The powertrain control module (PCM) uses output driver modules (ODMs) to control many functions of the engine and the transaxle. The ODMs supply the ground path for a PCM controlled device when the PCM commands the device ON. Each ODM is able to control several outputs. Unlike the quad driver modules (QDMs) used in earlier model years. The ODMs are able to diagnoses each output circuit. The PCM monitors the ODMs for circuit conditions that are incorrect for the commanded state of the ODM.
