PWM or CAN?
What kind of motor and mechanical load is being driven?

I did not witness the actual malfunction. It was driving perfectly fine during lunch (I was driving). But the period after that (may be 20-30 minutes after), one of the jaguars gave out. So today, I switched the drive motors to a good black one, but then same story as yesterday, the other jaguar blew out (not the black one, but a grey one). The gearboxes were cimple boxes and CIMs were used.
The diagnostics was done using the TI's Jaguar flasher. So it was daisy chained using CAN cables to the computer and the flashing software indicated a vbus fault. The motors were not driven by CAN, but by PWM.
