The Filter produced up to May, 2012, can't work in Single Wire CAN mode, it doesn't transfer SingleWire packets from vechicle control units to EZS, wihch of them work in emergency mode, then it cause periodical EZS restarting.

If after (fully correct!!!) Filter Installing into EZS ML W164 or GL X164, the car will works unstable (chaotic
lights flashing, impossiblity to connect with EZS via Diags tool, the big count of CAN errors in control units), you need first make checking some control units in Luggage compartment of the car and under the passenger seat - maybe some control units works in Emergency SingleWire CAN mode because they can be wet or damaged. Examples - the rear door control module is wet often, rear SAM too.


Connection "inside EZS".

     1. Find number on a Filter board, find a photo with the necessary Filter connection pictures.

     2. Desolder (remove) the ferrite CAN noise filter from a EZS board.

             Be careful: EZS has more than one such fnoise filter! You must remove only one that is shown on a connection photo!!!

     3. Find visually on a connection photo the connection points of ground and power supply wires.

     4. Important: First wire to soldering is ALWAYS GROUND wire! 

             It will be do always to Electrostatic Discharge prevent.

     5. After ground wire soldering you can solder CANs wires and power supply wire.

             Be careful:  On some (similar at first look) Filter connection pictures, the CAN1 and CAN2 wires pairs can have different connection !!! 


Since 27.02.2023, activation of INVISIBLE mode has been added to the filters (disabling the possibility of detecting the installed filter by all sorts of "pickers" with the Cleaner program).
If you see that the installed filter is working correctly, you can make it "invisible". It stops being detected by the program in the car, as if no filters in this car.
At the same time, "on the bench" without a car, it continues to be detected by the program. Activation of the mode by two methods.
Method 1, manually: solder the jumper M2 on the filter pcb. Deactivation - remove the jumper M2.
Method 2, via MB-Cleaner. In the filter window, after detecting the filter, set a checkbox "INVISIBLE" (near "UNLOCK"), then click MAKE to start the process.
Reset the invisibility mode to normal mode - only on the bench (without the car), through the UNLOCK filter procedure.


Please correctly select pictures and the Filter connections!

Please do not ask us for pictures of connecting EZS-Cluster filters for modern cars! It does not require a filter, but a procedure ofl Unlock the Cluster!
The clusters unlocked by our means (purchase/replacement of MCUr or with the MB-Unlocker program) do not require the installation of the EZS-Cluster filter.

Caution! It's for B-CAN Filter connection (M-class, GL-class W164, X164)!

If one of car control units have some bus faulty by Body CAN (emergency SingleWire CAN mode working), then after installing Filter (without SingeWire working future) the Body CAN bus can be work very unstable - Filter presence aggravates malfunction in the car CAN bus. For it's preventing we have for you the filters 1816-12 for cars W164-like with slow-bitrate CAN with working possiblity in SingleWire emergency mode. Overwise you must found and fix mailfunction on car CAN bus using some special tools, on example - Star Diagnosis (CAN bus System Diagnosis option in StarDiags menu).
