This device clears codes, resets the check engine light, resets monitors, checks emission systems, and identifies basic car problems. Designed to quickly and easily provide diagnostic information needed by DIY users and professional technicians. Compatible with most 1996 and newer vehicles, it reads, defines, and helps you solve generic and manufacturer-specific trouble codes. No one likes car problems. Save time and money by checking your vehicle yourself. Trips to the repair facility can be expensive and time consuming for a basic issue. Some check engine lights are as simple as tightening your gas cap, super easy. Don't stress over emission tests. The AL400 has you covered. You'll be able to diagnosis and repair issues before the test ensuring a smooth emissions test. Read Vehicle Information •VIN (Vehicle identification Number). • CID (Calibration ID). • CVN (Calibration Verification Number) Graph Live Data The live graph of the data stream allows for an easy-to-understand visual representation of real-time changes including engine temperature, RPM, and more. Sturdy Durable The connection cable of the AL400 car code reader is very robust and durable, and will not be broken during long periods of normal use. DTC Look Up Library Thanks to the AL400 you know the code, but what does that code mean? With our onboard DTC look up library you can quickly find the meaning of the code without searching online. The library contains over 40,000 fault code definitions. 3-Color LED Indicators If you want to do I/M readiness detection, it is faster to use the one click detection without entering the main menu. Green indicator: No DTC (Proves that your car is not faulty) Yellow indicator: Pending DTC (Your vehicle has fault codes that have appeared before, but have not been cleared) Red indicator: Permanent DTC (The fault codes that currently exist need to be repaired before they can be cleared) Free Lifetime Updates Link to your computer to get latest and most complete data, for FREE. Review: An essential piece of kit for every car owner - I’m not a mechanic, and I usually panic if any messages show up on my XC90. I’d trawl the car to the garage and pay at least £75 for the privilege too, just to be told that I’d need a fuse replaced or to top up on coolant (the fault messages aren’t that obvious on the Volvo!) I bought this on a whim because I was having light troubles, and it arrived quite quickly. I was able to find the plug in port and the instructions were very easy to follow. Turns out, I have a defective relay for my rear lights. It was extremely easy to identify once I’d got the scanner plugged in. It will still cost me a fortune to fix, but at least I know what I’m dealing with! I really liked the option on the scanner to be able to view the emissions system of my Volvo as the MOT is coming up and I’m always scared of it failing on that. My favourite feature is being able to clear the codes. I have been trying to clear off the messages about my lights for months, and now I’ve been able to take it off and stop the distractions while driving. I’ve also booked my car in to sort out the relay switch, so it’s been really good and saved a couple of quid! I can also update the software if I need to check the other half’s car too, there’s always a newer car coming into the house. This is a portable device to keep in your glovebox, with a handy LED to help me locate the OBD slot - it’s fiddly, but I can see what I’m doing. My brother wants to borrow mine, but I think I might get him one for his birthday if he’s lucky. I don’t want to get rid of mine.
