Unfortunately the reply I got from the technician at the repair shop was there is little they can diagnose without a check engine light being activated. I am speculating that the condition of most electrical/electronic parts cannot be checked without first replacing it with a new one, (charging for parts and labor) and see if that fixes it, repeat as needed.
There are no aftermarket electrical accessories installed on the vehicle.
