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.
