Service bulletins for the 2024 Ram 2500
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

| 9100487 | 2025-01-15. Service bulletin. STEERING. MODULE Steering Control Before replacing the steering column control module (SCCM) due to turn signal inop, wipers inop, steering controls inop, TCS light DTC C0051 or horn blowing while turning, please follow these steps: 1.- Refer to service library procedure and follow diagnosis steps. 2.- If failure still present, make sure all the switches', horn's, airbag's harness are properly connected and there is no corrosion or pinching, disconnect the switches & reconnect them, and reverify the issue. 3.- Verify if failure is still present, review if there is lack of communication between SCCM and BCM. For example, activate turn signals or wipers. 4.- Read at the BCM diagnosis session if BCM is receiving information from SCCM. Through diagnosis review if activation from horn, wipers or turn signal is requested and are working. 5.- Disconnect the SCCM fuse for around 30s,and repeat the previous steps to see if failure still present. 6.- Do a hard reset to BCM and evaluate if any DTC is set. Retest if failure still present. 7.- Before replacing the SCCM disconnect it and reconnect it again. If there are no DTC's active, physical defects, steering controls inop, wipers inop, nor turn signal inop, horn inop, then SCCM does not need to be replaced. |

| 9100465 | 2024-12-19. Service bulletin. SEATS. SEAT BELT Front Outer Seatbelt Slow Retraction / Seat Belt Cleaning If the vehicle exhibits slow seatbelt retraction, prior to replacing seatbelt please inspect for debris and any build up on the webbing and DRing. If evidence of debris and build up, please clean seatbelt webbing or turning loop as described below. Seat Belt Maintenance: Do not bleach, dye or clean the belts with chemical solvents or abrasive cleaners. This will weaken the fabric. If the belts need cleaning, use a mild soap solution or lukewarm water. Do not remove the belts from the vehicle to wash them. Dry with a soft cloth. Sun damage can also weaken the fabric. Replace the belts if they appear frayed or worn or if the buckles do not work properly. NOTE: If the belts retract slowly, inspect the upper turning loop for soiling. If soiling is present, clean with a wet soft cloth until all residue is removed. |
