Code P0969 GMC Description

The pressure control solenoid 3 is part of the control solenoid valve assembly which has no serviceable parts. The normally high-pressure control solenoid 3 regulates and directs the pressure control solenoid 3 oil pressure to the 4-5-6 clutch regulator valve and 4-5-6 clutch boost valve. Increasing pressure control solenoid 3 oil pressure increases oil pressure to the 4-5-6 clutch assembly. The Transmission Control Module (TCM) varies the current to the pressure control solenoid 3 through a low side driver. Decreasing the current to the pressure control solenoid 3 increases pressure control solenoid 3 oil pressure by closing OFF the solenoid exhaust port. Increasing the current to the pressure control solenoid 3 decreases pressure control solenoid 3 oil pressure by opening the solenoid exhaust port. Pressure control solenoid 3 power is supplied by the Transmission Control Module through a high side driver. The high-side driver protects the circuit and components from excessive current flow. If excessive current flow is detected, the high side driver will turn OFF. When the fault is corrected the high-side driver will reset.
The Diagnostic Trouble Code (DTC) will be set when the Transmission Control Module detects an internal electrical malfunction on the pressure control solenoid 3 control circuit where the measured pressure control solenoid 3 current does not equal the commanded clutch pressure control solenoid 3 current for 5 s.
