How A Mercedes EIS System Works

The job of the EIS is to run a series of tests when you turn your key in the ignition, which help ensure that it is the correct key. The EIS works with other components, including the ESL and ECU, to make sure that your car only starts if the key is recognized. If it isn’t the right key, your car’s “turn and start” function will be disabled. This is a great way to ward off thieves, however, a failing EIS can be an annoyance for you as a driver if you’re having trouble starting your car.

4 Common Symptoms Indicate a Failing or Faulty EIS:

  1. Vehicle won’t start
  2. Key won’t turn in the ignition
  3. Vehicle won’t start when it is cold
  4. Key only intermittently works
