What does it mean when it reads "C-error" on my radio screen?
Hi,
I have a 1994 C220 mercedes benz, and after re-connecting the battery from doing some mechanical problem on my car, when I tried turning on my radio, it reads "C-error" (which i believe means "code-error", possibly from entering too many wrong code too many times) and wouldnt let me punch in any numbers or code... (although i do know the code). How do i resolve this problem and get my radio to enter the code and back on working again?

Battery should be in the trunk, under the mat next to spare tire on the right side. The starter is in the engine compartment on the underside near the firewall (very close to the accelerator pedal, think: if you could put your foot through the floor with the accelerator while sitting in the driver's seat, you would end up kicking the starter). Not fun to get at from under the car! (which is the only way to get to it :(
mcdevito75 here, Simply follow the positive or RED battery cable to the starter, you could have a dead battery, dirty connections at the battery or a bad stater. You may have to tow it to the shop.
This can not be reset by conventional methods. This must be done through a scan tool. Usually only the dealer scan tool will communicate with the SRS module. If the SRS light is on you have other issues and they must be remedied before the light will go out. There is no way of knowing what the issue is without running codes with the scan tool.

hello I'm an M.B. tech.-unfortunatly after you enter the wrong code (I beleive more than 3 times) it goes into a special security mode. The only way to unlock this feature is to keep power to the unit for 24 hours. If i remember correctly there are 2 different modes. The 1st mode is a 1 hour mode, the 2nd is a 24 hour mode. Your best bet is to take it to a dealer and have them reset it for you. If the unit is still in the first mode you can hook up a battery charger and keep the key on for 1 hour ( you could also do this for 24 hours). These vehiclles have an elctric throttle motor called an E.A. actuater. These units are very problematic and are usually damaged from somebody leaving the key on for an extended period of time. If you are going to attempt to perform this reset procedure yourself I would strongly recomend unplugging the actuaster when leaving the key on. The next problem would be if it lost it's synchroniztion you would need a scan tool to resynch. it. I just wanted you to be aware of this problem so you can be prepared. If you do try to leave the key on for 1 hour you probably would be o.k. it's the 24 hours that I'm concerned with. Make sure you turn the radio on when the key is on and hook up a battery charger. Be absolutly sure you have the right code because alot of people replace these units and don't replace there old code card. Good luck
