Trouble Codes $7EA & $8EA.

2006 RX400h
Check engine light came on. Read codes $7EA and $7E8. Anyone know what they mean? I have not seen this code format before. Was able to clear the codes but haven't driven the car since.
Any help appreciated.

Sorry nobody has answered but I am at a loss, never seen those codes read on a reader. Is it possible your reader is bad? Take it to Autozone and have them read it.

found this on Prius site:

Those are typically ECU addresses...... 7EA and 7EB are response addresses HVECU and the Traction Battery

// ECUs
// -- request/response
// -- 7E0/7E8 for ECM (engine control module);
// -- 7E1/7E9 for TCM (transmission control module).
// -- 7E2/7EA for HVECU (Hybrid contol module)
// -- 7E3/7EB for Traction Battery
// -- 7E4/7EC
// -- 7E5/7ED
// -- 7E6/7EE
// -- 7E7/7EF
