INSPECTION

1.

Turn ignition switch ON (engine stop) when selector lever is “P” position.

2.

Check that selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
check that selector lever can be shifted from “P” position only when brake pedal is depressed.

3.

Shift the selector lever and check for excessive effort, sticking, noise or rattle.

4.

Check that 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 selector lever matches the position shown by shift position
indicator and manual lever on the transaxle.

5.

The method of operating selector lever to individual positions
correctly should be as shown.

6.

When selector button is pressed in “P”, “R”, “N”, “D” or “L” posi-
tion without applying forward/backward force to selector lever,
check button operation for sticking.

7.

Check that back-up lamps illuminate only when selector lever is
placed in the “R” position.

8.

When in “R” position, check that back-up lamps do not illuminate
even when the selector lever is in the “P” position.

CAUTION:

Check the lighting without pressing shift button.

9.

Check that back-up lamps do not illuminate when selector lever is pushed toward the “R” position when in
the “P” or “N” position.

CAUTION:

Check the lighting without pressing shift button.

10. Check that the engine can only be started with selector lever in the “P” and “N” positions.

11. Check that transaxle is locked completely in “P” position.

ADJUSTMENT

1.

Shift the selector lever to “P” position.

CAUTION:

Turn wheels more than 1/4 rotations and apply the park lock.

2.

Loosen the control cable nut (A).

3.

Place manual lever (B) to “P” position.

CAUTION:

Never apply any force to manual lever.

4.

Tighten the control cable nut. Refer to 

TM-156, "Exploded View"

.

CAUTION:

Description

INFOID:0000000009650123

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
nected with 2 communication lines (CAN-H and CAN-L) allowing a high rate of information transmission with
less wiring. Each control unit transmits/receives data but selectively reads required data only.
