Network
Diagnostic Trouble Codes (DTCs) (U-codes) are often a result of
intermittent concerns such as damaged wiring or low battery voltage
occurrences. Additionally, vehicle repair procedures, such as module
reprogramming, often set network Diagnostic Trouble Codes (DTCs).
Replacing a module to resolve a network DTC is unlikely to resolve the concern. To prevent repeat network DTC concerns, inspect all network wiring, especially connectors. Test the vehicle battery.

Refer to Wiring Diagrams Cell 55 for schematic and connector information. Normal Operation and Fault Conditions Temperature Door Actuator - Driver Side, REFER to: Climate Control System - Vehicles With: Dual Automatic Temperature Control (DATC) - System Operation and Component Description (412-00 Climate Control System - General Information, Description and Operation). During an actuator calibration cycle, the FCIM drives the temperature door until the door reaches both internal stops in the HVAC case. If the temperature door is temporarily obstructed or binding during a calibration cycle, the FCIM can interpret this as the actual end of travel for the door. When this condition occurs and the FCIM commands the actuator to its end of travel, the airflow may not be the expected temperature. DTC Fault Trigger Conditions

Refer to Wiring Diagrams Cell 55 for schematic and connector information. Normal Operation and Fault Conditions Voltage is supplied to the blower motor relay from the BJB. When the blower motor relay coil receives power from the FCIM, the relay coil is energized and voltage is delivered to the blower motor speed control. Power and ground for the blower motor is provided by the blower motor speed control. The FCIM sends a Pulse Width Modulated (PWM) signal to the blower motor speed control to control the blower speed.

Refer to Wiring Diagrams Cell 55 for schematic and connector information. Normal Operation and Fault Conditions The air discharge sensors supply a varying voltage to the FCIM based on the temperature of the air being discharged from the vent. The module adjusts the system based on the voltage from each sensor. Each air discharge sensor is supplied voltage from the module and all sensors share a common sensor ground. An open, a short to ground, a short to voltage on one or more of these circuits or a failed air discharge sensor causes the FCIM to set one or more Diagnostic Trouble Codes (DTCs).
