Open the box with the PTCM/RCB/BCM and look for water in there.
Look also in the passenger rear fender in the trunk for water intrusion.
Several items you bring up suggest the car thinks it's moving when it's not.
But the flashing lights suggest a security module/skreem issue.
I'm left wondering if something is screwing up the CAN bus, like water intrusion on a module somewhere.
This one sounds like one for Rudy....
Yup, you said what I was afraid to write.... some outside element messing with things.
1) Looks like the BCM/PCM/RCM are under the hood pass side with lotsa wires heading into pass side compartment toward the TCM.
2) TCM is under pass side footwell
3) Central Locking Pump/Security System Module is in the trunk pass side under the carpet cover.
4) SKREEM is behind the instrument cluster
Several diagnostic/operation descriptions talk about the CAN buss and twisted pair wiring so this sounds like the puter system communication lines and they go everywhere.
Now the time needed to look at this stuff.........
