The solutions for weak ETC signal are: 1. Reserve a cutout for ETC when installing metal film; 2. Replace with a new ETC device; 3. Change the installation position of the ETC. The installation method of the ETC device is: 1. Purchase the ETC device, check if the equipment is complete, and read the installation manual; 2. Determine the installation direction of the ETC device, with the solar panel facing outward; 3. Peel off the back adhesive of the device, fold the solar panel towards the vehicle's front windshield, and press firmly to ensure secure attachment; 4. Install the device at the center top of the vehicle's front windshield, ensuring it does not obstruct normal driving visibility. It should be adhered in one go and not removed for reattachment; 5. Insert the ETC card to activate the ETC device. Upon hearing a beep from the device and seeing the indicator light turn on, the device is activated, and the installation is complete.

I've encountered weak ETC signal issues several times while driving, especially on remote highways or during rainy days. The solution is to start with basic steps: check if the ETC device is properly mounted in the center of the windshield, ensuring window tint or navigation devices aren't blocking the signal. If the signal remains consistently weak, I try reinstalling the device, tightening the battery compartment, or simply replacing the battery (easily purchased online for DIY replacement). When approaching toll stations, I slow down, avoid lane cutting, and maintain steady traffic flow. I use the customer service app to check device status – they can diagnose issues and provide remote guidance. Always carrying cash as backup prepares me for ETC failures. Developing a pre-drive inspection routine and weekly dust-cleaning habit significantly reduces signal problems. Remember safety comes first – if signals are weak, patiently wait or use manual lanes. ETC devices have limited lifespan; replacing aging units with newer models prevents headaches.

Can the car still be driven if the ignition coil is faulty?

If the ignition coil is severely damaged, causing too many cylinders to misfire or adjacent working cylinders to misfire simultaneously, the engine will not start normally and the car cannot be driven. If the ignition coil only weakens the spark plug's ability to fire, the vehicle can still be driven normally. Additional details: As a core component of the engine's ignition system, the car's ignition coil intermittently converts the vehicle's low-voltage electricity into high-voltage electricity. If the engine lacks the high-voltage electricity generated by the ignition coil, the combustible gas mixture in the cylinders will not be ignited, and the engine will not function properly.
