Service Notice or Precautions
FAIL-SAFE
The TCM has an electronic Fail-Safe (limp home mode). This allows the vehicle to be driven even if a major
electrical input/output device circuit is damaged.
Under Fail-Safe, the vehicle always runs in third gear even with a shift lever position of ª1º, ª2º or ªDº. Cus-
tomer may complain of ªsluggish or poor accelerationº.
When the Fail-Safe operation occurs the next time the key is turned to the ªONº position, the SPORT indi-
cator lamp will blink for about 8 seconds. (For diagnosis, refer to AT-1029.)
The blinking of the SPORT indicator lamp for about 8 seconds will appear only once and be cleared. The
customer may resume normal driving conditions by chance.
Always follow the ªWORK FLOWº (Refer to AT-1040).
The SELF-DIAGNOSIS results will be as follows:
The first SELF-DIAGNOSIS will indicate the damage of the vehicle speed sensor or the revolution
sensor.
During the next SELF-DIAGNOSIS performed after checking the sensor, no damages will be indicated.

AT-1096

Description
+The mechanical key interlock mechanism also operates as a
shift lock:
With the key switch turned to ªONº, the selector lever cannot
be shifted from ªPº (parking) to any other position unless the
brake pedal is depressed.
With the key removed, the selector lever cannot be shifted
from ªPº to any other position.
The key cannot be removed unless the selector lever is
placed in ªPº.
+The shift lock and key interlock mechanisms are controlled
by the ON-OFF operation of the shift lock solenoid and by the
operation of the rotator and slider located inside the key
cylinder, respectively.

Diagnostic Procedure
SYMPTOM 1:
+Selector lever cannot be moved from ªPº position with
key in ªONº position and brake pedal applied.
+Selector lever can be moved from ªPº position with key
in ªONº position and brake pedal released.
+Selector lever can be moved from ªPº position when key
is removed from key cylinder.
SYMPTOM 2:
Ignition key cannot be removed when selector lever is set to
ªPº position. It can be removed when selector lever is set to
any position except ªPº.
Check key interlock cable for damage.

Key Interlock Cable
CAUTION:
+Install key interlock cable in such a way that it will not
be damaged by sharp bends, twists or interference with
adjacent parts.
+After installing key interlock cable to control device,
make sure that casing cap and bracket are firmly
secured in their positions. If casing cap can be removed
with an external load of less than 39.2 N (4.0 kg, 8.8 lb),
replace key interlock cable with new one.
REMOVAL
Unlock slider from adjuster holder and remove rod from cable.
