Jeep Wrangler JL

WARNING — 2025 Q2+ some JL Models with New ACC (DASM) Module

If your vehicle is equipped with the new Adaptive Cruise Control (DASM) module mounted on the windshield, changing to larger tire sizes will cause the system to throw a “Vehicle Configuration Mismatch” fault.
This results in warning lights on the dashboard and disabled Adaptive Cruise features.
Models without Adaptive Cruise Control are not affected.
