Common Diagnostic Steps:

• Check for any additional trouble codes that may be present and address them first.
• Inspect the transmission fluid level and condition. Refill or replace if necessary.
• Examine the wiring and connectors related to the solenoid switch valve for signs of damage, corrosion, or disconnection.
• Test the operation of the solenoid switch valve using a multimeter or scan tool to ensure it is functioning correctly.
• Verify that the torque converter clutch (TCC) solenoid is operating properly by performing an electrical test on its circuit.
• If applicable, update the vehicle’s powertrain control module (PCM) software to the latest version available from the manufacturer.
• If all else fails, consider replacing the solenoid switch valve or related components as needed based on diagnostic findings.
