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



Action Taken When the DTC Sets



P0748, P0961



* DTC P0961 is a Type B DTC.



* The TCM turns OFF all solenoids.



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



P0962, P0963



* DTCs P0962 and P0963 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



P0748, P0961



* DTC P0963 is a Type B DTC.



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



P0962, P0963



* DTCs P0962 and P0963 are Type B DTCs.



* The current consumption of the SLT 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.

Circuit/System Verification



1. Ensure the transmission fluid temperature is between 50-80掳C (122-176掳F).



2. Operate the vehicle in 2nd gear long enough to ensure at least a 3掳C (5掳F) rise in transmission fluid temperature, then operate the vehicle in



Park for 5 s.



3. Observe the scan tool Line Pressure Control Solenoid Valve Current parameter, the reading should be between 0.1-1.1 A.



瀚慖f the parameter in not within specified range or if the DTC resets, go to Circuit/System Testing.
