RWRG0069 - Fault Code 64 on Generation 1 Electronic Clutch Actuator (ECA)
Overview
The UltraShift PLUS transmission is equipped with an Electronic Clutch Actuator (ECA) that controls the position of the
clutch assembly. Power and ground to the ECA are OEM-supplied through a 3-Way Connector directly connected to the vehicle batteries. The ECA is connected to the Transmission
Electronic Control Unit (TECU) by an 8-Way Connector that is
part of the transmission harness. The ECA communicates with
the TECU over the High Integrity Link (HIL) to change position,
show faults or include other operation information.
Note: It has been determined that performing an electrical pretest is not needed.
