How to read your Check Engine Light codes with an iPhone
This isn’t directly about app development, but it does involve an iPhone app, so thought I’d post it. My check engine light came on recently in my 2001 Lexus ES300. I wanted to try and read the codes myself, so I did some comparison shopping and settled on the following items.
ioGeek Auto Scanner – cheaper than a lot of comparable scanners out there
The ioGeek Scanner comes with a “mini-CD”, but no paper instructions, so I just tried plugging it in and starting up DashCommand. At first I couldn’t get it to work, but it turns out that the ioGeek Scanner creates its own WiFi network that you need to connect to first. Once I did that it worked like a charm and I was able to connect wireless to it and read all the codes it was giving me.
