I popped a CEL on our H2 yesterday. Went to read the codes and it pulled DTC U1064. When I went to clear it EFI threw back an error "ERROR $0281" and failed to clear the code.

I am running the May 12th Firmware 2.05.17(0512) and the 2.5.08(0426) FW.

Based on the code, I am not sure if there is something wrong with the wiring or a module or if EFI isn't working properly.

Thoughts?
