DTC P2730
- Pressure Control (PC) Solenoid 5 Control Circuit High Voltage
Diagnostic Fault Information
Circuit/System Description
The clutch pressure control solenoid 5 is part of the control solenoid valve assembly and is not serviced separately. The transmission control
module supplies 12 volts to the PC solenoid 5 through the high side driver 1 circuit. The transmission control module controls the clutch pressure
control solenoid 5 through the clutch pressure control solenoid 5 control circuit. The normally low clutch pressure control solenoid 5 flows fluid to
the actuator feed limit valve when commanded ON and exhausts fluid when commanded OFF. The clutch pressure control solenoid 5 regulates the
transmission fluid pressure from the auxiliary transmission fluid pump in order to maintain transmission fluid pressure during electric only and
auto-stop modes.
Conditions for Running the DTC
* 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
P2728
The transmission control module detects an internal electrical performance malfunction of the clutch pressure control solenoid 5 control circuit
when the actual pressure does not equal the commanded pressure for 5 seconds.
P2729
The transmission control module detects an internal low voltage electrical malfunction of the clutch pressure control solenoid 5 control circuit for
500 milliseconds.
P2730
The transmission control module detects an internal high voltage electrical malfunction of the clutch pressure control solenoid 5 control circuit for
500 milliseconds
Action Taken When the DTC Sets
* DTC P2728 is a Type B DTC.
* DTCs P2729 and P2730 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 default
detected.
* The transmission control module commands maximum line pressure.
* The transmission control module freezes transmission adaptive functions.
Conditions for Clearing the DTC
* DTC P2728 is a Type B DTC.
* DTCs P2729 and P2730 are Type A DTCs.
