How can you tell that the 77960-TG7-X110-M2 is defective?

A defect on the 77960-TG7-X110-M2 shows itself through the airbag warning light in the instrument cluster, which lights up constantly or intermittently. In addition there is a fault message in the instrument cluster, a missing connection to the diagnostic tool, and a fault memory that cannot be cleared.

The light is the most important signal that something is wrong in the restraint system. It shows the defect even when the car otherwise runs normally.

During the fault, airbags and seatbelt pretensioners may not deploy in an emergency. Therefore have the system checked promptly.
