DTC P2728

- Pressure Control (PC) Solenoid 5 System Performance

DTC P2729

- Pressure Control (PC) Solenoid 5 Control Circuit Low Voltage

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.

Circuit/System Description

This diagnostic applies to internal microprocessor integrity conditions within the engine control module (ECM) and the throttle actuator control

(TAC) system. This diagnostic also addresses if the ECM is not programmed.

The ECM monitors its ability to read and write to the memory. It also monitors a timing function. The ECM and the TAC processors are used to

monitor the TAC system data. Both processors monitor the other processors data to verify that the indicated APP calculation is correct. The ECM

performs an intrusive test in order to confirm that the APP signals are not shorted together. The ECM accomplishes this by pulling the APP sensor

2 low momentarily and looking for sensor 1 to also be pulled low.
