Circuit Description

The powertrain is controlled when 2 -way communication (ordinary condition) exists between the ECM and the TCM.

A Hi/Lo 2 -wire circuit between the ECM and the TCM uses a CAN communications

protocol for 2-way communication.

This code is stored whenever a problem is detected in the communications function.
