The Honda Pilot is a popular SUV known for its reliability and advanced features. However, like any vehicle, it may encounter certain issues over time. One common problem that Honda Pilot owners may face is the “Keyless Start System Problem” error message. In this article, we will discuss the five most common causes of this error message and how to fix them.

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 replace the start stop button, you will need to follow a few simple steps:

  1. Snap out the bottom panel of the dashboard.
  2. Snap out the panel containing the start stop button.
  3. Access the back of the panel and locate the push tabs.
  4. Push in on the tabs to release the wiring harness.
  5. Replace the old start stop button with a new one.
  6. Reattach the wiring harness and snap the panel back into place.

Replacing the start stop button is a fairly simple task that can be done by most DIY enthusiasts. You can find replacement buttons on popular 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 key fob battery. While this issue usually triggers a separate message on the dashboard, it can still be a contributing factor to the “Keyless Start System Problem” error. To determine if the key fob battery is the culprit, follow these steps:

  1. Pry open the case of the key fob.
  2. Replace the old battery with a new one.
  3. Close the case of the key fob.

Swapping out the key fob battery is a simple process that can be done at home. It is recommended to rule out this issue by replacing the battery before moving on to other potential causes.

Cause #3: Blown Fuse or Bad Relay

A blown fuse or bad relay can also trigger the “Keyless Start System Problem” error message in the Honda Pilot. The vehicle has three fuse boxes, two in the engine compartment and one under the dash. These fuse boxes contain multiple fuses and relays that are connected to the starting system. To check for blown fuses or bad relays:

  1. Locate the fuse boxes in the engine compartment and under the dash.
  2. Inspect each fuse and relay, ensuring they are intact.
  3. Replace any blown fuses or faulty relays with new ones.

Carefully examining all the fuses and relays in the Honda Pilot can help identify and resolve any issues related to them.

Cause #4: Wiring Problems

Wiring problems, such as open circuits, shorts, or bad connections, can potentially cause the “Keyless Start System Problem” error message. The back of the start stop button is particularly susceptible to wiring issues. To troubleshoot wiring problems:

  1. Examine the wiring behind the start stop button.
  2. Ensure all pins are properly pushed in and secure.
  3. Look for any signs of loose or damaged wiring.

Identifying and resolving wiring problems can be challenging. If the pins are secure and there are no visible issues, it is recommended to seek professional assistance to troubleshoot and fix the problem.

Cause #5: Malfunctioning PCU

In rare cases, the “Keyless Start System Problem” error message may be caused by a malfunctioning Powertrain Control Unit (PCU). While the onboard computer of the Honda Pilot is generally reliable, there may be instances where it malfunctions. If you have already addressed other potential causes and the error message persists, it could indicate a faulty PCU. It is advisable to take your vehicle to a professional for further inspection and potential replacement of the PCU.

In conclusion, the “Keyless Start System Problem” error message in a 2017 Honda Pilot can have several causes. By checking and addressing these five common factors – a malfunctioning start stop button, low or dead key fob battery, blown fuse or bad relay, wiring problems, and a malfunctioning PCU – you can resolve the issue and get your Honda Pilot back on the road smoothly.
