Mercedes non-start issues
-
Your Mercedes' key(s) are not being recognized by the ignition switch (EIS) could be due to a number of different causes.
-
Key hardware/software failure.
-
Your Mercedes' key(s) contains two of the most important components which also happen to be the most vulnerable to failure.
-
The key coil is the component that allows the key’s data to be read by the ignition switch. If this component fails or breaks, it will cause the key to become ‘dead’ when inserted into the ignition switch.
-
Sometimes the hardware is completely fine, but, the NEC chip which holds the key’s data may get data corruption and again cause the entire key to become useless.
Electronic Ignition Switch (EIS/EZS) failure
The Mercedes electronic ignition switch EIS/EZS is the next culprit on our list of causes of non-start in Mercedes-benz vehicles. The EIS fails due to software (eeprom/flash) corruption and also hardware issues such as the EIS coil, IR receiver or processer (MCU).
Electronic Steering Lock (ESL/ELV) failure
The electronic steering lock is located on your Mercedes’ steering column. It has two main failures, the first is a mechanical failure where the motor which locks and unlocks the steering looses power and stops responding to the request from the PCB on the ESL. The other is the data stored within the NEC/Motorola processors on the ESL PCB, this could become locked and cause the ESL to become ‘dead’ altogether.
ESL/ELV problems are very common on the following vehicles:
-
Mercedes C class (W204)
-
Mercedes E class Coupe (W207)
-
Mercedes E class (W212) with ESL
-
Mercedes GL (X204)
