P0977 ACURA MeaningWhen shift solenoid valves A, B, C, D, and E are turned ON, the hydraulic pressure circuit opens. The hydraulic pressure circuit supplies/discharges hydraulic pressure to/from each clutch according to the combination of the ON/OFF status of the shift solenoid valves. The Powertrain Control Module (PCM) commands the driver circuit to turn on the shift solenoid valve. The circuit diagnoses malfunctions such as a circuit short or open, and sends back a return signal during the PCM's command. When the return signal does not match the PCM command, a malfunction is detected by the PCM. When the return signal does not match the PCM command to turn ON the shift solenoid valve, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
