P0963

* The ignition voltage is 10.2-15.5 V.

* The engine speed is greater than 400 RPM for 2 s.

* The transmission is not in emergency mode.

* Driving in D range.

* TCM communication is normal.

* DTC P0962 is not set.

Conditions for Setting the DTC

P0748

Deviation between commanded current and feedback current.

P0961

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

P0962

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

P0963

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.
