* TCC PC Sol. Ctrl. Ckt. High Voltage Test Status

* TCC PC Sol. Ctrl. Ckt. Low Voltage Test Status

瀚慖f any test status parameter displays Fault or Malfunction, replace the control solenoid valve assembly.

Repair Instructions

Note:

* Perform the Service Fast Learn Adapts (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and

Inspection/Programming and Relearning) following all transmission related repairs.

Circuit/System Description

Based on input speed and output speed signals, signals from the engine control module (engine speed and throttle opening) and vehicle speed,

smooth lock-up control and slip is performed through the lock-up control solenoid (SLU). The SLU is linearly turned ON and OFF. The lock-up
