This special function gives the possibility to

• Read the engine control unit’s EEPROM together with the PIN code and component security

• Read and modify mileage of the engine control unit

• Turn the immobilizer ON/OFF

• Learn keys with prepared transponders

• perform diagnostic on the engine control unit and the immobilizer.

NOTE: It is only possible to connect to the engine control unit and immobilizer for VW Crafter vehicles. To connect to any other device you will need the ABRITES Diagnostics for Mercedes.

Starting this special function brings the following dialog

From these buttons it is possible to perform the following actions

• When pressing “ECU EEPROM” the same dialog as in the “Engine control unit” is brought to the user and it is possible to read EEPROM, read mileage and bypass the immobilizer from here. You do not need to select any engine type, it is done automatically

• Pressing “Key learning” will bring the “Key learning” dialog, the user is not required to select a model, it is selected automatically

• “Engine control unit diagnostic” will perform a standard diagnostic (reading identification, trouble codes, etc.) to the engine control unit.

• “Immobilizer diagnostic” will perform a standard diagnostic (reading identification, trouble codes, etc.) to the immobilizer.

NOTE: If the car doesn’t have any working key it is not possible to turn ignition ON, respectively to get communication with the engine control unit over OBDII because the gateway (the EZS in this case) is not gating the CAN messages to the engine control unit if no valid key is recognized. So if you have a car without any valid key, you will need dismount the ECU and connect it on a table, or to connect the CAN wires of the ECU directly to the interface.

NOTE: For the key-learning it is needed to turn ignition ON with the valid key before starting the procedure. If there is no valid key, simply put the key into the ignition lock, the key-learning procedure will take about 5 minutes in this case. When the procedure is finished you will need to turn ignition ON with each key which you want to learn.

NOTE: Sometimes during communication with the immobilizer it is possible to lose communication with it, so you will need to repeat the procedure.
