Possible causes of this fault code include:
- Signal circuit shorted to a voltage source or a shorted sensor.
This fault code will only be present in the exhaust gas treatment monitor unit and will not be present in the engine electronic control module (ECM). The exhaust gas treatment fault code and maintenance lamps will both flash six times in sequence to alert the operator that this condition exists. The engine diagnostic lamps will not illuminate.
