The compressor has been replaced as has the pressure switch and under hood fuse box. All fuses and relays are good but the Civic diagnostics manual points to a bad MICU. Problem is this is something that requires an HDS to re-flash the MICU to the ignition keys. I can replace the MICU but from what I understand the car won't start until the re-flash is done. Is my understanding correct or is there a way I can replace the MICU and then get the re-flash done later or is there another alternative. My guess is Honda will charge max for the part plus labor and I am guessing this will cost $500+.
