Circuit Description

Output Driver Modules (ODMs) are used by PCM to turn on many of the current-driven devices that are needed to control various engine and transmission functions. Each ODM is capable of controlling up to 7 separate outputs by applying ground to the device which PCM is commanding on. ODMs have the capability of diagnosing each output circuit individually. DTC will set when an improper voltage level has been detected on output circuit which controls the A/C compressor relay.

A history DTC will clear after 40 consecutive warm-up cycles have occurred without a malfunction. DTC will also clear when battery is disconnected or cleared by scan tool.
