APIM replacement

Recommended Posts

Our 2016 Edge Titanium has been a good reliable vehicle, up to about 24,000 miles when the navigation/GPS took a leave of absence. The dreaded GPS with a strike through it icon appeared on the lower left of the screen. This was accompanied by a noticeable slowdown of all screen functions including the touchpad for channel selection, volume control, temp control, phone, and so on. Online help indicated the APIM module (Accessory Protocol Interface Module) had failed.

 

Bluebonnet Ford in New Braunfels was great to work with and installed a replacement. Even though it took a week to come in, they let us have the car to use in the meantime.

 

Phase II. At exactly 35,900 miles, it went out again. Identical symptoms. Again, Bluebonnet Ford is fixing it under warranty and the replacement has a 12 month 12,000 mile warranty as well. Thats ok, but I'm concerned about the long term reliability of the APIM module as it is serialized to the vehicle and only serviceable by the dealer, plus, its expensive.

 

Does anyone have any other input on what to do when (and I feel like based on history, that it will fail again) it happens again?

There have been bad brand new APIMs so you may have just gotten a bad one. If the new one goes out I would suspect something else or something in the wiring.

You can replace it yourself by programming the replacement APIM with your Edge's original as-built values using a program called Forscan. Frod might say the APIM is "dealer-serviceable only", but it's really not if you know how to use Forscan.

I havent used Forscan but I assume it is fairly intuitive? I am pretty fluent in OBD-II if that helps. Are the OE values defaulted or are they available through Forscan?

You have to buy an OBDII adapter than has a USB connection. $40 or so. Hook that up to a laptop with Forscan installed with an "extended license". You get that from their forums- it's free.

 

Once you are connected, all the modules in the vehicle show up in Forscan. You can go into each module and see what "values" are set for each line of "code".

 

You will need to know what the current APIM has for values- so hook it up before you replace it and see if you can download the valvues (Forscan allows you to save one or all lines/vavlues in a file). If not- I believe you can still get all of the as-built values for your vehicle online from Ford. I know you used to be able to do it dince I downloade them for my truck, but Ford may have pulled that down. Not sure. I think it came form the ETIS site.

 

Anyways, install the new APIM and enter the correct as-built values using Forscan and you should be good to go.

You can get your as-built data directly from Ford. Then you can use forscan to upload that data (.abt file) to your replacement APIM.

And you can use a Bluetooth or USB adapter. Ive used this one many times without any issues;

Heres a recommended USB one:

The best Bluetooth adapter, as far as I know, is the OBDlink MX and connects to both HS & MS CAN in Ford vehicles automatically. Though it is a bit pricier than others.

Correct. That BT is the best (Im agreeing with you, not being smug). However, theres no practical reason for the MS-CAN connectivity as theres not real programming changes one can make in forscan. All the APiM, BCM, ACM, etc changes are on the HS-CAN side of things.

MS-CAN access is good for troubleshooting anything on that bus though. You will be able to datalog it and see it in real time. You might as well get a wired one with a switch. That is the most reliable way (wired) and you have access to everything possible with the switch for both busses.

Don't bring logic into this! :hat_tip:

 

I didn't think about expanding beyond the scope of forscan programming. You're making a lot of sense over there.

APIM maybe going out, again!

On our 016 Edge, the GPS symbol with the strikeout line appeared again yesterday while driving.  The Bluetooth phone function doesnt appear to be connecting, it tries every minute or so then drops.  This is the third time the APIM is failing (or at least, the same symptoms are reappearing).  If it follows prior history, I'll be contacting Ford directly through one back channel I have and hopefully get it resolved.

The last time the GPS failed, it was trying to direct us through a local lake about 20 miles away.  I can imagine what would happen it was an autonomous vehicle under its control!
