Mercedes W210 EZS/EIS problem?
I have a strange problem with a w210.
Key works on EIS and ESL works fine also.
Start the engine, but when taking out the key from EIS, the engine and dashboard still working. I have to disconnect battery to shut it off.
After remove key, the ESL works, but if i put it back on EIS/EZS the key don't turn anymore, just after disconnecting battery.
I read DTC's from EIS/EZS and give this code: B1156 control module electrical fault.
Any idea what could be the problem and how can I fix it?
