Driving along and all of a sudden reduced power mode...
I pulled over tried to flash with HPT and it wouldnt connect. I notice my speedo is stuck at 75mph when i first turn the key to the ON position. I have checked all of the fuses when I pull the BCM fuse the guage goes dead and there is power to my HPT module. However i get a code 10-PCM no comm. error from the onboard vette diagnostics. I cant even clear that one.
Bill? ... anyone... please help.
