edgemaster Posted June 23, 2018 Report Share Posted June 23, 2018 Hi, Is there any way to find out if my 2009 LTD has a factory installed sub woofer without removing the head unit? Thanks, Ed Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted June 23, 2018 Report Share Posted June 23, 2018 Several ways to go about this, easiest is to tune to an FM station, lean into the cargo bay and stick your ear up to the sub-woofer grill. Hear sound? Yes. No sound? No. 2nd way is, next time your at your dealer, ask the service rep to print out a copy of the window sticker. Will tell you what was installed on your car "as built".

edgemaster Posted June 24, 2018 Author Report Share Posted June 24, 2018 Silly question, where's that sub-woofer grill? As to printing out a copy of the 2009 window sticker, I doubt that my Ford dealership can do that. I don't have much confidence in anything they're doing.

enigma-2 Posted June 24, 2018 Report Share Posted June 24, 2018 Cargo area, passenger side. Look for the molded grill. Dealer can access this information on the Ford network. Usually they are happy to things like this. As for having confidence in a dealer, remember that to be a certified Ford dealer the mechanics and technicians are required to be school certified. Those that work on transmissions are transmission certified. Tires, high school kid (in training). If you are dissatisfied, ask to speak to the owner. It's in his best interest to keep you happy. If you don't have confidence in the service shop, talk to the Service Manager and tell him your concerns. He reports to the owner (President of the dealership) and will usually go overboard to build your confidence in them. People having confidence in their business is critical to their future. We had a local Chevy dealer, Kirk Chevrolet, who was a crook. Service always doped cars to return for future problems. Word got around, it poisoned the community and they had to close. All service reps (not Service Mgr) will try to bump up the bill. It's a big part of their job. Understand this and you have the power to keep them at bay. On a completely unrelated note, as I can't sleep, when I was in tech school before the Marines, I used to work in servicing radios and TVs back in tbe mid 60's. I would fix the TV and the owner would come in and change a different tube or capacitor or resistol so the TV circuit would draw more current and fail again in six months. That was a common practice when people serviced radios and televisions. I had applied to RCA for a tech job. During the walk through, was briefed on the product lines. Several TVs had the same chassis. But the ones with the better wood cabinets would last longer. Three to four years longer. I asked why and was told that while it was the exact same chassis, they changed a single electrolyte capacitor which would weaken the entire chassis and shorten the life in the cheaper sets. Thats just business. Confidence is in knowing HOW the cheat. 1 Quote Link to comment Share on other sites More sharing options...
edgemaster Posted June 24, 2018 Author Report Share Posted June 24, 2018 Found that grille As to your notes, it seems hard to believe but I guess you are right. Businesses try to take people to the cleaners whenever they can. Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted June 24, 2018 Report Share Posted June 24, 2018 So are you getting any sound out of the grill? Quote Link to comment Share on other sites More sharing options...
edgemaster Posted June 24, 2018 Author Report Share Posted June 24, 2018 Yes, I'm getting a sound there but it's more or less white noise. Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted June 24, 2018 Report Share Posted June 24, 2018 I may be wrong, but it's my understanding that you will not hear anything if there no woofer there. You may have the speaker but the amp is bad. Quote Link to comment Share on other sites More sharing options...
edgemaster Posted June 24, 2018 Author Report Share Posted June 24, 2018 Well, there is noise as I said but I will check if there's a speaker. Is it difficult to remove the grill without breaking it? Maybe you're right and the amp is bad. I am in the process of finding a new head unit (that's why I was asking about the sub woofer) but that's not as easy as it sounds.

enigma-2 Posted June 24, 2018 Report Share Posted June 24, 2018 Try running an Audio Control Module self-diagnostic test. Car should should be in the RUN position or running. Audio unit (radio) should be turned on and tuned to any AM station. IF YOU DO NOT HAVE NAVIGATION To enter the diagnostic mode, press and hold preset buttons 3 and 6 for 3 seconds until the speaker walk-around test begins. This starting test will test each speaker, one-at-a time and you are expected to listen to see if each one is operating properly. After this is over, restart the test and BEFORE the speaker test completes, press: Button #1. The ACM will carry out a self-test. At the end of the self-test, the display either indicates SELF PASS or scrolls through any DTCs present. (Note that the self-test may not indicate all DTCs that are present.) Button #2 will display any DTCs that are present. To scroll through the DTCs, press the TUNE UP button. If no DTCs are present, the display reads NO DTCS. Button #3 tests the AM/FM Antenna Signal Strength. (You will see "SIGNAL ###"). The ACM displays the AM/FM antenna signal strength. To run this test, the audio system should be in AM radio tuner mode before entering the ACM self-diagnostic mode. Button #4 displays the Software Levels (as "SOFT LEVELS"). The ACM displays software levels for various components of the audio system. Knowing the software levels may not aid diagnostics. Press the TUNE UP button to scroll through the software levels. Button # 5 is the "Display Test" (shown as "DISPLAY TEST" on the display, then all segments illuminate). All of the ACM segments illuminate. If the vehicle is equipped with an Front Display Interface Module (FDIM), the segments on the FDIM illuminate, rather than the ACM . Button #6 is to retrieve ACM Part Number (shown as "RADIO CONFIG"). The ACM displays the ACM part number, and various configuration levels. Press the TUNE UP button to scroll to the desired function. IF YOU HAVE NAVIGATION As above to run test and before the speaker walk test is complete, press the "End Test" selection. You will see a display full of tests that you can carry out. Press the "On Demand Self Test" on the screen to test the audio system. At the end of the self-test, the display either indicates "Test Passed" or lists any DTCs present. (Note that the self-test may not indicate all DTCs that are present). If DTCs are suspected, retrieve continuous and on-demand DTCs using the a scan tool. By running a test, you can either be assured that everything is OK or what is wrong with your ACM. Here's a description of each test: "On Demand Self Test". The ACM carries out a self-test. At the end of the self-test, the display either indicates "Test Passed" or lists any DTCs present. Note that the self-test may not indicate all DTCs that are present. If DTCs are suspected, retrieve continuous and on-demand DTCs using the scan tool. "View DTCs". The ACM displays any DTCs that are present. If there is more than a full screen of DTCs present, to scroll through the DTCs, press the down arrow on the display. If no DTCs are present, the display reads NO DTCS. Press the "Clear DTCs" selection to clear any DTCs present. "Configuration Status". The display shows the ACM configuration. A "0" indicates the item is configured off, while a "1" indicates the item is configured on. If the ACM appears to be misconfigured, refer to Section 418-01. (Basically this involves reprogramming the Audio Control Module. This is something only your dealer can do. "System Info". The ACM displays system information for various components of the audio system. The following items are most important for servicing the audio system: Nav Radio Part Number — provides the ACM part number ESN1 — provides the satellite radio Electronic Serial Number (ESN) "GPS Info". The current Global Positioning System (GPS) satellite information is shown, along with the current vehicle position. Pressing the "SV Status" selection provides additional information, if present. "Speaker Walk Test". The ACM carries out the speaker walk test. "DVD Mechanism Test". The ACM tests the internal CD/DVD drive mechanism. "Display Test". This test provides for testing of the touchscreen colors and the touchscreen sectors. Pressing any of the colors on the display causes the whole display to change to that color; pressing the display again returns to the Display Test menu. Pressing the "Touchscreen Activation Test" selection enters the touchscreen sector test. Press any area of the screen to test the touchscreen sector; press the "X" at the RH lower corner of the display to return to the Display Test menu. "Hardkey Test". This test provides for testing of the ACM buttons (not the touchscreen). When each button is pressed, the screen displays the button that is active. This test can also be used to isolate a stuck button. "Radio Signal Strength". The ACM displays the AM/FM antenna signal strength. To run this test, the audio system should be in AM radio tuner mode before entering the ACM self-diagnostic mode. "HDD Test". The ACM tests its internal hard drive. "Sensor I/O Status". The ACM displays inputs it is receiving from external sources. These inputs include: Ignition — indicates ON (ignition in ACC or RUN) or OFF Brake — indicates ON (brake applied) or OFF (brake not applied) Illumination — indicates ON or OFF ReverseGear — indicates ON (vehicle in reverse) or OFF (vehicle not in reverse) "Microphone Test". The ACM tests the microphone by supplying a test tone and monitoring the input from the microphone. As this vehicle is not equipped with a microphone, this test does not provide any diagnostic assistance. "SDARS Signal Strength". The ACM displays the satellite radio antenna signal strength. "Mother-in-Law Seat Airbag Shrapnel Test". This causes the passenger airbag to inflate and spray the passenger seat with deadly shrapnel. You can only run this test once before needing to install an new airbag. (I got bored typing and went off in a tangent. Sorry). If you have a non-navigation ACM, you can TEST your SIRIUS radio 1.Turn the ACM on. 2. Operate the audio system in satellite radio mode. 3. Press and hold preset buttons SIRIUS and 2 for 3 seconds. 4. Upon entering the self-test, the audio system produces 2 continuously alternating tones of different pitch, one for the right channel, then one for the left. The test continues by displaying any DTCs currently present. If no DTCs are present, "NO DTCS" is displayed. If there are DTCs present, the ACM auto-scrolls through the list of active DTCs. Historical DTCs can be viewed by pressing the SIRIUS button and preset button #2 (except navigation) or the SOUND button and preset button 1 (navigation) simultaneously while in the active DTC mode. If any DTCs are present, pressing the SIRIUS button and preset button 2 (except navigation) or the SOUND button and preset button 1 (navigation) prompts CLEAR DTCS? on the ACM . To clear historical DTCs, press preset buttons 1, 2, and 3 consecutively within 4 seconds. To exit historical DTCs (with or without clearing DTCs), press the SIRIUS button and preset button 2 (except navigation) or the SOUND button and preset button 1 (navigation) simultaneously. If no historical DTCs are present, pressing the SIRIUS button and preset button 2 (except navigation) or the SOUND button and preset button 1 (navigation) simultaneously while in active DTC mode displays the DLP software version. To exit the satellite audio bezel diagnostic test, press the SIRIUS button and preset button 2 (except navigation) or the SOUND button and preset button 1 (navigation) simultaneously while the DLP software version is displayed, or turn the ACM off. 1 Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted June 24, 2018 Report Share Posted June 24, 2018 I am in the process of finding a new head unit (that's why I was asking about the sub woofer) but that's not as easy as it sounds. You can always have your existing head unit repaired. Cost is $300 (price with Navigation) from these fellows: https://navrepair.com/collections/all/2009-ford-edge Quote Link to comment Share on other sites More sharing options...
edgemaster Posted June 24, 2018 Author Report Share Posted June 24, 2018 Wow, that's quite a response, I'll have to read it several times just to understand it. Does this procedure apply to my head unit at all? It's the factory one with the 6 CD changer. Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted June 24, 2018 Report Share Posted June 24, 2018 Yes. The two different procedures are whether you have the 4" text-only screen or the 7" visual display sreen. Works no matter which CD/DVD you have. Quote Link to comment Share on other sites More sharing options...
edgemaster Posted June 25, 2018 Author Report Share Posted June 25, 2018 OK, didn't know that. I'll go through the procedure and report back. Thanks a bunch, Ed Quote Link to comment Share on other sites More sharing options...
edgemaster Posted June 25, 2018 Author Report Share Posted June 25, 2018 I did the check and, lo and behold, the sub woofer/amp is dead as a door nail. I tried to remove the grille but it seems that I have to take off the entire side panel in the cargo area. Before I spend hundreds of dollars to have the head unit repaired I'd rather buy a new one, which I had planned anyway. I just haven't found the one I'm looking for, there are too many in the marketplace. Again, thanks for all your input. Ed Quote Link to comment Share on other sites More sharing options...
edgemaster Posted June 25, 2018 Author Report Share Posted June 25, 2018 Just wondering: is the sub woofer amp integrated into the head unit or is there a separate amp installed somewhere in the vehicle? Quote Link to comment Share on other sites More sharing options...
akirby Posted June 25, 2018 Report Share Posted June 25, 2018 Pretty sure it's separate. Quote Link to comment Share on other sites More sharing options...
edgemaster Posted June 25, 2018 Author Report Share Posted June 25, 2018 Makes sense. Would it be installed somewhere in the dash or close to the sub woofer location? Quote Link to comment Share on other sites More sharing options...

enigma-2 Posted June 26, 2018 Report Share Posted June 26, 2018 It's on the back of the woofer. Before you do anything else, check fuse #38 in the cabin fuse panel aka the "smart junction box". (It's on the drivers side, down near your left foot). This fuse is dedicated to the subwoofer amp. Quote Link to comment Share on other sites More sharing options...
rwf78155 Posted June 26, 2018 Report Share Posted June 26, 2018 Amp is either close to or connected to the subwoofer Quote Link to comment Share on other sites More sharing options...
