It appears the engines on board the MH377 flight were equipped with 
Rolls Royce Engine Health Management

"A critical aspect of the EHM system is the transfer of data from 
aircraft to ground. Aircraft Communications Addressing and Reporting 
System (ACARS) digital data-link systems are used as the primary method 
of communication. This transmits the Aircraft Condition Monitoring 
System (ACMS ) reports via a VHF radio or satellite link whilst the 
aircraft is in-flight."

"Communications satellites picked up faint electronic pulses from 
Malaysia Airlines flight MH370 after it went missing on Saturday, but 
the signals gave no indication about where the stray jet was heading nor 
its technical condition, a source close to the investigation said on 
Thursday.

The 'pings' equated to an indication that the aircraft's maintenance 
troubleshooting systems were ready to communicate with satellites if 
needed, but no links were opened because Malaysia Airlines and others 
had not subscribed to the full troubleshooting service, the source said."
