Technical Background
If the headlight switch is moved to an
intermediate position and remains there, the
warning light and the message appear after
about 10 seconds.
Once displayed, the message is turned off
after about 5 seconds. The light bulb symbol is
turned off only after the headlight switch is
turned to a defined position, and the status of
DTC 03280 is changed to sporadic.
Figure 1. The error message in the instrument
cluster.
After 40 driving cycles without an implausible
signal detected, the DTC is automatically
cleared.
Production Solution
