Troubleshooting Honda Hands Free Tailgate Systems

It's the most convenient having a hands-free tailgate system having no worries about dropping groceries or tailgate accessories. This is what Honda tailgate feature is meant to do. However, it is very frustrating when the feature stops functioning. The tailgate system is meant to be a convenience addition to the Honda model, but when there's a system malfunctioning it can be a pain. Be it service center working with Honda customers or a parts wholesaler trying to figure out the problems, it is very important to know the workings of the systems. This guide focuses on the most common issues and answers to problems with Honda Hands Free Tailgate Systems.

Common Problems with your Automotive System

The first sign of a malfunctioning system is a total lack of response. You stand there, patiently kicking your foot under the bumper, but the tailgate stays closed. Other times, the system seems to work, but is erratic. It may open and close on its own, partially opening, and can even make odd, grinding noises. Occasionally, even when the power tailgate works, the motion detection sensor fails and the function is unresponsive entirely. Simple sensor blockages, and other more complex issues, can cause these problems. Your symptom identifiers determine the diagnostic approach. Employees and clients of businesses selling automotive parts can take advantage of the quick identification of these problems patterns.

Basic Checks and Simple Fixes  

You must begin by taking basic checks. Simple steps have been known to give an answer to a surprising number of issues. First off, make sure that the vehicle's ignition is on the right position, "ON". The engine is running and the system disables for safety if the vehicle is in gear, and if the vehicle is running. You will need to check the block that is covering the rear bumper. Dirt, mud, ice, and a har trailer hitch can block the motion sensors. A proper washing could be all that is needed. You must also check the tailgate that is manually operated. If the power to open and close is not functioning correctly, then the problem can be more than the hands-free module. Lastly, confirm the vehicle's battery. A weak battery can lead to many problems, including sporadic operation of features like the hands-free system.

Issues with Sensors and Calibration

The sensors, which are usually located on the rear bumper, are the most important component of the hands-free system. They should be inspected first if the basic checks do not resolve the issue. Failures can be caused by physical damage of road impacts, as well as corrosion from road salt. Errors with the sensors can be pulled from the body control module with Honda-specific diagnostic scan tools. Losing system calibration is also a common issue. This can be caused by temporarily disconnecting the vehicle's battery or by system electrical glitches. The calibration process usually just requires the tailgate to be manually opened partway, and then a relearn procedure is initiated by pressing a sequence of buttons or by using a dealer level scan tool. Different model years of Honda's have different calibration steps, so determining which service manual to use is vital. For wholesale partners stocking sensors with reliable aftermarket options, or offering recalibration, are sensible service offerings for repair shops.

Troubleshooting Electrical and Control Module Issues

Do sensors calibrate, and do all systems go? If the answer to all these questions is yes, the problem could be deeper in the electrical circuitry or the control unit. Start by inspecting the wiring harness that leads to the rear sensors and the tailgate actuator. Check for any pinched, frayed, or corroded wiring, especially in the areas that flex, such as where the tailgate hinges are located as these are critical. A multimeter is a must here as you need to check for power, ground, and signal continuity. A main control module is also a possibility but is uncommon and may need a professional to correctly diagnose the following issues. Other linked systems such as the vehicle's keyless entry system or a faulty latch mechanism may contribute to the problem and indirectly disable the hands-free function as a safety feature. Understanding these interconnections is key in troubleshooting support to your customers.

'Active Maintenance' and The Conclusion  

When it comes to diagnosing problems with a Honda hands-free tailgate system, the logical conclusion is to begin with the simple and work towards the complex. While some repairs and fixes are within the capacity of a DIY, most problems require a level of expertise and professional equipment, and in these cases, reliable aftermarket parts suppliers are necessary partners for repair shops. In order to minimize the occurrence of problems, active maintenance is necessary. This includes sensor area and tailgate strut maintenance to ensure that the tailgate can move freely. Furthermore, maintenance is necessary for any electrical components that might be present. This active maintenance is a good for automotive wholesale companies in order to understand the common system faults and build B2B client relationships in order to deliver the right aftermarket components which might include the system's sensors, electrical wiring, or control module to ensure a hands-free tailgate system is available to end users in a variety of global locations.
