Common Remote Start Troubleshooting

When troubleshooting a remote start not working on a 2015 Jeep Grand Cherokee, it is important to first assess the system status. This can be done by checking the battery power, vehicle systems, ignition and fuel systems, and key fob issues.

Battery Checks

Testing and replacing the batteries in the vehicles remote start system is one of the first steps to take when troubleshooting a remote start issue. It is important to assess current battery performance and replace any weak or dead batteries in order to ensure that they are providing adequate power. If the batteries are still weak or dead after replacing them, then further investigation into other components of the system may be necessary.

Vehicle Systems

The vehicle systems should also be inspected for any signs of damage or malfunctioning components. This includes inspecting circuit boards for any signs of corrosion or wear, as well as testing electrical connectors for proper connection. Any issues found with these components should be addressed before proceeding with further troubleshooting.

Ignition and Fuel System

The ignition and fuel system should also be examined for any potential problems that could be causing the remote start not working properly on a 2015 Jeep Grand Cherokee. This includes examining all ignition components for any signs of wear or damage, and inspecting and cleaning fuel lines for debris or blockages that could be preventing proper fuel delivery.

Key Fob Issues

Another potential cause of a malfunctioning remote start on a 2015 Jeep Grand Cherokee could be due to radio frequency interference from other devices in close proximity to the vehicle. In this case, it is important to determine if there is any external interference that could be causing an issue with the key fobs signal reception. Additionally, replacing or resetting key fobs may also help resolve certain issues with remote start functionality.

Computer Issues

When diagnosing computer issues with a 2015 Jeep Grand Cherokee, it is important to determine whether the problem is software-related or hardware-related. In order to do this, a scan tool can be used to scan the vehicle’s onboard computer for any malfunctions or error codes. The scan tool will provide information about the malfunctioning component, which can then be replaced or repaired.

Spark Plug Issues

It is also important to inspect spark plugs for any damage that may be causing the remote start not to work properly. Spark plugs may become dirty over time due to carbon buildup, and this can cause engine misfires or other problems that prevent the remote start from working correctly. If spark plugs are found to be dirty, they should be replaced and/or cleaned in order to ensure proper operation of the remote start.

Driver Side Switches for Remote Start

In order to ensure that the driver side switches are properly set up for remote start, it is important to test them by turning on the ignition and activating the remote start switch. If this does not result in successful activation of the remote start, then it is necessary to inspect the starter wiring harness for any loose connections or other issues that could be causing problems with operation.

Engine Starting Problems

Finally, if all else fails when attempting to diagnose why a 2015 Jeep Grand Cherokee’s remote start is not working properly, it could be due to an issue with engine starting itself. The first thing that should be checked is the cleanliness of the battery terminals; if they are corroded or otherwise dirty, they should be cleaned in order for proper operation of electrical components like starter motors and switches. If this does not solve the issue, then an open circuit diagnosis check should be performed using a professional scan tool in order to determine what component(s) could be causing problems with engine starting.
