Revised title (Updated For A3)
Revised Condition (Updated For A3)
Revised Technical Background (Updated For A3)
Customer states:
The following messages appear in the instrument cluster, mostly right after the vehicle is started:
• “High beam assist currently not available. Camera view restricted because of environmental factors.”
And/Or
• “Traffic sign detection: currently not available. Camera view restricted because of environmental factors.”
Workshop findings:
• For A3, a DTC may not be stored.
For all other vehicles, the following DTC may be stored in the front camera for the driver assist systems control
module, J1121 (address word 00A5):
•
DTC C12B3FD (front camera for driver assist systems - temporary view restriction) with symptom code
221284.
Technical Background
If the front camera recognizes a visibility restriction for more than 77 seconds, the DTC C12B3FD with symptom
code 221284 is logged, except for in A3 vehicles, where no DTC is stored, 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
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 (Figures 1 - 2).
Figure 1. Viewing area fogged up from outside.
Figure 2. Viewing area fogged up from inside.
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 in order to
clean and dry the viewing area of the camera.
