The 2014 GMC Sierra is a popular choice among truck enthusiasts, featuring a powerful engine, rugged build, and impressive towing capacity. One of its most convenient features is the remote start system, which allows owners to start their vehicles from a distance, ensuring a comfortable cabin temperature before entry. However, like any technological feature, the remote start may experience issues, leaving owners frustrated. If you’re facing problems with your 2014 GMC Sierra remote start not working, you’re not alone. In this article, we’ll explore common reasons for the malfunction, provide troubleshooting tips, and discuss potential solutions to get your vehicle back to optimal functionality.
Understanding the Remote Start System
Before diving into the troubleshooting process, it’s essential to understand how the remote start system operates in your 2014 GMC Sierra. The system allows you to warm up or cool down the vehicle before you arrive, which is particularly beneficial during extreme weather conditions.
When using the remote start feature, the following sequence typically occurs:
1. When you press the remote start button on your key fob, the vehicle receives the signal through its onboard Receiver Control Module (RCM).
2. The vehicle’s computer systems engage the engine, causing it to start and run for a predetermined period (generally around 10-20 minutes).
3. If you enter the truck within that time, it’s ready to drive without needing to insert the key.
Common Reasons for Remote Start Malfunction
If your remote start system isn’t functioning correctly, various issues may be to blame. Understanding these common problems can help you narrow down the possible causes and approach the solution methodically.
1. Key Fob Issues
One of the simplest explanations for a remote start malfunction is a problem with the key fob itself. The key fob contains a battery that may run out over time. When the battery is low or dead, it may not send a strong signal to the truck to engage the remote start function.
2. Vehicle Security System Interference
Your GMC Sierra’s security system can also interfere with remote start functionality. If a security feature detects unauthorized access or a potential threat, it may block the remote start from operating.
3. Faulty Receiver or Wiring Issues
The Receiver Control Module (RCM) may be malfunctioning, or there could be wiring issues that prevent the remote start from working. Corrosion, loose connections, or damaged wires can all contribute to this problem.
4. Clogged or Malfunctioning Sensors
The remote start will only engage if specific sensors send a clear signal that it’s safe to do so. This includes checking whether doors are closed, the vehicle is in park, and the hood is secured. If any of these sensors are faulty or clogged with debris, the system may not activate.
Troubleshooting Steps
Diagnosing the issue with your remote start system requires a few practical steps. Follow this systematic approach to identify the problem.
1. Test the Key Fob
- First, check the battery of the key fob. If it’s low, replace the battery with a fresh, compatible one.
- Stand a few feet away from the vehicle and ensure that you have a clear line of sight. Try using the remote start feature again.
If this does not solve the problem, it may be time to consider other issues.
2. Inspect the Vehicle Security System
- Check if the security light on your dashboard is blinking. If it is, it may indicate that the security system is active and preventing remote start.
- Make sure all doors are closed, and that there’s nothing obstructing the closure of the hood.
3. Check the Receiver Control Module (RCM)
- Examine the RCM for any visual signs of damage.
- If you’re comfortable with electrics, check for any loose connections or corrosion at the wiring points.
In more complicated cases, you might need specialized diagnostic equipment to assess the RCM.
4. Evaluate the Sensors
- Inspect the relevant sensors mentioned earlier, such as the parking sensor, door ajar sensor, and hood latch sensor.
- Ensure none of these sensors are dirty or malfunctioning. Cleaning them may resolve the issue.
Potential Solutions
Once you’ve identified the likely cause of your remote start malfunction, it’s time to consider your options for resolution. Here are a few approaches depending on the issue.
1. Replace the Key Fob Battery
If the key fob battery was the issue, replacing it is straightforward. Simply pop open the fob, replace the old battery with a new one, and reassemble it. Test the remote start feature again to check if the problem is resolved.
2. Reset the Vehicle Security System
If the security system is blocking the remote start feature:
– Attempt to reset the system by disconnecting the battery for a few minutes and then reconnecting it.
