1994 G20 OBD-II INITIAL START TROUBLE CODE

APPLIED MODEL:
1994 (P10) G20

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/F 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.
