90023502022-07-18. Service bulletin. SERVICE BRAKES; ELECTRICAL SYSTEM; EQUIPMENT. Part Description: Integrated Trailer Brake Module Issue Description: Before replacing an Integrated Trailer Brake Module (ITBM) please review the following items.~ 1. The ITBM does not control the trailer lights. If the trailer lights are not working, do not change the ITBM.~ 2. If the Diagnostic Trouble Code(DTC) reported by the ITBM is C10C7-11 "Electronic Trailer Brake Control Output Short to Ground" or C10C7-12 "Electronic Trailer Brake Control Output Short to Battery", please verify the wiring on the trailer. The purpose of this faults is to protect the ITBM output from faulty trailer wiring.~ 3. If the customer complaint is ITBM not detecting the trailer connection. Do not change the ITBM until the system has been verified with load simulation and confirmed that ITBM is not recognizing the load. If load simulation indicates that the ITBM is operating properly, please verify the trailer wiring.~ 4. ITBM output will not be available if a trailer is not connect and plugged into the vehicle. The ITBM must detect a trailer before you will get trailer brake output.~ 5. Please follow the service manual procedures before changing the ITBM.~ This part can only be used as a replacement on vehicles with the Integrated Trailer Brake system already installed. Do not attempt to use this module for the purpose of adding the Integrated Trailer Brake system to a vehicle that was not originally equipped. You will encounter configuration difficulties. MOPAR has developed a kit, part number 82212548 to be used for installation of the Integrated Trailer Brake system on vehicles.

N260606132021-03-22. Service bulletin. AIR BAGS; POWER TRAIN. New Safety Recall Advanced Communication ? N26060613 Chrysler Group LLC (Chrysler) announced a safety recall on certain 2012 model year (DP) 4500/5500 series RAM 4x4 Trucks. Some of the above trucks may have a front axle with improper axle tube-to-differential housing welds. If the axle tube welds fail, the front axle differential housing could rotate relative to the axle tubes. This could cause the front propeller shaft to bind up or fracture the front propeller shaft universal joint. Chrysler will conduct a voluntary safety recall on all involved vehicles to either replace the front axle or install an axle brace to prevent differential housing rotation. Dealers will be notified of the launch of this safety recall by way of established methods used in the past. We ask that you please take the time to ensure that your personnel are aware of this communication and are prepared to execute a customer friendly process for inquiries on involved vehicles.
