Powertrain Control Module: Description: Notes
The Powertrain Control Module (1) is concealed in the engine compartment inside the Control Module Box (2) located next to the Battery (3).
The Powertrain Control Module utilizes integrated circuitry and information carried on the Controller Area Network (CAN) data bus along with many hard wired inputs to monitor many sensor and switch inputs throughout the vehicle. In response to those inputs, the internal circuitry and programming of the Powertrain Control Module allow it to control and integrate many electronic functions and features of the vehicle through both hard wired outputs and the transmission of electronic message outputs to other electronic modules in the vehicle over the CAN data bus.
The Powertrain Control Module for this model is serviced only as a complete unit. A Powertrain Control Module can only be repaired by, or replaced through an authorized electronic warranty repair station. Refer to the latest version of the warranty policies and article for a current listing of authorized electronic repair stations.
