Maintenance leaders, according to TACOM maintenance information message (MIM) 23-004, there’s an issue with certain FMTV electronic control modules (ECMs). If your unit has FMTV A1 or A1P2 variants, then be advised the ECMs installed on engines NSN 2815-01-668-9685, NSN 2815-01-668-9679 and NSN 2815-01-668-4779 aren’t programmed.
        
That means if you get one of these new engines or you’re installing a new ECM on it, you’ll need to make sure that you follow the installation procedures to correctly program the ECM. You can find the procedures in the TACOM message HERE.
        
Look for the programming procedures to be added to the next revision of TM 9-2320-333-23P (IETM EM 0372, Jun 19) and TM 9‐2320‐391‐23&P (IETM EM 0369, Oct 17).
        
Also, be sure to return unserviceable engines back to the supply system with the ECM attached to the unserviceable engine.
