Abstract
A method for monitoring a main control module operative to command first and second motor control processors of a hybrid powertrain system includes signally connecting a programmable logic device to the main control module and the first and second motor control processors, communicating a first seed signal from the programmable logic device to the main control module, and determining an invalid key signal in the main control module in response to the first seed signal. The invalid key signal is communicated to the programmable logic device.
