What is EC on Mercedes Benz?
Ec means economy, which means it shuts the ac compressor off, in order to get better fuel economy. I prefer to run in auto mode, it runs the compressor even in the winter, which helps a great deal in keeping condensation off of the inside of the windows.
Can you reset the ECU on a Mercedes C class?
Modern cars like the Mercedes-Benz C-Class “learn” your particular driving style over time and miles driven. For those who have acquired a used car and want it tailored to their own driving style, or those who just simply want to start over, resetting the ECU (engine control unit) is a good way to go.
How does the climate control reset work on a Mercedes Benz?
The reset works as follows: With the key in the ignition and in posistion 2 push both the defrost button and the recirc button (at the same time) for five seconds or untill the led lights in those buttons begin to flash. Wait for 30 seconds or untill the led’s stop flashing.
Why does the EC button not turn on?
“If you have a control unit where the EC button remains illuminated you most likely have a stored DTC code or a version coding error for refrigerant level sensor. In order for the compressor to be turned on DTC codes need to be cleared and the coding needs to be corrected.”
Why does the EC light stay on all the time?
The EC light stayed on all the time. I replace the evap temp sensor and reg temp sensor, thanks to sleepwalker’s help. Then I recharged the system with freon and 46 PAG oil. By the way you must get the compressor to come on to charge the AC if your’s won’t come on, then hold down EC and Rest until the EC light goes off, the compressor will kick on.
