1. Malfunctioning Start Stop Button

The start stop button is the most common culprit behind the “Keyless Start System Problem” error message. If your button has malfunctioned, it needs to be replaced. This problem is prevalent among Honda Pilot owners, as discussed in various forums. Fortunately, swapping out the start stop button is a fairly straightforward task that can be done by most DIY enthusiasts. Follow these steps to replace the button:

  1. Snap out the bottom panel of the dashboard.
  2. Snap out the panel covering the start stop button.
  3. Locate the push tabs behind the button and push them in to release it.
  4. Disconnect the wiring harness attached to the back of the button.
  5. Remove the old button and replace it with a new one.
  6. Reconnect the wiring harness and snap the panel back into place.

You can easily find replacement start stop buttons on online platforms like Amazon or eBay. They are not excessively expensive, making this fix a cost-effective solution to the issue.

2. Low or Dead Key Fob Battery

Another possible cause of the “Keyless Start System Problem” is a low or dead battery in your key fob. Although this issue usually triggers a separate message on the dashboard, it is still worth ruling out as a potential problem. Swapping out the key fob battery is a simple process that can be completed in a few steps:

  1. Pry open the case of the key fob.
  2. Remove the old battery.
  3. Insert a new battery.
  4. Close the key fob case.

If you are receiving the error message alongside the keyless start system problem message, replacing the key fob battery is a good starting point to address the issue.

3. Faulty Fuse or Relay

The Honda Pilot has three fuse boxes: two in the engine compartment and one located beneath the dash. Various fuses are connected to the vehicle’s starting system, and multiple relays work together to ensure its proper functionality. A blown fuse or a faulty relay can potentially cause the “Keyless Start System Problem” error message. If you have already replaced the start stop button and key fob battery, it is advisable to inspect the fuses and relays in all three fuse boxes. Ensure that none of them are damaged or blown. Replace any faulty fuses or relays as necessary.

4. Wiring Issues

Wiring problems can also trigger the “Keyless Start System Problem” error message. Issues such as open circuits, shorts, or bad connections can disrupt the proper functioning of the system. The wiring behind the start stop button is particularly susceptible to problems. To check for wiring issues, carefully examine the wires behind the button. Ensure that all pins are securely connected and none of them are protruding or loose. If there are any wiring problems and the pins appear to be in good condition, it is recommended to seek professional assistance, as troubleshooting wiring problems can be challenging.

5. Faulty Onboard Computer (PCU)

While rare, it is possible for the onboard computer (PCU) of your Honda Pilot to have a malfunction or error, leading to the “Keyless Start System Problem” error message. Typically, onboard computers do not fail, but if you have exhausted all other possibilities and the error persists, it is worth considering this as a potential cause. At this point, it is best to consult a professional who can diagnose the issue accurately and advise on the necessary steps for repairing or replacing the PCU.

Conclusion

In conclusion, the “Keyless Start System Problem” error message in your Honda Pilot can stem from various causes. The most common culprits include a malfunctioning start stop button, low or dead key fob battery, blown fuse or faulty relay, wiring problems, and a faulty onboard computer. By following the step-by-step instructions provided in this article, you can identify and resolve these issues effectively.
