DTC Description: Fail-Safe

WARNING: This page is about a different car, the 2019 Infiniti QX60. However, it is still accessible from the selected car via links, so may be relevant.

Fail safe mode

Vehicle behavior

Traveling control mode

Accelerator angle variation control

ECM controls the accelerator pedal depression speed to make it slower than actual speed. This causes a drop in accelerating performance and encourages the driver to repair malfunction.

NOTE: ECM does not control the accelerator pedal releasing speed.

Combustion control mode

Stratified charge combustion control at starting

No stratified charge combustion at starting (cold start).
