Fault Code Tables
I read the article in the DIY section on evaluating electronic engine controls. It was very useful and allowed me to use an alternate method to the duty cycle approach I had been using. The car (1990 300 SEL) seems to run fine but the check engine light is on. The fault codes are 7, 10, and 27. I would appreciate it if you could tell me where I can find the fault code tables. They do not appear in my Mecedes Manuals (CD version).
