Truck is tuned & deleted. Constant rotation of messages in dash along with LOUD DING DING DING. Messages that pop up are “service tire monitor system, service air bag, service trailer braking system, service anti theft system. We’ve replaced the gauze cluster, tuner, body controls module, checked all the grounds, replaced mega fuse box! PLEASE HELP! The constant ding ding ding is driving me nuts. Truck runs fine just won’t shut up!

 

post all codes in all the modules. Since you are dealing with powertrain, body, chassis and communication issues...you will need a full function scan tool that can access P , B , C and U dtc. cheap code reader won't cut it.
