KEY INTERLOCK SYSTEM OUTLINE

E5U051409000N01

• The key interlock system, which is composed of the interlock cable and steering lock, prevents the ignition

switch from being removed when the selector lever is in any position other than the P range. (The ignition
switch cannot be turned to the LOCK position.)

End Of Sie

KEY INTERLOCK SYSTEM OPERATION

E5U051409000N02

Positions other than P position (Key interlock is operating)

• When the selector lever is in a position or range

other than P position, the cable end is set at the
key-locked position. When the engine is switched
off and an attempt is made to turn the ignition
switch to the LOCK position, turning of the cam is
restricted by the slider because the cable end
pushes the slider to the cam side, and the ignition
switch cannot be turned to LOCK.

P Position (Key interlock is not operating)

• When the selector lever is in P position, the cable

end is at the key-unlocked position, and because
the slider does not restrict movement of the cam,
the ignition switch can be turned to LOCK.

End Of Sie

SHIFT LOCK SYSTEM OUTLINE

E5U051430000N01

• To make operation smoother and to simplify internal construction, the shift lock system directly determines

movement of the slider block with the slider pin.

• The shift lock unit consists of the interlock cable, interlock cam, and lock unit.

End Of Sie

SHIFT-LOCK SYSTEM OPERATION

E5U051430000N02

The selector lever can be shifted from P position only when the following conditions are satisfied.

• The brake pedal is depressed.

1. When the brake pedal is not depressed, the slider

pin is pressed into the position shown below by
the brake pedal. Thus the slider block is inhibited
from moving in direction A via the cam. In this
condition, the interlock cable and interlock cam
are locked, and the guide pin on the shift lever
does not move out of the position. Thus the select
lever cannot be shifted to other than P position.

2. When the brake pedal is depressed, the slider pin

moves freely in direction B. The slider block also
starts to move freely. The interlock cable and
interlock cam are not locked, thus shifting out of P
position becomes possible.

SELECTOR LEVER OUTLINE

E5U051446102N01

• Operability has been improved due to the short stroke feature of the selector lever.

• Shift position has been optimized by the reduction of space achieved between the frequently utilized N and D

ranges. Due to this optimization of shift position, a quick and sporty shift operation has been achieved while the
sleek shift feeling of an AT is also maintained.

SELECTOR LEVER STRUCTURE

E5U051446102N02

M Range Switch
Outline

• The M range switch detects the selector lever in M

range position and sends a manual mode request
signal to the TCM.

Operation

• The M range switch is an ON/OFF type switch

that turns on when the selector lever is shifted to
the M range. It also remains on during up-shift
and down-shift operations.

Up Switch
Outline

• The up switch detects an up-shift operation in the

M range and sends an up-shift request signal to
the TCM.

Operation

• The up switch is an ON/OFF type switch that

turns on when the selector lever is in the M range
(+) side position.

Down Switch
Outline

• The down switch detects a down-shift operation in

the M range and sends a down-shift request
signal to the TCM.

Operation

• The down switch is an ON/OFF type switch that

turns on when the selector lever is in the M range
(–) side position.

End Of Sie

STEERING SHIFT SWITCH FUNCTION

E5U051446102N03

• When an up-shift or down-shift operation is detected in M range, an up-shift or down-shift request signal is sent

to the TCM.

End Of Sie

STEERING SHIFT SWITCH CONSTRUCTION/OPERATION

E5U051446102N04

Construction

• There is one pair of up and down switches on both the left and right sides of the steering wheel.

• The down switch is built into the audio control and cruise control switches.

Operation
Sending of up/down-shift request signals

• The TCM detects an up/down-shift request signal according to the voltage applied to terminal 2AF.

• When the up or down switch is operated, the resistor built into the down switch changes the voltage applied to

TCM terminal 2AF.

• The TCM controls upshifting or downshifting based on this change in voltage.
