Odd CAN signal - any ideas?

Post by barrieautos »

Hi All,
This scan was taken from a 2007 Land Rover Discovery. The car was in the shop for a no-start condition which turned out to be a mechanical problem with the engine.
During diagnosis I recorded the attached wave form, which I found interesting.
Can anyone suggest what would cause the drop in voltage, particularly in the recessive state?
It seems that this had no significant effect on bus operation.
I no longer have access to this car, so can't perform any more testing, sorry.
Thanks,
Ron
