Problem overview

Some Dodge Ram 3500 owners report experiencing issues with the ABS, check engine, and brake lights being illuminated, along with non-functional odometer and speedometer. These problems may indicate that the Anti-Lock Braking System is not functioning properly, potentially due to a blown fuse, dirty wheel speed sensors, low brake fluid, or issues with the ABS control module. Additionally, the check engine light may signal engine-related problems, while the brake light's presence alongside the ABS light suggests a critical malfunction in the braking system, impacting safe driving. Furthermore, non-working odometer and speedometer readings could be linked to the ABS malfunction or other electrical issues, such as corroded terminals or damaged wiring. If owners are unable to resolve the ABS module issues themselves, it is recommended to consult a trusted mechanic for a thorough diagnosis and repair to ensure the vehicle's safety and performance.
