I have a 93 and the service manusl lists the following for the mentioned codes... I see by your sig you have a 92 - not sure if they are the same.

CCM codes
C41 - Loss of ECM Serial Data Communications
C72 - LCD Dimming Output Circuit Open or Shorted to Ground
H41 - Same as above (H = History)
H54 - FEDS Fuel Enable Failure
H72 - Same as above (H = History)

I've seen these alot before. No biggy. There's some quirk in the CCM's (multiple years) where hooking to the CCM sets this off. Clear history codes and go.
