theroninhunter Posted June 5, 2018 Share Posted June 5, 2018 How easy is it to upgrade the PAM firmware? My local Ford dealer doesn't seem to have a clue and after upgrading to SYNC3 my Park Assist and side sensors no longer work. I've been told I just need the Park Assist Module to be firmware upgraded Quote Link to comment Share on other sites More sharing options...
Phil21185 Posted June 5, 2018 Share Posted June 5, 2018 You need to edit the APIM as built data I think. Have a look at the stickied thread upgrading to sync 2. In the first post there's a document to download with what all the hex addresses refer to. You need to use forscan to edit the correct bit (not byte lol) in the APIM as built section.

theroninhunter Posted June 5, 2018 Author Share Posted June 5, 2018 Hi, My APIM module was configured based on my VIN with Park Assist but he believes the PAM needs a firmware upgrade ontop Quote Link to comment Share on other sites More sharing options...
theroninhunter Posted June 6, 2018 Author Share Posted June 6, 2018 The Park Assist appears to work but the screen images or Visual Aids are jumbled up. If I post the As Built data from the MotorService website and the AsBuilt data from the Sync3 on here can anyone help me highlight the hex values to modify?

theroninhunter Posted June 6, 2018 Author Share Posted June 6, 2018 Cool cheers, I'll post them up tonight. My Elm327 module should arrive today for ForScan Quote Link to comment Share on other sites More sharing options...
Phil21185 Posted June 6, 2018 Share Posted June 6, 2018 You'll need the extended licence for forscan too. Register for free on their forum then apply for the licence through forscan, again for free 🙂 Quote Link to comment Share on other sites More sharing options...
theroninhunter Posted June 6, 2018 Author Share Posted June 6, 2018 OK, so I've got a few DTC errors (See Screenshot1 DTC.png) Here is the APIM data from the Sync3 unit (Screenshot APIM.png) Here is the AsBuilt data from motorService (Screenshot ASBuiltData.png) To my naked eye the values look to be the same for the APIM......

Phil21185 Posted June 6, 2018 Share Posted June 6, 2018 Well if they're the same, that means that the APIM is programmed to the car that your sync 3 came out of and not to the features that you have. I'll have a look-see and post back. In the meantime, make a backup of your current data so we can undo any changes if required. Quote Link to comment Share on other sites More sharing options...
theroninhunter Posted June 6, 2018 Author Share Posted June 6, 2018 So made a bit of progress, I remember a while back that Ford had added the Active Park Assist after they added the VIN onto their database (Demo Car), so I have 12 Parking Sensors which I think makes my Car Perpendicular Park, Parallel Park for Active Parking. So I read online that for 12 Active Park sensors 7D0--04-02 value should be 0007. Enable Correct Park Assist Mode On APIM 7D0-04-02 xxxX xx - Change value to a 7 (w/ All 12 Active Park Assist sensors wired) - Parallel, Perpendicular, Park Out Assist - Change value to a 8 (w/ 10 (or Less) Active Park Assist sensors wired) - Parallel Only - Change value to a 9 (w/ 10 Active Park Assist sensors wired) - Parallel and Park Out Assist Voila Active Park visual screens are now in the correct order, side sensors appear on the FLANK guard, I've not managed to test Active Park properly yet but hope to do so soon.

Ah I meant the AsBuiltData screenshot was using my car's VIN not the Sync 3's original car. BUT originally my car didn't have Active Park Assist so I think the 0005 for 7D0-04-02 was to activate only the Front and Rear Sensors only. Ford installed APA lateron to use as a Demo Car but must have not updated the AsBuilt Data from MotorService. Stupidly I didn't get the AsBuilt data from the Sync 2 before I removed it.

theroninhunter Posted June 6, 2018 Author Share Posted June 6, 2018 What I do not know is how important those other DTC error codes are Quote Link to comment Share on other sites More sharing options...
Phil21185 Posted June 6, 2018 Share Posted June 6, 2018 Depends on what they refer to. Have you come from sync 1 or sync 2? I'm guessing sync 2. The one referring to the gps circuit could be because sync 3 uses a different gps module than sync 2. Do you have nav and is it working?

theroninhunter Posted June 6, 2018 Author Share Posted June 6, 2018 I came from Sync 2, Nav is working. Would the old GPS antenna be wired into the car and the old APIM? As I didn't pull the old antenna out completely Quote Link to comment Share on other sites More sharing options...
Phil21185 Posted June 6, 2018 Share Posted June 6, 2018 Hmm not that then. It could just be a load of codes from the old system being disconnected. Try clearing them with forscan then seeing if they come back after reading them again. Quote Link to comment Share on other sites More sharing options...

Phil21185 Posted June 6, 2018 Share Posted June 6, 2018 On the dtc screen, click the button to read the codes at the bottom, then choose APIM from the drop down menu and then click the reset codes button. Yeah no worries. If there's any come back, post them and their descriptions here and we'll see what we can do! Quote Link to comment Share on other sites More sharing options...
