Circuit Description

The ignition 1 voltage is supplied to the torque converter clutch pulse width modulated (TCC PWM) solenoid valve. The transmission control module (TCM) controls the ON and OFF time of the TCC PWM solenoid by controlling the ground side of the TCC solenoid valve control circuit. The TCM uses a PWM duty cycle, in order to control application and release of the TCC. When the solenoid is commanded OFF, the TCM senses high voltage. When the solenoid is commanded ON, the TCM senses low voltage.

When the TCM detects a continuous open or short to ground in the TCC Solenoid valve control circuit, then DTC P2764 sets. DTC P2764 is a type B DTC.
