P0778
Deviation between commanded current and feedback current.
P0965
The TCM detects the error current more than 80 mA for 2.75 ms.
P0966
The TCM detects at least 5 times less than 23 mA current consumption of the SLC1 control circuit for 100 ms.
P0967
The TCM detects at least 5 times more than 1.333 A current consumption of the SLC1 control circuit for 100 ms.
Action Taken When the DTC Sets
P0778, P0965
* DTC P0965 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.
P0966, P0967
* DTCs P0966 and P0967 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
P0778, P0965
* DTC P0967 is a Type B DTC.
* The TCM detects the error current less than 50 mA for 2.75 ms.
P0966, P0967
* DTCs P0966 and P0967 are Type B DTCs.
* The current consumption of the SLC1 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.
