Default ABS & Active Handling faults code?

Driving along & both warning lights came on. Dealer says EBCM & Brake Press. Modulator failures. GM Parts no longer available.
my ? - What are the odds that both fail at same time, something must be common to both (in my estimation).
My genius fellow Vette owners - got any ideas - like grounding-faults, etc.
Help!

What year? 97-2000 you're up the creek. No parts or rebuilds available, the 2 options are live with it or replace the EBCM with a used unit. If you have an 01 or later the EBCM can be repaired.

EBCM is a common failure. "Brake Press. Modulator" sounds like your dealer did no diagnostics and is just guessing.
It's unlikely that anyone at your dealer has ever worked on a C5. There is no reason a dealer should be your first choice for repair on a 20+ year old vehicle.
Contact your local Corvette club, someone there may have a competent local mechanic.
ABS Fixer may be able to repair your EBCM.

Use the DIC and pull your codes. Since you have an 03 alot of those codes are repairable

Default ABS & Active Handling Failure update

It’s an ‘03 Anniv. With codes as follows:
28-TCS 2 codes
60-IPC 1code
AO-LDCM 8 codes
A1-RDCM 1 code
A6-SCM 1code
we live Way back in the woods & Very Few choices on repair facilities.
On top of this the shift cable broke a mile from home, had to tow it back to dealer. No one around here has side lifts for elevating a C5.
thanks

Well I hope something works out for you, but dealing with a dealership is the 'kiss of death' for your bank account.

Ok, those are the modules that are complaining. We need the actual codes stored in them

sorry team!
the info I posted was reported to me by dealer. I realize now that was totally insufficient! Will use ABS Fixer & get the job done correctly. I have verified all ground terminals in engine bay are good!
