    15S39 LCM Bypass Recall - Documented

    Hey I know a few guys here were asking for any/all details regarding the most recent flavor of the LCM recall - 15S39. For those of you who don't know I am a tech at a Ford dealer.

    I had a beautiful blue Marauder roll in today for the recall to be done and I thought I would take the opportunity to document the process and explain a little as I go.

    Please just use this information for your own knowledge and try not to take it out on your dealership's employees'. This recall does not pay your technician enough time to do this job and I can tell you not many techs want to get under your dash and cut up your wiring. Your advisors and techs are just trying to do their job and you being a Nazi to either is not something that will help your situation.

    So background; the previous recall 14N01 was a customer satisfaction warranty extension. This type of recall is issued when there are widespread failures of a certain part after the factory warranty has ended. Ford is extending the warranty on the specific part only to keep customers happy, these types of recalls are usually not safety related. Ford will pay to repair your vehicle ONLY IF IT HAS FAILED. If your vehicle was serviced under the 14N01 and you had your LCM replaced under the warranty extension your vehicle will not be eligible for the new 15S39 which now replaces the 14N01 which is no longer active. If this is the case consider yourself lucky, most of the LCMs used in the 14N01 had much higher quality relays and should last the remainder of the vehicles life.

    The new recall 15S39 is a safety recall. This type of recall is a result of crashes or other safety related issues that have been documented as a result of the failed part - in this case if your headlights were to fail it would increase your chances of getting in a collision when driving at night. This type of recall, a repair is performed to every vehicle to either correct or prevent the failure, and is performed on every vehicle. Ford found it too costly to replace every LCM in every 03-05 Panther, so they developed this bypass kit to reduce parts costs, even though it more that doubles labor costs associated with installation.

    Anyway, lets get started.
    Open up my box and here is what's inside the 3W7Z-13C788-A LCM bypass module kit:

    The kit comes with a non-serviceable relay "module" with two harness' covered in convolute and with non-insulated butt connectors already installed and includes heat shrink tubing and zip ties. Pretty typical for this sort of repair from Ford.



    The kit's harness have identical colored circuits on both sides, with the exception that one side has only 5 wires and the other 6. The relay module is to be spliced in-line to the connectors going to the LCM, with the 6 circuit side being sliced on the harness side, and the 5 circuit side being spliced towards the connectors of the LCM. The colors match the circuits they are to be spliced too so this should be pretty easy to not screw up.
    To start I have removed the covers under the steering column, the charcoal colored panel directly under the column does not need to be removed, I just did for clarity. I removed the LCM from the vehicle for maximum access - as most of you know that does not require the pedal assembly to be removed, even if that is what the book says.





    The 6 circuits needed span all three LCM connectors, the black connector has 4 of the circuits and the two grey connectors each have one circuit each to be spliced.
    So all three of the pigtails need to be accessed, and I needed to cut open the electrical tap that protects them, up to the main harness, so I can access individual wires to be cut and spliced into the relay kit. Using the proper tool can prevent damage to the wires that a box cutter or scissors could do.





    Each of the circuits to be modified need to have their individual wires isolated and cut, and yes by this point the battery is disconnected and your precious radio presets and clock have been reset - deal with it.

    Now that the wires have been cut, both sides of the wires need to be stripped in preparation to be attached to the butt connectors.

    An experienced tech always remembers to double check and make sure heat shrink is on the wire prior to crimping or soldering. I decided to crimp and heatshrink all the harness side splices first, and do the connector side splices second.



    Next plug the module in and connect the battery for a quick functions test. Everything works properly!



    The directions indicate to tuck the module up by the PCM and route the harness' below the steering shaft along the instrument panel frame and back up to where they are spliced. The module and harness' are retained with the zip ties provided in the kit.

    Install the LCM and install the covers and boom were done.


    All in all not a fun job. For those of you who have spent some time working under a dash it is not too comfortable, not to mention the lack of motion I have when trying to do detailed steps like cutting and stripping and crimping. Luckily this clean rig was free of dust and debris, most rigs this old are dustier that your attic under the dash.


    Overall I think this is a very poor repair, and my recommendation to everyone with a vehicle affected by this recall is to request it not to be performed. If your LCM fails we all know how to fix it, when know who to call and most of us can get the sucker in and out ourselves. As far as I can tell this recall has no expiration and you'll need to let your dealer know at every visit your request the repair not be performed. This repair is probably going to cause a lot more issues down the road as poor splices come apart or a harness chafes or a relay internal to the "module" fails.

    Could you some help ,

    I could use some help on this subject. I apologize, I have a 2003 Grand Marquis LS. For 3 years I struggled with the headlights not working. I received the notice but my VIN was not on the list and they wanted $800 to replace the module. 2 years ago I replaced the relay for the headlights and all working again. I received another recall letter this time it was for my VIN. I have also been struggling with rear tail lights needing me to tap the LCM to work. My overhead lights occasional worked.
    When I got the letter from Ford I thought they where going to replace the module. When the job was done they told me they did a bypass. All of my other issues where still present. I had to tap the LCM to get the rear lights to work.
    2 weeks later I loss my blinkers, instrument dash lighting, The one light that comes on when the door opens stopped working. My panic button that would make the horn go in panic mode stopped. The horm that would beep when I would lock the door with the key fob stopped making the beep at lock. It might easier to say the only lights that work are the headlights (which was not a problem since I replaced the relay) and my break lights.This Wed I am having the Ford dealer confirm everything they did is still good. If they say it is good we talked about places that will repair the LCM. I want to confirm what they did is not faulty work explainng all these new problems like my blinkers stopped working, instrument dashboard lights (no longer light up or allow diming with control) and the fact that tapping the LCM no longer allows the rear lights to come on could be due to an issue with their worked performed. I'm in worse shaped since the bypass.
    If they say their work is good, should I be able to remove the LCM like I did a few years back or will the LCM bypass for the headlights be an issue for me to remove the LCM and do the relay replacments?
    Whats your thoughts on faulty work causing the new problems.
    The new problems happened within 2 weeks of their work.

    Thank you for any info and I apologize for the 2003 Grand Marquis. This This forum was the closet article on the bypass I could fine. I would be happy to speak with anyone offline if it would be more helpful.

    If this was may car, this is what I'd do.

    Remove the bypass and reconnect all the wires that were cut using solder and heat shrink tubing.

    Replace all the relay in the LCM with higher amperage units and replace the headlight relay with a 30 - 40amp unit.

    BTW... I fix LCMs, it's not cheap but it's not an abortion like this bypass.

    I have a 03' GM with a failing LCM. It's the winter car so need reliable headlights. PM me if your still fixing LCMs. Have no Hi/Lo beams unless I smack the dash hard.

    Thank you for the post and detailed description of the work required. Now I know for sure I won't be doing this recall. I'll be fixing the LCM myself if/when the time comes.

    Thanks for the post! Great writeup!

    Why a non-serviceable relay?

    I always thought the first rule when working with car electrics - NO crimp connections, always solder connections.

    I'm glad I don't have to get this done to my Marauder.

I had occasion to work with the Ford reliability engineers and I can tell you that there's absolutely no way they would have let something that could potentially cause the headlights to fail get past the design stage if it were shown to them. This has to be something that the service organization cooked up on their own.

    15S39 LCM Bypass Recall - Documented

    Thanks very much for the write up and the information. I have never received any recall notices on this from Ford.

    All I know is that my original LCM, along with the radio, failed very early on in 2005-06 and was replaced under warranty. I assumed it was replaced with the very same type, but maybe I got lucky and got the LCM from the 14N01 by some miracle. (The radio died the second time 20k miles ago). Again, I didn't hear about a new module before or now.

    If it does fail again I'll follow up here and replace it myself. I have a bunch of other wiring under there for the alarm, underbody lighting, etc., and I just as soon it not be disturbed.

    Thanks again for all the detail.
