Need help with Emission status five IM - Monitors are Not Ready.

What is your question?

I saw a post where DanD answered: I just went through this with another 1996 Mercedes. I am a Calif. Smog Tech that works at a Gold Shield Station ( means that the State sends us cars that other shops have struck out on ). The Mercedes had several problems. The dealer did, in SF did not even know how to work on the problem The car was broken/malfunctioning for 4 years. What I found is that there is a separate computer that only does the OBD-II monitors. It is called the Diagnostic Monitor or module.The Dealer does not even know where it is in the car because I called several, all over the US, they think it is built in to the main Engine Computer. IT IS NOT!!. The computer is usually in the Engine Fuse Compartment by the round Mercedes Diagnostic Connector. It may even say CARB on it. California Air Resources Board which mandated its existence. The Factory did not even know about it. I had to get it from a special German parts person and it was a used one to boot. However, this definitely fixed the problem. Let me know about this because there are several things to check before putting in this computer, like do you automatic door locks work OK? I will explain why this is so important later. - Can Dan provide more info as to where is the CARB module and what could be preventing the IM Monitors from setting to Complete? Thank you, Jorge
