My truck (Volvo VNL 780, D13 engine) has two fault codes, MID 140 PSID 239 and PSID 235. It also will not connect diagnostics to other items on the tractor such as the Climate unit, Vehicle ECU, Light Control Module, Etc. Is this likely to be the instrument cluster itself or the wiring harness? JPro diagnostics only pulled an Airbag ECU connection issue, but seeing as the truck is not able to talk to itself, I believe that isn't the whole problem. If it is the Instrument Cluster or Wiring Harness, how much would a repair cost?

Thank you for waiting

mid 140 sid 239 fmi 12,

is for improper communication with the Volvo link module. More than likely the Volvo link module just needs to be updated. To get rid of the fault temporarily you can shut the battery switch off for a min and turn it back on. Any Volvo dealer can update that module takes about 30-45 minutes.

mid 140 sid 235 fmi 12

Yes, is an instrument cluster, Having the module updated will clear this code.

I hope this helps you.

That would make the vehicle's computer unable to connect with everything else outside of the Engine and Transmission diagnostics?wouldn't JPro be able to tell that?
Technician: Wayne, Journeyman replied 9 months ago

Hi,

Thank you for the response

Yes, to your 1st question

No, it will not communicate until updated with the VOLVO software.
