What causes the reverse light of the Lavida automatic transmission not to light up?
2 Answers
Lavida automatic transmission reverse light does not light up for the following reasons: Fuse blown: When the reverse light does not light up, the first thing to consider is that the reverse light fuse is blown. The reverse light fuse for most cars is located inside the dashboard. Follow the instructions on the fuse box to locate the reverse light fuse, and you can pull out the fuse to check if it is blown. Reverse light bulb failure: If the filament of the reverse light bulb is broken, even if there is power, the reverse light will not light up. Checking the reverse light bulb is relatively simple; just remove the tail light and take out the bulb to see if it is functioning properly. Reverse light switch failure: The reverse light will only light up when the reverse light switch is properly engaged. Unplug the reverse light switch connector and use a wire to bypass the switch. If the reverse light lights up, it indicates that the reverse light switch is damaged. If it does not light up, the switch is not the issue.
I once encountered an issue with the reverse light not working on my Lavida automatic transmission model. After checking it myself, I found there could be several possible causes. The most common one is a burnt-out bulb, as reverse light bulbs have a limited lifespan and are prone to damage on bumpy roads. Another frequent fault is a blown fuse—try replacing the reverse light fuse in the engine compartment's fuse box. Wiring issues like short circuits or loose connectors can also interrupt the signal, especially in older cars where wiring tends to degrade. In Lavida automatic models, the reverse light is linked to the transmission position sensor; if the switch fails, the light won't illuminate, which is more common in older cars with gear wear. Another risk is unstable vehicle voltage—if the alternator regulates voltage too high, it may damage components. So, I'd start troubleshooting by simply replacing the bulb, then use a multimeter to test the wiring if needed. Don’t underestimate it—reverse lights are the eyes for nighttime reversing, and once they fail, they can easily lead to scrapes or accidents.
