2005-2012 Escape Hybrid and 2006-2011 Mariner Hybrid – Malfunction Indicator Lamp (MIL) With DTC P0A7E:00 – Hybrid Battery Pack Over Temperature

Some 2005-2012 Escape and 2006-2011 Mariner Hybrid vehicles can exhibit an illuminated MIL and/or Stop Safely Now message in extreme hot ambient temperatures, with DTC P0A7E:00 present in the Battery Control Module (BCM).

 

Refer to WSM Section 414-03 to diagnose the P0A7E concern.

 

Under extreme hot weather, if diagnosis leads to replacement of the high voltage battery, pull back the carpet covering the battery pack in the back and locate the part number sticker on the battery pack.

 

If the battery part number prefix start with 8M64, 9M68, or AM68, recalibrate the BCM to the latest level using version 94.05 or higher.

 

The calibration raises the overheat threshold to address extreme hot weather operation.

 


 

Service Information & Reprogramming

Software necessary to program electronic modules to the latest calibration level, perform module initialization (PATS), and set Programmable Parameters on Ford, Lincoln and Mercury vehicles.

Ford Module Programming (FMP) is a software application that allows subscribers to program electronic modules on Ford, Lincoln and Mercury vehicles. It can be used for:

  • Reprogramming emission-related (OBDII) modules on some vehicles manufactured in 1995 and all vehicles manufactured from 1996 to the present
  • Reprogramming or reconfiguring non-emission-related modules on many vehicles (UBP and MS-CAN not supported)

In addition, module initialization (PATS) functions such as Keycode Erase/Reprogram and PCM Parameter Reset can be done using this application.
