My roadster is down now. From the logs: yesterday I received a 104, followed by two 1144 errors.
I've been having random 1144 errors ever since the annual service last summer. Today, driving to
work, it threw the 104, followed by 1144 and then 922. It powered down and I left it for a couple of hours
to cool off. When I picked it up to bring it home, it threw the 104 followed by a 923 and shut down again.
I'll note that the PEM fan was running yesterday but did not come on this morning when the PEM
heated up.
From the VMS messages:
104 TCM: Lost DMC comms
1144 DMC PEM Fan Problem
922 DMC HW: PhaseB OverTemp fault
923 DMC HW: PhaseC OverTerm fault
Any ideas? I don't have much faith in the Utah SC as last summer when it started with the 1144
errors, they said to start with replacing the fan but they would have to order one. I told them they
were available off ebay but they said they would only install Tesla parts. If it wasn't the fan, then
their response was going to be replace the PEM.
