Remote Start Not Working and Check Engine Light On

When you encounter a situation where your remote start is not working and the check engine light is on, it can be quite frustrating. These issues often indicate a deeper problem with your vehicle's electrical or mechanical systems. The first step is to diagnose the root cause of the check engine light. This can be done using an OBD-II scanner, which will read the diagnostic trouble codes (DTCs) stored in your car's computer. These codes can provide valuable insights into what might be causing both the remote start malfunction and the check engine light to illuminate.

One common issue that can affect both the remote start and the check engine light is a problem with the vehicle's battery or electrical system. A weak or dead battery can prevent the remote start system from functioning properly and may also trigger the check engine light. Additionally, issues with the vehicle's alternator or other electrical components can cause similar symptoms. If you suspect an electrical issue, it's a good idea to have your battery and alternator tested by a professional.

Another potential cause of these issues is a problem with the vehicle's immobilizer system. The immobilizer is designed to prevent unauthorized starting of the vehicle, and if it malfunctions, it can prevent the remote start from working. In some cases, the immobilizer system may also trigger the check engine light. If you suspect an issue with the immobilizer, you may need to have the system reset or reprogrammed by a qualified technician. This can often be done using a diagnostic tool and may require the vehicle's key to be present.

It's also worth checking the fuses and relays related to the remote start system. A blown fuse or faulty relay can prevent the remote start from functioning and may also affect other systems in the vehicle, potentially causing the check engine light to come on. Refer to your vehicle's owner's manual to locate the relevant fuses and relays, and inspect them for any signs of damage or wear. If you find a blown fuse, replace it with a new one of the same amperage rating. If the issue persists, it may be necessary to have a more thorough diagnostic performed by a professional mechanic.
