P0962
DTC P0962 is not failed this ignition.
P0963
DTC P0963 is not failed this ignition.
Conditions for Setting the DTC
P0961
The transmission control module detects an internal electrical performance malfunction of the line pressure control solenoid control circuit and the
actual line pressure does not equal the commanded line pressure for 300 milliseconds.
P0962
The transmission control module detects an internal low voltage electrical malfunction of the line pressure control solenoid control circuit for 300
milliseconds.
P0963
The transmission control module detects an internal high voltage electrical malfunction of the line pressure control solenoid control circuit for 300
milliseconds.
Action Taken When the DTC Sets
DTC P0961
* DTC P0961 is a Type B DTC.
* The transmission control module freezes transmission adaptive functions.
DTC P0962
* DTC P0962 is a Type A DTC.
* The transmission control module defaults the transmission to 3rd gear.
* The transmission control module commands maximum line pressure.
* The transmission control module freezes transmission adaptive functions.
DTC P0963
* DTC P0963 is a Type A DTC.
* The transmission control module freezes transmission adaptive functions.
Conditions for Clearing the DTC
* DTC P0961 is a Type B DTC.
* DTCs P0962 and P0963 are Type A DTCs.
Diagnostic Aids
When attempting to set solenoid electrical DTCs, ensure the transmission control module is warmed up and the transmission is operated long
enough to ensure a 3掳C (5掳F) increase in transmission control module temperature. This will place the transmission control module under the
optimal conditions to test solenoid electrical DTCs.
