What are the reasons for the unresponsive multifunction steering wheel buttons in the Lavida?
3 Answers
The reasons for the unresponsive multifunction steering wheel buttons in the Lavida are as follows: 1. Functional failure: Generally, the multifunction steering wheel of a vehicle includes functions such as multimedia volume adjustment, Bluetooth phone calls, and multimedia track navigation. Malfunctions or abnormalities in these functions can lead to unresponsive buttons. 2. Mechanical failure: Buttons are consumable components that wear out during use, leading to a shortened lifespan. It cannot be ruled out that functional failures and uncontrollable quality are caused by poor quality, unreasonable design, or immature manufacturing processes. 3. Circuit or connector failure: Buttons have corresponding matching circuits and connectors, plugs, etc., for electronic and electrical connections with the central control unit. Accelerated oxidation of connectors due to unsuitable usage environments, aging of wiring, oxidation of button contacts, short circuits in connectors, or virtual open circuits can all result in unresponsive buttons.
I've encountered a similar situation with my Lavida. There are usually several possible reasons why the multifunction steering wheel buttons stop responding. The buttons themselves may have poor contact due to dust, grease, or wear, especially in frequently used areas of the steering wheel where dirt tends to accumulate, preventing signal transmission. A blown fuse is another common factor, particularly if the air conditioning or audio system also stops working, as the multifunction buttons share circuit protection. Damage or loosening of the steering wheel clock spring is even more critical to note, as it connects the steering wheel to the vehicle's wiring—once it fails, the buttons stop working and the airbag light often comes on. Additionally, software faults in the body control module or unstable voltage can also trigger this issue. I recommend first trying to clean the button surfaces to see if there's any improvement; then check the vehicle's fuse box and replace the corresponding fuse if necessary. If these steps don't work, it's best to visit a professional repair shop to diagnose the clock spring and module with specialized tools. After all, this relates to driving safety, and timely action can prevent major trouble.
As a Lavida owner, I’ll share common troubleshooting steps if the multifunction steering wheel buttons are completely unresponsive. First, consider hardware damage, such as stuck buttons or broken springs, especially after sharp turns or prolonged pressing. Second, fuse issues are critical—the Lavida’s fuse box is usually near the driver’s footwell; check if any fuses are blown and replace them. The clock spring (spiral cable) failure is trickier—it’s a rotating connector for electronic circuits; if damaged, buttons may fail along with the horn or cruise control. For wiring shorts or breaks, inspect for loose or aged connectors, particularly after heavy rain or extreme heat. If the control unit (e.g., BCM module) malfunctions, a reset or software update may be needed. During DIY checks, I first use an OBD scanner to read error codes. Without tools, disconnecting the battery for a few minutes and reconnecting it might temporarily fix the issue. If that fails, visit a dealership to avoid driving risks.
