Welcome to the Forum @openrage! From the 2012 Edge Workshop Manual... The Body Control Module (BCM) uses the battery current sensor to monitor the battery state of charge. The battery current sensor is attached to the battery ground cable. With the ignition in RUN, ACC, or OFF, a Load Shed message is sent over the CAN when the BCM determines that the battery state of charge is below 40%, 45 minutes have elapsed, or 10% of the charge has been drained. This message turns off the audio system to save the remaining battery charge. Under this condition, SYS OFF TO SAVE BATT is displayed on the center stack infotainment display to notify the driver that battery protection actions are active. To clear the Load Shed state, start the vehicle. Often, as you describe, when symptoms develop across several electronic systems, the root cause is low battery voltage, causing electronic modules to not operate properly and causing Diagnostic Trouble Codes (DTCs) to be set in them. Using a Diagnostic Scan Tool to check for DTCs can be useful toward understanding what's affecting your Edge. The stuck climate controls may be the result of a DTC that, when cleared, will restore the climate control function. You mention you have replaced the vehicle's weak battery and that the Load Shed state and messaging persists, which suggests the replacement battery also has a state of charge issue. If your replacement battery is not newly purchased -- or even if it is -- have the battery load-tested to ensure it isn't faulty or failing due to bad internal cells. For the inoperative Instrument Panel Cluster (IPC), check fuse F11 (10 amp) in the BCM... Normal Operation The Instrument Panel Cluster (IPC) receives a hot at all times voltage from the Body Control Module (BCM) fuse 11 (10A). The IPC uses a run/start input messaged from the BCM over the High Speed Controller Area Network (HS-CAN) . Please let us know the outcome of your further efforts. Good luck!

From the 2011 Edge Workshop Manual, with emphasis added... Illuminated Entry The illuminated entry requests the dimmable backlighting, the parking lamps and the courtesy lamps to illuminate when the ignition is off and a door or liftgate is opened, the RKE transmitter UNLOCK button is pressed, or the vehicle is unlocked using the keyless entry keypad. If no doors are open, the illuminated entry requests the lamps off after 25 seconds have elapsed, the ignition switched out of off, the RKE transmitter LOCK button is pressed, or the vehicle is locked using the keyless entry keypad. Illuminated Exit The illuminated exit requests the dimmable backlighting, the parking lamps, and the courtesy lamps to illuminate for 25 seconds after all doors are closed and the ignition is turned off. The illuminated exit deactivates when the ignition transitions out of off, a door or liftgate becomes ajar, or 25 seconds have elapsed. Ambient Lighting The ambient lighting subsystem provides illumination to the center console cupholders, the storage bin, the door map pockets, the door pull handles, the door release handles, and the front and rear footwells for illuminated entry or when the ignition is in run with the parking lamps on. The ambient lighting is controlled using the touch screen display in the center of the instrument panel. When the illuminated entry feature is active, the ambient lighting defaults to a pre-set color and brightness setting. When all the doors are closed and the illuminated entry is no longer active, the ambient lighting returns to the last color and brightness setting that was set by the operator. The touch screen display is used to select one of 7 color combinations or turn the ambient lighting feature on or off. The ambient lighting system retains the last color setting and brightness between uses. For vehicles with memory seats, the ambient lighting color can also be set to correspond to the Driver 1 or Driver 2 settings. Good luck!

@roush9799: Hopefully, your oil-change provider will be as responsive and thorough toward remedying the source as @edjunior's experience demonstrates is possible. The 2014 Edge Workshop Manual offers the following method toward identifying oil leak sources... Engine Oil Leaks NOTE: When diagnosing engine oil leaks, the source of the leak must be positively identified prior to repair. If the vehicle is driven extensively between adding the fluorescent additive and performing the leak test, fan air or wind can spread the leaking oil and make identifying the location of the leak difficult. Prior to carrying out this procedure, clean the cylinder block, cylinder heads, valve covers, oil pan and flywheel with a suitable solvent to remove all traces of oil. Engine Oil Leaks — Fluorescent Oil Additive Method NOTE: If the factory fill engine oil with dye is present, change the engine oil and the oil filter prior to using the Dye-Lite® Oil-Based Fluid Dye (164-TP33200601). Use the UV Long-Wave W/12-foot Cord & Alligator Clips (164-R3748) or Leak Tracker UV-LED Leak Detection Flashlight (164-TP8695) to carry out the following procedure for oil leak diagnosis. Add 29.6 ml (1 oz) of Dye-Lite® Oil-Based Fluid Dye (164-TP33200601) to a minimum of 0.47L (1/2 qt) and a maximum of 0.95L (1 qt) engine oil. Thoroughly premix the oil based fluid dye or it will not have enough time to reach the crankcase, oil galleries and seal surfaces during this particular 15 minute test. The additive must be added through the oil fill. Check the level on the oil level indicator to determine what amount of oil to premix. If it is in the middle of the crosshatch area or below the full mark, use 0.95L (1 qt). If it is at the full mark, use 0.47L (1/2 qt). NOTE: For best results allow the customer to drive the vehicle for a day. Run the engine for 15 minutes. Stop the engine and inspect all seal and gasket areas for leaks using the UV Leak Detector Kit. A fluoresces white area will identify the leak. For extremely small leaks, several hours may be required for the leak to appear. At the end of the test, make sure the oil level is within the upper and lower oil indicator marks. Remove oil as necessary if it registers above the full mark. Leakage Points — Underhood Examine the following areas for oil leakage: Valve cover gaskets Cylinder head gaskets Oil filter adapter Engine front cover Oil filter adapter and filter body Oil level indicator tube connection Engine Oil Pressure (EOP) switch Leakage Points — Under Engine, With Vehicle on Hoist Examine the following areas for oil leakage: Oil pan gaskets Oil pan sealer Engine front cover gasket Crankshaft front seal Crankshaft rear oil seal Oil filter adapter and filter body Leakage Points — With Transmission and Flywheel Removed Examine the following areas for oil leakage: Crankshaft rear oil seal Rear main bearing cap parting line Flexplate mounting bolt holes (with flexplate installed) Pipe plugs at the end of oil passages Oil leaks at crimped seams in sheet metal parts and cracks in cast or stamped parts can be detected when using the dye method.

From the 2024 Nautilus Workshop Manual... Good luck! Trusted Real-Time Operation Network (TRON) - System Operation and Component Description Overview Trusted Real-Time Operation Network (TRON) is a cyber security protocol applied to certain modules connected to the vehicle communication networks. This protocol provides a digital message authentication for data being communicated between modules on the networks, to make sure the data received by a module is the data sent by the sending module and has not been interrupted or tampered with by an outside source. Trusted Real-Time Operation Network (TRON) Trusted Real-Time Operation Network (TRON) secret data authentication security keys are applied to modules with motion control, safety critical and security critical functions. Not all modules on the vehicle will have data authentication security keys applied. The secret authentication security keys provide a digital data handshake between the sending module and the receiving module to confirm the data received has been sent by the expected source. The initial secret authentication security key distribution takes place at the end of the production line, prior to the vehicle release to the dealer. The key update mechanism includes a key management client and key management server modules. The key management client is the GWM and the key management server modules are the modules participating in the TRON function. The GWM generates the keys and distributes them to itself and the server modules, one module at a time sequentially. The keys are processed by the receiving modules and stored in their memory and a backup of the distributed keys is stored in the TCU . After the vehicle's TRON has been successfully configured, the production line end of line tool sends a copy to the Ford backend data systems for storage. If a TRON-capable module is replaced, the module secret authentication security key must be applied to the new module so it functions on the network when installed. When replacing a TRON capable module, run the FDRS Trusted Real-Time Operation Network (TRON) Module Authentication Diagnosis and Repair procedure to distribute a new set of secret authentication security keys to all TRON-capable modules. The GWM and the TRON capable modules can set Diagnostic Trouble Codes (DTCs) if the keys are misaligned between modules, there are communication issues on the vehicle network or a module is not responding. Component Description Gateway Module The GWM acts as the key management client for the Trusted Real-Time Operation Network (TRON) system for creating, monitoring and distributing the secret keys to the participating modules. Telematic Control Unit Module The TCU stores a backup of all Trusted Real-Time Operation Network (TRON) distributed keys.

Per your final comment, the Hybrid Nautilus does, in fact, utilize the High Voltage battery pack to service the 12-volt battery and low-voltage vehicle systems. Excerpts from the 2024 Nautilus Workshop Manual, with relevant Workshop Manual sections attached below as a PDF documents... Good luck! High Voltage Battery The high voltage battery consists of cells packaged into modules which deliver approximately 260 volts DC to the high voltage system. The high-voltage DC electrical power is converted to low voltage DC electrical power through the Direct Current/Direct Current (DC/DC) converter control module. This low-voltage high current DC electrical power is then supplied to the 12-volt batteries through the low voltage battery cables. Direct Current/Direct Current (DC/DC) Converter Control Module The DCDC is an liquid-cooled component that converts high voltage DC power to low-voltage (12-volt) DC power. The converter provides power to the vehicle 12-volt battery and low-voltage electrical systems. The PCM requests the DCDC to enable power conversion through an enable message over HS-CAN . The PCM sends a charging voltage setpoint request over HS-CAN to the DCDC . DCDC Operation The DCDC is responsible for maintaining and charging the 12-volt battery. The DCDC is protected by a 50 amp high voltage low current fuse located in the high-voltage BJB . The DCDC steps the high-voltage down to a low-voltage (between 12.0 and 15.5 volts, depending on vehicle needs), providing power to the vehicle low-voltage battery systems. Depending on the vehicle and environmental conditions, the DCDC is capable of outputting up to 260 amps to the 12-volt battery.

@Bunky: Yes, per the relevant section of 2024 Nautilus Workshop Manual, attached below in full as a PDF document, you are correct... Good luck! Placing your device cursor over underlined acronyms may yield full-words descriptions of the acronyms: Push Button Ignition Switch The push button ignition switch is used to control the ignition mode. Refer to the following table for information about achieving the various ignition modes. Ignition Entry Condition Desired Ignition Mode Action To Take Off ON (engine off) Press the START/STOP button without applying the brake pedal. Off or on START Apply the brake pedal and then press the START/STOP button. On (engine off) OFF Press the START/STOP button. On (engine running) OFF Press the START/STOP button. Ignition Mode LED Indicator The ignition mode LED indicates the ignition mode of the vehicle. The BCM controls the voltage to the ignition mode LED indicator. Refer to the following table. Ignition Mode Ignition Mode LED Indicator Off Off On (engine off) Flashing On (engine running) On OFF The BCM controls the relays providing voltage to the vehicle electrical systems. When the ignition is in the ON mode, a single press and release of the START/STOP button (without applying the brake pedal) changes the ignition to the OFF mode. No programmed key is required to change the ignition to the OFF mode when the vehicle is running. If the vehicle is in motion, a momentary press of the START/STOP button does not shut the vehicle off. If the vehicle is moving at a speed greater than 15 km/h (9 mph), the START/STOP button must be pressed and held for longer than one second (or pressed 3 times within 2 seconds) to turn the ignition off. When the BCM changes the ignition mode to OFF, it communicates the ignition mode to the other modules by sending an ignition status message over the CAN . ON When the ignition is in the ON mode, the BCM activates the run/start relay to provide voltage to the vehicle electrical systems and communicates the ignition mode to the other modules by sending an ignition status message over the CAN . When the vehicle enters ON mode, multiple indicators in the IPC prove out and the IPC displays the gear selection and the vehicle mileage. START The vehicle temporarily enters the START mode if the brake pedal is applied when the START/STOP button is pressed, and a valid programmed key is detected within the vehicle. In addition to activating the run/start relay, the BCM communicates the ignition mode to the other modules by sending an ignition status message over the CAN . After the ignition has completed the vehicle start sequence, the ignition mode returns to ON and the ignition mode LED in the START/STOP button illuminates steadily. The engine can be started from any ignition mode. Steering Wheel and Column Electrical Components - System Operation and Component Description - 2024 Nautilus Workshop Manual.pdf

The Ford Expedition Forum is a community of experienced and helpful Expedition & Navigator owners that you may enjoy -- but a long as you're here: Per the Expedition-Navigator Workshop Manual, with emphasis added, the Audio Control Module (ACM) is a configurable component... Principles of Operation Configurable modules accommodate a variety of vehicle options, eliminating the need for many unique modules for one vehicle line. These modules must be configured when replaced as part of a repair procedure. Configurable modules should not be exchanged between vehicles since the settings are unique to each vehicle. Failure to configure a new module may result in improper operation and/or Diagnostic Trouble Codes (DTCs) setting. As-Built Data As-Built data is a VIN specific module configuration record. During vehicle build, the configuration from all modules is downloaded and stored in the As-Built database. NOTE: It is not necessary to obtain As-Built data unless directed to do so by the scan tool. This data may be accessed from the technician service publication website. As-Built datasets for Ford-Lincoln-Mercury vehicles from 1999 to current model years can be obtained from the Ford Service Info website (link), where the user selects and submits Country and Language, and then enters and submits the vehicle's VIN on the next webpage. As-Built data is presented in text format as well as an electronic .ab-format downloadable file. As-Built data for the ACM is contained in Line 727 entries, which are among configuration data for all other of the vehicle's configurable modules. It's worth noting that 2008 Navigators are not equipped with SYNC -- which was introduced on the 2009 Navigator -- so looking at ACM As-Built configuration values for 2008 versus 2010 Model Years reveals a significant difference because of the 2010 ACM's added interaction with the vehicle's SYNC (APIM) Module. Be aware that your 2008 ACM values may not be the same as this VIN-specific 2008 ACM As-Built example... It's likely that your 2010 ACM has set Diagnostic Trouble Codes (DTCs) after its installation in your 2008 Navigator, due to the 2010 ACM looking for -- and not finding -- the expected SYNC (APIM) Module. If the 2010 ACM is returnable, then you may choose send it back because of it's SYNC-capability which your 2008 Navigator lacks. If you cannot return the 2010 ACM, then it may be worth obtaining the As-Built configuration values for your 2008 ACM, either from the module itself using a Scan Tool or Forscan on a device connected to your Navigator's OBDII data port, or, by downloading your Navigator's As-Built dataset from the Ford Service Info site. Then, reprogram the 2010 ACM Line 727 values which correspond to your 2008 Navigator ACM's Line 727 values using a Scan Tool or a device containing a licensed version of Forscan capable of module programing via your Navigator's OBDII data port. Doing this may or may not enable the 2010 ACM to produce joyful noise in your Navigator. Good luck!
