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.
