IPC and PCM are Monitored by E-Quizzer
The Independent Plausibility Check (IPC) function in the PCM monitors ETC inputs and outputs and takes the
FMEM action. The IPC and PCM are subject to several potential failure modes. Therefore, if the E-Quizzer
determines that the IPC or PCM function is impaired in any way, it takes appropriate Failure Mode and Effects
Management (FMEM) action.
