SERVICE INFORMATION
The AEB system is designed to turn itself OFF during driving conditions (e.g., rain, snow,
fog, etc.) that obstruct its sensors. This behavior is normal, and no repairs should be
performed. When the AEB system performs an intentional shutdown, the customer may
state the following:


The ICC stopped working while driving,



The AEB/FEB warning light is ON, or turned ON, while driving (Figure 1),



The message “Unavailable Front Radar Obstruction” or “Forward Driving Aids
Temporarily Disabled Front Sensor Blocked See Owner's Manual” has displayed
while driving (Figure 2).

AND


DTC C1A16, C1A16-97, C2582, or C2582-97 is the ONLY DTC stored.

NOT assume that it does. See your Infiniti retailer to determine if this applies to your vehicle.
