DIC flashes 0.0

[alfieferenzo84]

So yeah it flashes 0.0 all the time for mpg, fuel used, oil life, and the other thing i forget, But the door sesnors work as when there open it says that, The low washer fuild works, oh but the performance shift lights up hear and there most of the time it dont and if i turn it off or on it dont change on the dic, One last thing is if i unhook my batt i will have no boost gauge for about a week then once it comes back it dont work but is light up but doesnt go up

I have replaced the bcm, pcm, checked all the wires and everything looks good also replaced the dic itself and still no luck, What could it be? Any thoughts or info would be great thanks

Are you sure the wiring is good? Was it checked point to point against the FSM wiring diagrams? Sounds like you still have a loss of Class 2 serial data or a communications problem between relevant modules.

yeah im sure we got all the wires checked

the online guide says to replace the abs/brake/traction module

what do you think?

Also got a code 1573 serial data loss communicaition

I really don't know so it is hard to say whether it is that module for sure. Was that a PXXXX code? Here what I get for DTC P1573.

P1573 - PCM/EBTCM Serial Data Circuit

It could be the EBTCM (electronic brake and traction control) aka ABS module or a wiring problem between the two - PCM module and EBTCM module. Doesn't mean the module is bad although suspect but each module has a UART chip that provides handshake and communication with other components in the serial data bus so it is a possibility. Good luck and let us know how it turns out.

what you got is the code i have

In the steps for michelle online dio it says to replaced brake trac abs module if wires very from 2-5 volts

So that is my next step

still same thing im lost on this so how do i go about checking wires for the 2nd time? Please any help would be great
