Why Can't the Envision Start with All Lights Flashing?
3 Answers
The Envision's inability to start with all lights flashing indicates that the vehicle is currently in an anti-theft lock state. Here is an introduction to the relevant content: 1. Anti-theft lock: The anti-theft lock is primarily designed to reduce the probability of the vehicle being stolen by others, which is also one of the important reasons why many car owners are willing to spend money on it. 2. Increasing theft difficulty: Car anti-theft is very important. Owners can also add an additional switch to the door lock to increase the difficulty of car theft. 3. Anti-theft lock levels: There are different levels of car anti-theft locks, and generally, the prices vary with different levels. Car owners can choose one that suits their actual situation.
I've encountered this situation several times. As an experienced driver who has driven over a dozen cars, when all the lights flash but the car won't start, it's mostly due to a weak battery. Especially for SUVs like the Envision, the battery may age faster, with insufficient power to support the lighting load but inadequate current for starting. Another common issue is problems with the starter relay or ignition switch, and poor wiring connections are also frequent culprits. I recommend first using a multimeter to check the battery voltage. If it's below 12 volts, the battery needs replacement. Alternatively, simply check if any fuses have blown. Don't underestimate this issue—it's more likely to happen in winter. It's best to have it tested at a reliable repair shop to avoid being stranded midway and affecting your trip.
I'm a young car enthusiast who enjoys tinkering with electronic systems. If your Envision won't start and the lights are flashing, it's likely the anti-theft system has been activated due to a sensor misjudgment causing the vehicle to lock. Alternatively, there might be a minor glitch in the control computer affecting signal transmission. You could try restarting the key or disconnecting the battery for a few minutes before trying again. I usually connect a diagnostic tool to the OBD port to scan for error codes, checking for signal errors like B1000. Also, inspect if the headlight and starter circuit connections are loose, as aged wiring harnesses might cause short circuits. Always ensure safety before working on it, and if unsure, consult a professional mechanic.
