Will Integrated Brake Controller of 2025 Chevy Silverado 3500 Detect Electric Over Hydraulic Actuatr

Question:

I have a 2025 Chevy Silverado LT 3500 HD with a diesel motor. I am getting my 5th wheel converted from electric drum brakes to hydraulic disc brakes. I can find nothing on any EOH switch on the dash or inforcenter. I have been told that the pickup doesnt need it and will adjust/convert automatically. Is this accurate?

Hey Ken, it should detect the brake style and work automatically. But if your trailer has a solar setup let me know and there may be some extra steps.

@JamesonC Worked fine. Automatically addapted without the need of EOH switch.

I have not pulled the RV with the new brakes yet. MORryde is installing their IS system and the brakes tomorrow and half then next day.

@KenK can you report back if it worked as is? I am doing the same thing with the same truck here in a few months! I appreciate it!

I have 2025 Chevy 3500 and just purchased a 5th wheel with disc breaks and a solar setup. What are the extra steps needed?

@Sm GM released a technical service bulletin (TSB) and customer satisfaction campaign to address this issue. Dealerships can update your truck's software or replace the Trailer Brake Power Module (Part #85073615) with an updated module designed to handle voltage backfeed. Contact your local Chevrolet Dealer or GMC Dealer to have them check your vehicle for this specific campaign.
