C220 fault code
I have a 1995 c220 with a "100-CAN no signal from the dm" code in the computer. I am using an AST retriever from the 38 pin diagnostic plug. My best guess looking over the wring diagram is the OBD2 Diagnostic Module has a problem. My mitchel wiring diagram says the module is in the center rear of the engine comp. I have looked all over the engine compartment withut any luck. Does anyone know where this module is located?
Looking over the wiring diagram I cannot find any obvious power to the module. It could be comming from the Engine control module on a green/red or yellow/red wire. I hope to check there for power in when I can find the module. Any help will be apreciated. Thanks John |

Thanks I will look under the drivers side kick pannel. I also looked in the dm part of my retrievers live data capabilities and it said the dm had no inputs or something to that extent. I will keep you posted. John

The computer seems to be fine. I disconnected the computer and then reconected it and the problem went away. The car has run fine for about 3 months now. Thanks for the location of the computer. John
