Check Engine Light Comes on After Using Remote Start: Troubleshooting Tips

The check engine light may come on after using remote start due to a malfunction in the remote start system or a related electrical issue. It is important to diagnose and address the underlying problem to prevent further damage to the vehicle.

Common Causes Of Check Engine Light After Using Remote Start

Using a remote start system can be a convenient way to warm up your vehicle before stepping inside, especially during those cold winter months. However, it can be worrisome when the check engine light comes on right after using the remote start. In this section, we will explore some of the common causes of this issue and how it can impact your vehicle.

Effect Of Low Voltage Conditions

One of the common causes of the check engine light coming on after using remote start is low voltage conditions. When your vehicle’s battery is not providing enough power to start the engine, it can trigger this warning light. Low voltage can result from various factors including a weakened battery, a faulty charging system, or even excessive use of electrical accessories while the vehicle is off.

If you notice that the check engine light comes on consistently after using remote start, it is essential to check the battery voltage. You can do this by using a multimeter or consulting an automotive professional. If the voltage is significantly lower than the recommended level, it might be time to replace your battery or diagnose any charging system issues.

Impact Of Worn Out Battery On Remote Start

Another common cause of the check engine light after using remote start is a worn-out battery. Over time, batteries naturally lose their ability to hold a charge efficiently. This can lead to a drop in voltage and cause the check engine light to illuminate. Additionally, a weak battery may struggle to power the various systems involved in the remote start process, resulting in unreliable operation.

If your vehicle’s battery is old or showing signs of deterioration, it is advisable to have it tested or replaced. A new battery can not only help prevent the check engine light from coming on after using remote start but also ensure reliable operation of other electrical components in your vehicle.

How Remote Start Can Trigger The Check Engine Light

Using the remote start feature may trigger the check engine light due to various reasons, including electrical issues or faulty sensors. If the light persists, it’s essential to have the vehicle inspected by a professional to diagnose and address the specific cause.

Regular maintenance and addressing any warning lights promptly can help ensure the vehicle’s optimal performance.

Understanding Remote Start System

Remote start systems have increasingly become popular among car owners, offering convenience and comfort by allowing them to start their vehicles from a distance. However, there are instances where using a remote start system can trigger the check engine light in your car. Understanding how this can happen is crucial to avoid any unnecessary panic or confusion.

Possible Security Code Triggers

One possible reason for the check engine light to come on after using a remote start system is due to security code triggers. Remote start systems are designed with security features that prevent unauthorized access. These security features often require a vehicle-specific security code to be programmed into the system before it can be used. If the security code is not programmed correctly or if there is a mismatch between the code and the vehicle, it can trigger the check engine light.

Here are a few possible scenarios that can cause security code triggers:

1. Incorrect code input: If the security code is not entered correctly into the remote start system, it can lead to a code mismatch and trigger the check engine light.
2. Code reset: In some cases, the remote start system may reset the security code, especially during the installation or programming process. If the code is not properly reprogrammed or synced with the vehicle’s computer system, it can cause the check engine light to come on.
3. Factory reset: Performing a factory reset on the remote start system can also result in a code mismatch, leading to the activation of the check engine light.

It’s important to note that security code triggers are just one of the possible reasons for the check engine light to come on after using a remote start system. Other factors, such as faulty sensors or wiring issues, can also contribute to this issue. If you’re experiencing this problem, it is recommended to have a professional mechanic diagnose and resolve the underlying cause to ensure the proper functioning of your vehicle.

Troubleshooting Tips For Check Engine Light And Remote Start Issues

Are you one of the many drivers who have encountered the frustration of their check engine light coming on immediately after using the remote start feature? This common issue can be attributed to a variety of factors related to your vehicle’s electrical system and engine performance. In this article, we will provide you with some valuable troubleshooting tips for addressing check engine light and remote start issues to help you get to the root of the problem and keep your vehicle running smoothly.

Impact Of Illuminated Malfunction Indicator Lamp (mil)

When your check engine light comes on after using the remote start, it’s vital to understand the potential impact of the illuminated Malfunction Indicator Lamp (MIL). The MIL serves as a warning signal for various engine and emissions system issues. Ignoring this warning can lead to more severe vehicle problems and potential breakdowns. Therefore, it’s crucial to address the root cause immediately to prevent further damage to your vehicle.

Ensuring Proper Scan For Low Voltage Conditions

When troubleshooting the check engine light and remote start issues, ensuring a proper scan for low voltage conditions is essential. Low voltage can often trigger the activation of the check engine light, causing difficulties with the remote start functionality. Utilizing diagnostic tools to detect and rectify any low voltage conditions can help restore the proper operation of both the check engine light and remote start system, ensuring optimal vehicle performance.
