The FICM on certain Ford and Navistar vehicles is mounted in a location where it's exposed to constant heat and vibration, often causing the internal inverter board to stop working properly. When that happens, the only replacement available from the OEM is a complete module assembly, with a housing, controller board and power board, that needs to re-initialized to the vehicle using proprietary programming tools. This Dorman OE FIX fuel injector control module repair directly replaces only the inverter board to reduce the overall repair cost as well as avoid having to program the module, allowing for a DIY repair. This improved component also features an additional securing compound that helps control vibrations and make it less likely to fail the same way again.
