8. Remove control device assembly.
INSTALLATION
Note the following, and install in the reverse order of removal.

The knurled surface of rib should be upward when installing the
control cable to the control device assembly. And insert the con-
trol cable securely.

After installation is completed, adjust and check CVT position.
Refer to CVT-178, "
Adjustment of CVT Position" and CVT-179,
"Checking of CVT Position" .
Adjustment of CVT PositionBCS001MN
1. Place selector lever in “P” position.
2. Loosen control cable nut and place manual lever in “P” position.
CAUTION:
Turn wheels more than 1/4 rotations and apply the park
lock.
3. Hold the control cable at the end. Push and pull it twice or three
times, and then push it with a load of 9.8N (approximately 1 kg,
2.2 lb). Temporarily tighten the lock nut with the control cable
loose.
4. Connect control cable on manual lever.
CAUTION:
No application of a force to the manual lever.
5. Tighten control cable nut.
CAUTION:
Fix the manual lever when tightening.

Checking of CVT PositionBCS001MO
1. Place selector lever in “P” position, and turn ignition switch ON. (Do not start engine.)
2. Make sure selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
make sure selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm the selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the selector lever is in matches the position shown
by the shift position indicator and the transaxle body.
5. The method of operating the lever to individual positions cor-
rectly should be as shown in the figure.
6. Confirm the back-up lamps illuminate only when lever is placed
in the “R” position. Confirm the back-up lamps do not illuminate
when the selector lever is pushed toward the “R” position side
with the gear position remained in the “P” or “N” position.
7. Confirm the engine can only be started with the selector lever in
the “P” and “N” positions.
8. Make sure transaxle is locked completely in “P” position.
9. When selector lever is set to manual shift gate, make sure man-
ual mode is displayed on combination meter.
Shift selector lever to “+” and “-” sides, and make sure set shift position changes.

CVT SHIFT LOCK SYSTEM

CVT SHIFT LOCK SYSTEMPFP:00000
DescriptionBCS001MP

The electrical key interlock mechanism also operates as a shift lock:
With the ignition switch turned to ON, the selector lever cannot be shifted from “P” (parking) to any other
position unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from “P” to any other position.
The key cannot be removed unless the selector lever is placed in “P”.

The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and slider located inside the key cylinder, respectively.

NOTE:
This emergency lever can be used when battery is off ignition key cannot be removed. In the situation like this,
by operating this lever, ignition key can be removed.

Shift Lock Control Unit Reference ValuesBCS001MT
SHIFT LOCK HARNESS CONNECTOR TERMINALS LAYOUT
SHIFT LOCK CONTROL UNIT INSPECTION TABLE
Shift lock control unit terminal data are reference values, measured between each terminal and ground.
NOTE:
Take care that the pointer of circuit tester swings only momentarily because the output time is so short. If the inspection is done with an
oscilloscope, it should be observed that the power source voltage lasts for 3.5 to 10 ms.

Component InspectionBCS001MU
SHIFT LOCK SOLENOID
Check operation by applying battery voltage to the CVT device har-
ness connector.
CAUTION:
Be sure to apply the voltage of the correct polarity to the
respective terminals. Otherwise, the part may be damaged.
DETENTION SWITCH (FOR KEY)
Check continuity between terminals of the CVT device harness con-
nector.
DETENTION SWITCH (FOR SHIFT)
Check continuity between terminals of the CVT device harness con-
nector.
KEY LOCK SOLENOID

Check operation by applying battery voltage to ignition knob switch,
key switch and key lock solenoid harness connector terminal.
CAUTION:
Be careful not to cause burnout of the harness.
