Torque Converter Clutch Solenoid Operation

The Powertrain Control Module (PCM) operates the Torque Converter Clutch (TCC) solenoid by providing a ground path on circuit K54. Circuit K54 connects to PCM cavity 17, and cavity 3 of the solenoid connector.

Circuit F18 supplies battery voltage to the TCC solenoid. Circuit F18 connects to a bus bar in the fuse block fed by circuit A21. A 15 Amp fuse in the fuse block, cavity 10, protects circuit F18. Circuit F18 connects to cavity 54 of the PCM, and cavity 2 of the solenoid connector.
