Tiger 1200xrt Fault Codes

C1088: CAN FAULT - lost comms with ABS module or ABS system
C1108: TSAS - ABS implausible signal
Both faults constantly return after being cleared, dealer has contacted Triumph and they apparently haven't seen this before.
Faults found through updates etc during 2 yr service and no warnings on dash. Bike was 26 days out of warranty but still hoping Triumph will look into it.
Your thoughts are appreciated.

 

The bike had a service at my local dealer, clutch and brake fluid renewed.
They contacted me today to say that they'd been on to Triumph and they say it's due to low voltage when the engine cranks which is kidding the ABS system.
Checked the battery today and the static voltage was 12.55v, running voltage is 14.47v1 then checked static voltage 40 mins later and it was 12.63v. Service department thought the static voltage should be 12.7v so need to confirm. Battery was new in August as the original failed after 20 months?
