DTC Descriptors

DTC P0969

- Clutch Pressure Control (PC) Solenoid 3 System Performance

DTC P0970

- Clutch Pressure Control (PC) Solenoid 3 Control Circuit Low Voltage

DTC P0971

- Clutch Pressure Control (PC) Solenoid 3 Control Circuit High Voltage

Diagnostic Fault Information

Circuit/System Description

The clutch pressure (PC) solenoid 3 is part of the control solenoid valve assembly, which has no serviceable components. The normally high clutch

PC solenoid 3 regulates and directs the clutch PC solenoid 3 oil pressure to the R1/4-5-6 clutch regulator valve and 4-5-6 clutch boost valve.

Increasing clutch PC solenoid 3 oil pressure increases oil pressure to the low and reverse clutch or the 4-5-6 clutch, depending on the position of

the clutch select valve 2. The TCM varies the current to the PC solenoid 3 through a low side driver. Decreasing the current to the clutch PC

solenoid 3 increases clutch PC solenoid 3 oil pressure by closing OFF the solenoid exhaust port. Increasing the current to the clutch PC solenoid 3,

decreases clutch PC solenoid 3 oil pressure by opening the solenoid exhaust port. Clutch PC solenoid 3 power is supplied by the TCM through a

high side driver (HSD). The HSD protects the circuit and components from excessive current flow. If excessive current flow is detected, the HSD

will turn OFF. When the fault is corrected the HSD will reset.

Conditions for Running the DTC

P0969

* The engine speed is greater than 400 RPM for 5 seconds.

* The ignition voltage is 8.6 volts or greater.

* DTC P0969 has not set this ignition cycle.

P0970

* The engine speed is greater than 400 RPM for 5 seconds.

* The ignition voltage is 8.6 volts or greater.

* DTC P0970 has not set this ignition cycle.

P0971

* The engine speed is greater than 400 RPM for 5 seconds.

* The ignition voltage is 8.6 volts or greater.

* DTC P0971 has not set this ignition cycle.

Conditions for Setting the DTC

P0969

The TCM detects an internal electrical performance malfunction of the clutch PC solenoid 3 control circuit where the measured clutch PC solenoid

3 currents does not equal the commanded clutch PC solenoid 3 current for 5 seconds.
