Not saying you are wrong or anything, but I deleted my copy of the "service manual"... The wiring diagrams are wrong in most places, either color or pin, and the troubleshooting procedures are completely wrong. Operations of components is wrong. I'm done messing with a company's service manual when they had nothing to do with the car.

Just an FYI, the latest circle the manual had me running in was testing the cam sensor... Chrysler says the signal is pulled high when it signals. Nope, M112's and M113's pull the signal low... Had me pulling out my hair for a few days because every single step in our manual for troubleshooting resistance and shorts was wrong for that device. Same for the crank sensor.

Just my .02, the real manufacture of our car says start with a star diagnostic scan. They have more in depth procedures for testing, most of which are values they can test without ever popping the hood. I'm going to have to side with Mercedes who built our cars on this one.
