Assistance Please 08 Maxxforce Hybrid 239 module* error code issue

I just had truck serviced for electrical No Start issue and it now starts, runs and drives but issue is:

Constant Alarm
! Engine Light
239 module code??
Red Light “switch” ON for Hybrid

the dealer replaced a relay (before the ECM) to get it running and said he did not have the Maxxforce software for the “239 module*” and that the issue is on the Hybrid side. Said to keep it in diesel to drive. But with the alarm banging and I just don’t think it is smart to not fix the issue!

Cannot find any info in my searches for 239 module code or on this issue, or 08 Maxxforce software for sale (I offered to try to find and purchase for the dealer so he can resolve the issue).

Any assistance on what do to or where to take it in the Dallas Texas area would be appreciated.

Thank you in advance
