2016 Ram 2500 Cruise Control Not Working

The cruise control feature on the 2016 Ram 2500 is designed to make driving easier and can be incredibly useful in certain conditions. Unfortunately, it is not uncommon for this system to fail and cease functioning properly. If your 2016 Ram 2500 cruise control is not working, it may be due to a variety of issues. This article will provide an overview of common causes of non-functioning cruise control, as well as preventive maintenance and repair tips. With understanding, you can determine the best course of action in order to get your cruise control feature back up and running again.

Check the Fuses

If you are having trouble with the cruise control in your 2016 Ram 2500, the first thing you should check is the fuses. The fuses for the cruise control system are located under the hood, in fuse box. Remove each of these fuses one at a time and inspect them for signs of corrosion or damage. If they look good, then reinstall them in their correct positions. Once all of the fuses have been checked, it’s time to move on to the next step.

Do a Voltage Test

Next, you’ll need to do a voltage test on your 2016 Ram 2500 cruise control system. To do this, use a multimeter and set it to read DC volts. Connect one of the leads from your multimeter to one of the terminals on your vehicle’s battery and then connect the other lead to one of the terminals on your cruise control module. Make sure that all connections are secure before taking any readings. Once you’ve taken these readings, compare them against manufacturer specifications for voltage output and make any necessary adjustments or repairs as needed.

Replace Worn or Defective Parts

In some cases, worn or defective parts may be causing problems with your 2016 Ram 2500’s cruise control system. These parts include relays, vacuum motors, electrical connectors and wiring harnesses. If any of these components are found to be faulty or damaged, they should be replaced immediately with new ones from a trusted automotive supplier or dealer. Additionally, if any electrical connections appear corroded or frayed, they should be cleaned and repaired as needed before further testing can take place.

Programming Problems With Computer Modules

Computer modules can sometimes cause issues with certain components in vehicles such as the cruise control in your 2016 Ram 2500. If this is suspected to be an issue with your vehicle’s system, it may be necessary to update both its firmware and software programs as well as reprogramming it for optimal performance. This process should only be undertaken by qualified individuals with access to appropriate tools and diagnostic software programs designed specifically for use with electronic systems such as those found in vehicles like yours.

Malfunctioning Modulator/Solenoid Assembly

The modulator/solenoid assembly is responsible for controlling various functions within vehicles such as those related to their cruise control systems like those found in your 2016 Ram 2500 pickup truck. When this component fails or malfunctions due to wear and tear over time, it can cause issues such as erratic behavior when attempting to operate its related functions including setting speed limits on cruises controls systems like those found in modern trucks like yours today. To diagnose this problem correctly it may require inspecting for error codes using an appropriate diagnostic tool along with checking all continuous duty relays associated with its operation which should provide more insight into its current state of operation if additional testing is needed afterwards

Air Leakage in Vacuum System

When diagnosing a 2016 Ram 2500 with an issue of cruise control not working, one of the first steps is to look for any air leakage in the vacuum system. This can be done by repositioning hoses and connections, inspecting for broken or cracked hoses, and looking for any frayed or split wiring insulation around vacuum motor harness connectors.

Failed Cruise Control Clutch Discs or Switches

The next step is to check the cruise control clutch discs and switches. This includes inspecting steering column switches and cables to confirm that they are disconnected at actuators. It is also important to check the cruise control actuator vacuum supply, making sure that all hoses are performing correctly.

Electrical Grounding Issues With Vacuum Motors

Finally, if all else fails, it may be necessary to inspect the electrical grounding issues with the vacuum motors. This involves looking at wires, terminals, ground joints and bolts, and repairing where necessary. In some cases, it may even be necessary to replace parts of the system if they are too damaged or corroded.

By thoroughly checking each of these areas when diagnosing a 2016 Ram 2500 with a cruise control not working issue, it is possible to identify and fix the problem quickly and easily.

FAQ & Answers

Q: How do I diagnose a cruise control problem?
A: The first step in diagnosing a cruise control problem is to check the fuses. If the fuses appear to be functioning correctly, then you should perform a voltage test. If the voltage test does not indicate any problems, then you should check for electrical connectivity issues, programming problems with computer modules, malfunctioning modulator/solenoid assembly, air leakage in the vacuum system, failed cruise control clutch discs or switches, and check the cruise control actuator vacuum supply. Finally, you should inspect all wires, terminals and ground joints for electrical grounding issues with the vacuum motors.

Q: What parts may need to be replaced if my cruise control is not working?
A: Depending on what diagnostic steps are taken and what issues are discovered during those tests, several parts may need to be replaced. This could include relays, vacuum motors, connectors and terminals that are worn or defective. In addition, you may need to update firmware and software or perform reprogramming on computer modules if there are programming problems detected.

Q: How can I fix air leakage in my vehicle’s vacuum system?
A: Air leakage can cause problems with your vehicle’s cruise control system. To fix this issue, you should reposition hoses and connections and look for broken or cracked hoses. You should also inspect steering columns switches and cables to confirm disconnection at actuators.

Q: What should I do if the continuous duty relays are malfunctioning?
A: If the continuous duty relays malfunction then it can affect your vehicle’s cruise control system. To address this issue you should inspect for error codes related to the relays as well as check all of their individual components for wear or damage that could be causing them to malfunction. In addition, you should also check all wiring insulation around vacuum motor harness connectors for fraying or splits that could be causing an electrical short circuit.

Q: How can I tell if there is a problem with my vehicle’s electrical grounding?
A: Electrical grounding issues can cause problems with your vehicles cruise control system as well. To determine if there is an issue with your vehicles electrical grounding you should inspect all wires, terminals and ground joints for faulty connections or corrosion that could be causing an interruption in power flow. You may also need to repair any broken bolts or replace any worn-out components that could be affecting your vehicles electrical grounding system.

In conclusion, the 2016 Ram 2500 Cruise Control Not Working issue is likely due to a faulty module or wiring issue. To identify and fix the problem, it is best to consult a qualified mechanic or technician to run diagnostics and make any necessary repairs.
