* TCM communication is normal.



* DTC P2763 is not set.



Conditions for Setting the DTC



P2759



Deviation between commanded current and feedback current



P2762



The TCM detects the error current more than 80 mA for 2.75 ms.



P2763



The TCM detects at least 5 times less than 23 mA current consumption of the SLU control circuit for 100 ms.



P2764



The TCM detects at least 5 times more than 1.333 A current consumption of the SLU control circuit for 100 ms.



Action Taken When the DTC Sets



P2759, P2762



* DTCs P2759 and P2762 are Type B DTCs.



* The TCM turns OFF all solenoids.



* The TCM allows the vehicle to operate only in second gear and "R" range after a stop.



P2763, P2764



* DTCs P2763 and P2764 are Type B DTCs.



* No self learning function.



* The TCM turns OFF all solenoids.



* The TCM allows the vehicle to operate only in second gear and "R" range after a stop.



Conditions for Clearing the DTC



P2759, P2762



* DTCs P2759 and P2762 are Type B DTCs.



* The TCM detects the error current less than 50 mA for 2.75 ms.



P2763, P2764



* DTCs P2763 and P2764 are Type B DTCs.



* The current consumption of the SLU control circuit is 0.1-1.1 A for 500 ms.



Diagnostic Aids



When attempting to set solenoid electrical DTCs, ensure the TCM is warmed up and the transmission is operated in 2nd gear long enough to ensure



a 3掳C (5掳F) increase in TCM substrate temperature. This will place the TCM in the optimal condition to test solenoid electrical DTCs.
