Discussion:
Fault Code CD-7 AD-3 AD-4

Getting code CD-7 just before contactor comes in, once contactor is in the fault goes.

Every now and again I get AD-3 AD-4, I've found if I turn the truck on with the key switch the fault occurs more often than not, If I leave the key switch on and plug the battery in the fault doesn't appear.

I've swapped the drive controller positions and the fault was fixed for a while, customer has reported it is faulting again although I haven't been back to the truck yet.

Any help gratefully received

Fact of the week
The two internal cavities in our nose called nostrils function as separate organs. Each nostril has its own set of turbinates and olfactory receptors. The two independent organs work together through a mechanism called the nasal cycle, where one nostril is dominant for air intake while the other rests and is better at detecting scents.
