STRUCTURE AND OPERATION

SHIFT LOCK SYSTEM : System Description

INFOID:0000000010622450

• The shift lock system prevents the select lever from being moved from “P” position to other positions due to

a driver's improper operation and prevents the occurrence of an abrupt start.

• Shift lock can be released when the following conditions are satisfied.
- Ignition switch is ON.
- Brake pedal is depressed. (Stop lamp switch is ON)

SHIFT LOCK OPERATION AT P POSITION

When brake pedal is not depressed (no selector operation allowed)

When the brake pedal is not depressed with the ignition switch ON,
the shift lock solenoid

is OFF (not energized) and the solenoid rod

is extended with spring.

The connecting lock lever

is located at the position shown in the

figure when the solenoid rod is extended. It prevents the movement
of the detent rod

. The selector lever cannot be shifted from the “P”

position for this reason.

When brake pedal is depressed (selector lever operation allowed)

The shift lock solenoid

is turned ON (energized) when the brake

pedal is depressed with the ignition switch ON. The solenoid rod
is compressed with the electromagnetic force. The connecting lock
lever

rotates when the solenoid rod is compressed. Therefore, the

detent rod

can be moved. The selector lever can be shifted to

other positions for this reason.

FORCIBLE RELEASE OF SHIFT LOCK

• When battery voltage decreases or an electrical/mechanical mal-

function occurs in the shift lock system, the selector lever cannot
be operated in “P” position. When shift lock release rod

is

pressed in this state, lock lever

is forcibly rotated, and then it

becomes possible to release shift lock.

• To release the shift lock forcibly and shift the selector lever from “P” position to other positions, follow the

steps below.

1.

Turn ignition switch OFF.

2.

Apply parking brake.

KEY LOCK SYSTEM

KEY LOCK SYSTEM : System Description

INFOID:0000000011009337

KEY LOCK MECHANISM

The key is not set to LOCK when the selector lever is not selected to P position. This prevents the key from
being removed from the key cylinder.

Key lock status

The slider

in the key cylinder

is moved to the left side of the fig-

ure when the selector lever is in any position other than P position.
The rotator

that rotates together with the key

cannot be rotated

for this reason. The key cannot be removed from the key cylinder
because it cannot be turned to LOCK

.

Key unlock status

The slider

in the key cylinder

is moved to the right side of the

figure when the selector lever is in P position and the finger is
removed from the selector button. The rotator

can be rotated for

this reason. The key

can be removed from the key cylinder

because it can be turned to LOCK

.
