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

*: If these input/output signals show errors, TCM activates the fail-safe function.

CVT CONTROL SYSTEM : Fail-safe

INFOID:0000000010661335

TCM has a fail-safe mode. The mode functions so that operation can be continued even if the signal circuit of
the main electronically controlled input/output parts is damaged.
If the vehicle shows following behaviors including “poor acceleration”, a malfunction of the applicable system
is detected by TCM and the vehicle may be in a fail-safe mode. At this time, check the DTC code and perform
inspection and repair according to the malfunction diagnosis procedures.
