P2719



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



P2720



The TCM detects at least 5 times less than 23 mA current consumption of the SLC3 control circuit for 100 ms.



P2721



The TCM detects at least 5 times more than 1.333 A current consumption of the SLC3 control circuit for 100 ms.



Action Taken When the DTC Sets



P2716, P2719



* DTCs P2716 and P2719 are Type B DTCs.



* The TCM turns OFF all solenoids.



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



P2720, P2721



* DTCs P2720 and P2721 are Type B DTCs.



* No self learning function



* The TCM turns OFF all solenoids.



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



Conditions for Clearing the DTC



P2716, P2719



* DTCs P2716 and P2719 are Type B DTCs.



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



P2720, P2721



* DTCs P2720 and P2721 are Type B DTCs.



* The current consumption of the SLC3 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 under the optimal conditions to test solenoid electrical DTCs.
