* The engine run time is greater than 5 seconds.

* The vehicle speed is less than 200 km/h (124 mph) for 5 seconds.

* The system voltage is 11-18 V.

Conditions for Setting the DTC

P0965

The transmission control module detects an internal electrical performance malfunction of the clutch pressure control solenoid control circuit when

the actual hybrid direct, 2-3-4 clutch pressure does not equal the commanded hybrid direct, 2-3-4 clutch pressure for 5 seconds.

P0966

The transmission control module detects an internal low voltage electrical malfunction of the clutch pressure control solenoid control circuit for 500

milliseconds.

P0967

The transmission control module detects an internal high voltage electrical malfunction of the clutch pressure control solenoid control circuit for

500 milliseconds.

Action Taken When the DTC Sets

* DTC P0965 is a Type B DTC.

* DTCs P0966 and P0967 are Type A DTCs.

* The transmission control module defaults the transmission to a limited shift pattern utilizing 2 forward gears and reverse based on the fault

detected.

* The transmission control module commands maximum line pressure.

* The transmission control module freezes transmission adaptive functions.

Conditions for Clearing the DTC

* DTC P0965 is a Type B DTC.

* DTCs P0966 and P0967 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 TCM temperature parameter. This will place the transmission control module under the optimal conditions

to test solenoid electrical DTCs.
