I have a 1998 ML320 and the check engine light is on. I bought an OBDII engine scanner, where do I connect the scanner to the car? Where is the data access port?
Its near the engine release. Grab a flashlight and place your head down where your feet go...then look up, there should be a cover that is hinged and will allow you to insert the code reader.
