Technical Background
If the front camera recognizes a visibility restriction for more than 77 seconds, the DTC C12B3FD with symptom
code 221284 is logged and a message appears in the instrument cluster.
As soon as visibility is restored, the message disappears and the systems are available again. The DTC becomes
sporadic.
For the unobstructed visibility of the camera, a heating element is installed under the cover of the front camera.
The heating element is activated after engine start at low temperatures or when restricted visibility is detected or
the danger of fogging up the glass exists.
Production Solution
Not applicable.
Service
1. Explain to the customer how the camera heating works.
2. Ask the customers to inspect the
viewing area of the front camera the
next time they have this message.
The viewing area of the front camera
can be fogged up both on the inside
and/or on the outside (Figure 1 and 2).
Figure 1. Viewing area fogged up from outside.

3. The customer cannot see this from the interior of the vehicle. Often it is enough to switch on the wiper
system to fix the concern.
4. If the front camera is fogged up from the inside fairly often, it can help to remove its lens hood then to clean
and dry the viewing area of the camera.
