What does the service engine light mean on an Infiniti soon?

Contents of the material

What to do if the sign SERVICE ENGINE SOON (SES) lights up (blinks)?

This inscription on the instrument panel indicates that there is a malfunction in the car.

Technical Center Infinity Parts produces diagnostics and repair any vehicle systems.

First, you need a professional diagnosis of Infinity. Now the most important thing is the correct diagnosis, otherwise you pay!!! incompetence of a specialist and elimination of a non-existent breakdown.

And we have more than enough such cases: clients come from services where non-existent faults were repaired for them, and then they shrugged.

And self-diagnosis is like self-medication…

Therefore, we wanted to post Infiniti fault codes on the website – we changed our minds!

It’s not a pity – it won’t help, it may even harm! Instead of this…

What’s in fact:

It is very important to understand that SES is not a cause, but a consequence of a malfunction. Using special devices or simply disconnecting the battery for a long time (about 20 hours), the error can be erased and SES will go out, but this will not eliminate the problem.

Even if you probably know the reason for the appearance of SES and it has been eliminated (for example, the gas tank cap was not tightened enough – you tightened it), but SES remains on, you cannot drive!

Another, more serious malfunction may occur, but you won’t know about it – SES is already on…

You need to visit a dealer or Infinity Parts, for example.

Insist on recording the detected fault codes (a Consult printout or at least entering the codes into the work order. In the future, if the fault cannot be eliminated immediately, they can be of great help in troubleshooting, including at another service.

It is always necessary to carefully analyze error codes with the help of specialists, relying on their knowledge, experience and service manual (repair book).

The computer “sees” only the electrical component of the car; it cannot diagnose breakdowns or mechanical damage to parts, but indirectly, through sensor readings, a “big-headed” specialist will be able to find the fault.
