SERVICE INFORMATION
"A/T INITIAL START" may appear when you access the self-diagnostic results in the A/T system using CONSULT.
This message indicates that the self-diagnosis results of self-learning have not been memorized in the automatic transmission control unit.
This message is stored in the self-diagnostic memory of the automatic transmission control unit whenever the following systems are disrupted:
- The battery cable is disconnected
- The power supply line is short circuited
- The connector at the control unit has poor contact
- The fuse in the power supply circuit burns out
- The connector from the control unit is disconnected
- The control unit is replaced
- The battery runs down
- The battery is replaced
SERVICE PROCEDURE
Erase "A/T INITIAL START" from the self-diagnostic results using CONSULT.
Since an actual A/T DTC will over-ride "A/T Initial Start" code, it is not necessary to drive the vehicle after erasing the code. An actual DTC code will replace "A/T Initial start" if there had been an actual incident with the transmission after the power to the transmission control unit was interrupted.
