Checking of A/T PositionUCS005VL
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 selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm 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 selector lever is in matches the position shown by the
shift position indicator and the transaxle.
5. The method of operating selector lever to individual positions
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 back-up lamps illuminate only when selector lever is
placed in “R” position. Confirm back-up lamps do not illuminate
when selector lever is in “P” or “N” position even if it is pushed
toward “R” position without pressing selector button.
7. Confirm engine can only be started with selector lever in “P” and “N” positions.
8. Make sure A/T is locked completely in “P” position.

A/T SHIFT LOCK SYSTEMPFP:34950
DescriptionUCS005VM

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.
