where is the fuse

 

Hello all,
I am new to this forum & am looking for a little advice. I have a 2004 C240 which has been parked in my garage for several months. Yesterday when I went to start it, it would not recognize the key. Nothing happens when I put it in the EIS. I have read that battery voltage may be the problem. I show 12.4 volts on my volt/ohm meter across the terminals. Has anyone else experienced this kind of problem?
Thanks.

 

This is one of those discussions that can go back and forth between the key/eis/or steering lock. Techs that don't have a good understanding of exactly how the system works can have a difficult time diagnosing. There are two guided tests that I feel need to be performed to accurately diag which specific component is the most likely to start with. If you only have one key you pretty much need to start with another key, unless it can be confirmed that the one key you have is good and sends a plausible DAS signal. Following the DAS signal is the correct way to go, usually checking to see which component is not sending DAS is a good starting point and either it is at fault or the component that should have relayed the signal may be.
