APIM DTC U0423 - Invalid Data Received

[Zathrus]

I'm original owner of 2013 CMax SE.

 

I have been using OBDMII dongle monthly to read status of Oil Life Monitor.  I always get the following DTC (even after clearing)

 

===APIM DTC U0423:00-28===
Code: U0423 - Invalid Data Received From IPC (Instrument Panel Control)
 
Status:  
 - Previously Set DTC - Not Present at Time of Request
 - Malfunction Indicator Lamp is Off for this DTC
 
Module: Accessory Protocol Interface Module

==========================

 

I am not having any issues (at least that I notice) with the Instrument Panel or my base model radio and small 3 inch display (i.e. No Nav/Touch screen).

 

1. Does anyone have any ideas what this DTC is indicating?
2. Is it perhaps just logging a momentary communication issue (with CAN bus)?
3. Is this something I should have looked into?

 

I have an extended premium warranty plan that expires this fall, so if this DTC is indicating a potential APIM/IPC failure, I will have Ford look into it.

Or, does this fall under the "if it ain't broke, don't fix it" motto ?

 

Thanks.

SM isn’t any help as all it says is to check for and fix any other DTCs in APIM.  Since the APIM (aka SYNC module) is rather expensive to replace, I’d have the dealer look at it to document issue. If the APIM should fail shortly after warranty, you have a case that it was problematic prior to expiry of warranty.

Thanks +3.  Good suggestion. I'll schedule dealer appointment and update this post with findings afterwards.
