Mazda Forward Sensing Camera

This bulletin applies to 2016-2019 Mazda Miata MX-5 vehicles. Some vehicles may have DTC C1001:92 stored in memory. This code sets as a past record for low visibility of the Forward Sensing Camera (FSC). It does not mean that there is an actual FSC defect.

In some cases, the customer may have a concern with the Lane Departure Warning System (LDWS) and/or High Beam Control system (HBC). In other cases, this DTC might be found without a related customer concern.

If the vehicle has this DTC, do not replace the FSC. The vehicle might store C1001:92 and stop the FSC function while driving under the following conditions:

1. At night, when there is no artificial lighting such as a traffic signal, street light or reflective surface.

2. When direct or indirect sunlight makes forward visibility difficult (backlight).

3. When it’s hard to see the traffic lane due to a wet or snow covered road reflecting lights.

4. When visibility is poor in front of the vehicle due to fog.

5. When driving on a road without markings.

6. In conditions where the windshield fogs easily.

If the customer has concerns regarding the LDWS and/or HBC malfunction, confirm when the issue first happened. If the issue happened during one of the driving conditions above, explain the following two items to the customer:

  • The FSC stops the LDWS and/or HBC functions temporarily when the FSC can’t recognize the traffic lane or decides the front view is obstructed.
  • This is not a failure of the FSC. The system is disabled to avoid unintended operation.

The HBC system switches to low beam when:

  • You are approaching a vehicle or a vehicle is approaching you.
  • Driving on roads lined with street lights or well-lit cities and towns.
  • At speeds lower than 12 mph.
