Why does the Nissan Tiida key fault light stay on?

[McKayden]

It is necessary to check whether the battery power of the remote control is insufficient. The following is the explanation of the car fault code: 1. Car fault code: The car fault code is the fault code reflected by the car computer ECU after the car has a fault. Therefore, the car has a fault at this time and the fault light stays on at this time. To completely eliminate the fault, a professional decoder (K81, laptop computer, etc.) is required to decode, which is commonly referred to as fault elimination. 2. Types of fault codes: Fault codes include real codes, historical codes and sporadic codes. Real codes are easy to check. Historical codes, as the name implies, are fault codes left over from the past that have not been cleared, but sporadic fault codes are not fixed.
