P0969: Solenoid-C performance is an electrical status check in this table
Understand the documented GM P0969 PCS3 circuit monitor and the source discrepancy in its prerequisite-code line.

Documented application
GM 2010 10OBDG10 Hybrid Diagnostics, only the cited controller and monitor. These are historical calibration examples; individual vehicle, engine and hardware applicability is not established.
The code alone does not identify a failed part or establish that a vehicle is safe to drive. Confirm the vehicle, reporting module and applicable service procedure.
P0969 is labeled pressure-control-solenoid C system performance in this GM transmission table. The actual strategy evaluates the PCS3 electrical status for an invalid control-circuit voltage. It should not automatically be interpreted as a measured hydraulic-pressure error.
Read the status criterion behind the title
Failure is based on the hardware input/output circuitry reporting an out-of-range electrical condition for four seconds within a five-second window. That is different from the adjacent low-voltage and high-voltage circuit classifications, which use shorter electrical-fault decisions.
The source also refers to common electrical enable conditions. A pressure command or shift complaint alone does not establish that PCS3's electrical monitor was enabled or that its hardware status failed.
One prerequisite needs confirmation
The P0969 row names P0965 in its “not failed this key on” condition, although P0965 is the neighboring PCS2 performance entry. That may be intentional interaction or a copied reference; this document alone does not resolve it. Do not replace the printed code with a guessed alternative.
Capture the PCS3 command, available electrical status, supply conditions and companion solenoid codes. The table supports tracing an electrical command-response problem but supplies no universal solenoid replacement, connector pinout or hydraulic test point. Those require the matching transmission service information and professional hybrid-system precautions before invasive testing.
Preserve the distinction between electrical feedback and hydraulic response in the record.
