SERVICE PROCEDURE
- Connect the Ford Integrated Diagnostic System (IDS) service tool or equivalent Scan Tool and check for DTCs. Is DTC P0420 and/or P0430 present?
- No – this article does not apply. Refer to Powertrain Control/Emission Diagnosis (PC/ED) manual for normal diagnosis.
- Yes – reprogram the powertrain control module (PCM) to the latest calibration using IDS or Ford J2534 release 92.05 or higher. Make sure you are connected to the internet when entering module programming to obtain the latest updates. Calibration files may also be obtained at www.motorcraftservice.com. Proceed to Step 2.
- Replace the affected catalytic converter per the DTC.

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.
J2534 Device using Ford Module Programming (FMP) can Reprogram and Configure most Modules.
