How to Deal with Interlock Failure in a Honda

White Honda Car

Interlock failure in a Honda can be stressful, but it is very important to fix this problem as quickly as possible so that your car will be safe and function well. The interlock system in a Honda car is designed in such a way that shifting the transmission from “Park” is not possible without pressing the brake pedal. This helps ensure that your car does not begin moving accidentally before you are ready. This function is a crucial part of the total security system of the car. However, if the interlock system is not working correctly, it can keep you from shifting the gear out of “Park” at all, so you won’t be able to drive your Honda.

Signs That Honda Interlock Is Failing

When your Honda’s interlock system begins to malfunction, there are a few telltale signs that can be observed.

  • Difficulty Shifting Out of Park: One of the easiest ways to know that the interlock system of your Honda is failing is when you cannot get the car out of “Park” even after pressing the brake pedal.
  • Intermittent Shifting Issues: Sometimes, it is not a permanent problem, but just a transient one. One minute you may be able to shift gears normally, but the next time when you try it could be hard for you. It’s as if your Honda is trying to play a prank on you.
  • Faulty Brake Lights: The brake lights are expected to come on each time you step on the brake pedal. If you do not see any sign of light when you step on the brakes, it could be the interlock system that is the problem. Brake lights are important safety features as well, so this should be looked into regardless.
  • Dashboard Warning Lights: When something is wrong, the interlock system sends a distress signal to your dashboard to illuminate the warning lights. Be on the lookout for the “Check Engine” light or any other error lights that appear to be related to the interlock system. If you see these lights, it means your car is trying to communicate with you that there’s trouble somewhere.

Steps to Manage a Honda Interlock Fault

If you’re experiencing interlock failure in your Honda, here are some steps you can take to address the issue.

  • Check Brake Lights: First, check your brake lights to see if they are functioning properly. If the brake lights do not turn on, it could be due to the brake light switch not working You may have to fit in a new bulb or change the bulb switch if it is defective.
  • Inspect Interlock Components: Visually inspect the interlock system components, including the shift interlock solenoid and its wires. Inspect for any damage, corrosion, or loose connections that may hinder the operation of the system.
  • Check for Obstructions: Sometimes, there are instances when the path of the gear shift lever and the gear selector itself are obstructed by foreign objects or debris which prevent the gear from moving out of the park position. See if there are any objects surrounding your shift lever and take them off if there are.
  • Reset the System: A reset of the interlock may be a fast solution. To reset the system, disconnect the battery for up to a minute and then reconnect. This will, in turn, clear the stored data from the car’s memory, as well as some of the temporary faults.
  • Get Professional Help: If you can not determine the problem or fix it, please call a mechanic or Honda dealer for professional help. They have the skills and the required tools to diagnose and deal with the situation effectively.
