When your Honda vehicle throws the code P0615, it can be tricky to diagnose. This code, also known as Starter Cut Relay STRLD Circuit Malfunction, can be caused by a few things. Common causes include a blown fuse, poor connections or loose terminals at the starter cut relay and the PCM, an “open” circuit between the PCM and the starter cut relay, a PCM that needs to be updated with the latest software, and a faulty PCM. While diagnosing and fixing this problem can be complex, there are a few steps you can take to get to the root of the issue.

Blown Fuse
When a Honda vehicle throws the code P0615, the first thing to do is to check the fuse. When a fuse is blown, it means it is no longer working and must be replaced. To check the fuse, you’ll need to remove the fuse box cover and locate the fuse connected to the starter cut relay. If the fuse is blown, it will need to be replaced before any further diagnosis can be done.
Poor Connections or Loose Terminals
The next step is to check for any poor connections or loose terminals at the starter cut relay and the PCM. If the link is open, it can cause the code to be thrown and the vehicle not to start. To fix this, you must remove the starter cut relay and secure the connections and terminals.

“Open” Circuit between the PCM and Starter Cut Relay
In some cases, an “open” circuit between the PCM and the starter cut relay can cause the code P0615 to be thrown. This means that there is a break in the course that is preventing the vehicle from starting. To fix this, you’ll need to check the wiring for any damage and replace it as necessary.
PCM needs to be updated with the latest software
Sometimes, the code P0615 can be thrown if the PCM needs to be updated with the latest software. To update the PCM, you must use a scanner compatible with your vehicle and download the newest software. Once downloaded, you must install the software on the PCM and reset the code.

If all the other steps have been done and the code P0615 is still being thrown, it is likely due to a faulty PCM. To replace the PCM, you’ll need to take off the old one and install the new one. Once the new PCM is installed, you’ll need to reset the code, and the vehicle should be ready to start.
Conclusion: The Necessary Steps in Fixing Honda Code P0615
Fixing Honda Code P0615 can be tricky, but it is possible with the proper steps. The causes of this code range from a blown fuse to a faulty PCM, and the solutions include checking for a blown fuse, ensuring a secure connection at the starter cut relay and the PCM, checking the wiring for any damage, updating the PCM with the latest software, and replacing the PCM if necessary. Following these steps, you can get to the root of the issue and fix Honda Code P0615.
