Checking of CVT PositionUCS0064K
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 that the actual position of the selector lever matches the position shown by the shift
position indicator and the manual lever on the transaxle.
5. The method of operating the selector lever to individual posi-
tions correctly should be as shown.

(A): Press selector button to operate selector lever, while
depressing the brake pedal.

(B): Press selector button to operate selector lever.

(C): Selector lever can be operated without pressing selector
button.
6. Confirm the back-up lamps illuminate only when selector lever is
placed in the “R” position. Confirm the back-up lamps do not illu-
minate 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.

CVT SHIFT LOCK SYSTEMPFP:00000
DescriptionUCS0064L

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

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 key cylinder, respectively.
