My guess is the parking brake mode fried the electromagnet causing the problem. Maybe maybe not.. But that is my guess. With that said maybe you ought not to tell the dealer all the details and let them just trouble shoot it. You might get all your brakes repaired under warranty. Yeah some might say that not right or correct. Maybe the PDI wasnt performed properly and the dealer failed to checker out the controller. Maybe the electromagnet was indeed faulty.. who knows but dont give the dealer all that info.. If you do plan on paying for a repair job.
I'm not going to take it to the dealer. If it turns out my controller locked up the brakes and I continued to pull it not realizing the problem, then the damage is my fault. There is no way the dealer should assume responsibility for 'my' brake controller going belly up and causing the issues.
For the past 25 to 30 years I've done my own brake work. Dealers put the screws to customers when they charge for brake work. Brakes are easy to do and after market parts are not that expensive when you shop around. Like I indicated in the OP, I'll probably end up replacing everything. just got to do the troubleshooting and figure it all out.
Most likely will end up replacing the controller with another MAX BRAKE unit. I really like the one I had. It used the trucks hydraulic brake pressure to drive the braking voltage to the trailer, was not affected by hills or vehicle level and displayed actual braking current to the trailer. I found knowing the braking current very helpful in knowing what was going on with trailer brakes.
