Fail-Safe Remarks

The A/T control unit has an electronic Fail-Safe (limp home mode) to allow the vehicle to be driven even in the event of damage of a major electrical input or output device circuit.

In this condition, the vehicle runs in third gear in positions 1, 2 or D and will not upshift. Customer may say "Sluggish, poor acceleration."

When Fail-Safe operation occurs the next time the key is turned to the ON position, the O.D. OFF indicator lamp will blink for about 8 seconds. (For diagnosis, refer to Self-Diagnostic Procedure (Without Consult)). Self-Diagnostic Procedure (Without CONSULT)

Remarks
- If the vehicle is driven under extreme conditions such as excessive wheel spinning and emergency braking suddenly after, Fail-Safe may be activated even if all electrical circuits are undamaged. In this case, normal shift pattern can be returned by turning the ignition key OFF for 3 seconds and then back ON.

- The blinking of the O.D. OFF 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 "WORK FLOW".
- 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 sensors, no damages will be indicated.
