projection on the eye end should face rear.
• Push the cable end to the bottom of the pin.
(d) Install the transmission control cable assembly and
2 nuts.
Torque: 12 N*m (122 kgf*cm, 9 ft.*lbf)
