The “check computer” light

October 26th, 2011

On my way to work this morning my car’s check engine light came on. This is not an uncommon event, my car eats batteries and when the battery starts to fail and the car has trouble starting the light will come on. A few days later it generally clears itself. The couple times that the light has not cleared itself I have actually had to take it in to have it looked at.

This morning when it came on I suggested to my carpool buddy that I wished a built in feature of cars was to tell me why the light came on. Seems ridiculous to make me take it to someone to tell me what’s wrong with my car. Imagine if we had to take our computers to someone any time there was an error message in /var/log/messages. What a pain.

Ha! Take that car analogies of computers! I just made a computer analogy of cars!

I know you can buy those readers that will tell you the error codes. Although, my car is a VW that takes a non-standard reader and is more expensive than the common ones. Ah, German engineering.

(For my non-linux cohorts, /var/log/messages is the system log in linux)
