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

.

LIST OF CONTROL ITEMS AND INPUT/OUTPUT

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

CVT CONTROL SYSTEM : Fail-safe

INFOID:0000000010354549

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.
