Protection Function

WARNING: This page is about a different car, the 2020 Infiniti QX80. However, it is still accessible from the selected car via links, so may be relevant.

The VDC warning lamp, ABS warning lamp and brake warning lamp turns ON and DTC "C118E" may be detected in self-diagnosis result of "ABS" when the brake pedal is excessively operated, such as air bleeding. This is not a system malfunction because this occurs due to the temporary decrease in accumulator fluid pressure. The system returns to normal condition when the accumulator fluid pressure reaches the specified pressure with the ignition switch ON and the VDC warning lamp, ABS warning lamp, and brake warning lamp turn OFF. After these steps, erase self-diagnosis results for "ABS" with CONSULT.
