If you own a Honda Pilot and have encountered the “Keyless Start System Problem” error message on your onboard dashboard, you’re not alone. In this article, we will discuss the five most common causes of this issue and provide solutions for fixing it.

Cause 1: Malfunctioning Start Stop Button

The most common cause of the “Keyless Start System Problem” error message in the Honda Pilot is a malfunctioning start stop button. This issue can easily be resolved by replacing the button. To do this, you’ll need to follow a few simple steps:

  1. Snap out the bottom panel and the panel above the start stop button.
  2. Locate the push tabs behind the start stop button and push them in to release the button.
  3. Disconnect the wiring harness connected to the back of the button.
  4. Install the new start stop button by reversing the above steps.

Replacing the start stop button is a straightforward process that can be done by most DIY enthusiasts. You can find replacement buttons on online platforms like Amazon or eBay.

Cause 2: Low or Dead Key Fob Battery

Another common cause of the error message is a low or dead battery in the key fob. While this issue may not always trigger an error message on the dashboard, it’s worth considering if you’re experiencing the keyless start system problem. To fix this, follow these steps:

  1. Open the key fob case using a prying tool.
  2. Replace the old battery with a new one.
  3. Close the key fob case.

Swapping out the key fob battery is a simple task that can rule out a battery-related issue.

Cause 3: Blown Fuse or Bad Relay

The Honda Pilot has three fuse boxes, two in the engine compartment and one under the dash. Some fuses and relays in these boxes are related to the starting system of the vehicle. If you have already addressed the start stop button and key fob battery but the issue persists, you should check the fuses and relays. Here’s what you need to do:

  1. Locate the fuse boxes in the engine compartment and under the dash.
  2. Inspect all the fuses and relays connected to the starting system.
  3. Replace any blown fuses or faulty relays.

Ensuring that all fuses and relays are in good condition is essential to rule out electrical issues.

Cause 4: Wiring Problems

Wiring problems can also be the culprit behind the keyless start system problem. A short circuit, an open circuit, or a bad connection can trigger this issue. The area behind the start stop button is the most vulnerable to wiring problems. Check the wiring and ensure that all pins are securely connected. If you discover any loose or damaged wires, it’s advisable to seek professional help. Wiring problems can be difficult to troubleshoot without proper expertise.

Cause 5: Faulty PCU (Power Control Unit)

Though rare, a malfunctioning PCU can cause the keyless start system problem in your Honda Pilot. The PCU is the onboard computer responsible for controlling various systems in the vehicle. If you have exhausted all other potential causes and the issue persists, it’s possible that the PCU needs to be replaced. However, diagnosing a faulty PCU requires professional assistance.

In summary, the “Keyless Start System Problem” error message in a Honda Pilot can be due to various causes. The most common solutions include replacing the start stop button, checking the key fob battery, inspecting fuses and relays, troubleshooting wiring problems, and addressing a faulty PCU. If you are unsure about any step in the troubleshooting process or need clarification, please refer to expert instructional videos or consult a professional.
